He succeeds Scott Ridout, who resigned as President, effective September 1, 2022. As Scott has said, through a clearer “understanding and expectation of the president’s role, it has become very apparent to me that while many of my skills would be essential to this role, some of the expectations do not land in my areas of strength. I want Converge to have the best possible leadership for the future of the movement.”

During his eight years in leadership, Scott served admirably and brought many gifts to the organization. He has been a great ambassador for Converge and has successfully promoted the overall vision. Moreover, during Scott’s leadership, we planted a significant number of churches in our network thereby expanding Converge’s footprint in the United States and internationally.

Converge is a spiritually dynamic, missionally driven, relationally devoted, and culturally diverse movement of leaders who together start and strengthen churches worldwide. We believe that ministry is best accomplished when services, ministries and programs are implemented as close to the local level as possible through our regions.

Over the last year, the Board of Overseers has clarified the role of the President to ALIGN VISION, INSPIRE EVERYONE and MULTIPLY RESOURCES. We all believe that Pastor Jenkins is the right leader to unite us together to start and strengthen more churches and to send more workers out to advance the gospel.

The Converge bylaws allow for an appointment of a new President when a vacancy occurs between biennial meetings. In the interim period until our next biennial meeting in 2024, the Board of Overseers unanimously voted to appoint Pastor Jenkins as the next Converge President. Pastor Jenkins will remain the Senior Pastor of the First Baptist Church of Glenarden International in Upper Marlboro, Maryland.

Decoding Company Ethics through Pricing: The Tale of LED Floodlights

The conscience of a landscape flood light manufacturer, believe it or not, can be gauged through the prism of their specific pricing framework. Take a stride down the landscape flood light market; you will encounter a vast discrepancy in the price tags attached to identical LED floodlights. Some premium LED flood lights could be priced multifold higher than their cheaper counterparts. The raison d'être for this phenomenon can be traced back to certain unethical business practices prevalent among manufacturers.

A deep dive into these practices reveals the competitive desperation that drives some LED flood light manufacturersto drastically cut production costs to deliver at a lower price point, enticing customers with apparent 'bargains'. This tactic, though effective in securing orders, often involves cutting corners during production, resorting to substandard chips and power supplies. This not only compromises the quality of lights but also potentially threatens the branding and reputation of the manufacturers in the long run.

3 Ways Jesus Was a Marketing Genius

For those who work in marketing, whether in a church related role or otherwise, it can be tempting to separate our Christian beliefs from our occupation. But what if we could find an intersection between Jesus’ ministry and our marketing efforts? In fact, Jesus was a marketing genius. Check out how in this article written by Daniel Burk.

For those who work in marketing, whether in a church related role or otherwise, it can be tempting to separate our Christian beliefs from our occupation. But what if we could find an intersection between Jesus’ ministry and our marketing efforts? In fact, Jesus was a marketing genius.

There are three ways marketing and Christianity intersect; three ways that Jesus was a Marketing Guru, and how as someone in marketing you actually have an even greater opportunity to reflect who he was in your work and profession.

1. Marketing Strategy: Go “to the lost sheep of Israel” Matthew 15:24
What was Jesus’ primary objective? To forgive sins, and to spread his message and teaching to the ends of the earth, to “every nation” like the Bible says in Matthew 28:19.

But how did he do that?

He targeted a specific subgroup of people within a specific ethnic group with specific occupations and lifestyles.

When reading the gospel books in the New Testament, Jesus often went far out of his way to target a specific type of person in a very specific region or area of town. He knew who his target audience was, and he went to their mediums (fishing docks, water wells, synagogues, temple courts, etc.) to present “his offer”.

He extensively researched his target audience.


Luke 2:46-47: “After three days they found him in the temple courts, sitting among the teachers, listening to them and asking them questions. Everyone who heard him was amazed at his understanding and his answers.” For Jesus, targeting Jewish people who were on the fringe was not only about being humble and stooping down as God in the flesh; it was also strategic.

His core marketing team were the twelve apostles.


Their primary objective in Jesus’ ministry: “Do not go among the Gentiles or enter any town of the Samaritans. Go rather to the lost sheep of Israel.” (Matthew 10:5-6). Still in line with Jesus’ strategy and intent to go to this very specific people group at this moment in time.

(Of course later his marketing strategy changes in Matthew 28:18, when his subgroup opens to a greater group of people: all nations, not just the lost sheep of Israel).

2. He Didn’t Water Down His Offer 

Jesus knew what he had to offer: life to the full, salvation, forgiveness of sins. And he knew what the price of his offer was (1 Corinthians 6:20: “you were bought at a price”). We were “bought at a price”.

The Price: “Follow Me”

What is the price of discipleship? Following Jesus. "And whoever does not carry their cross and follow me cannot be my disciple.” - Luke 14:27

Overhead Cost: Jesus Dying on the Cross

He didn’t water down his offer, he had no discounts or sales or promotions. The price was the price. The cost was the cost. The offer IS the promotion. The fact that we even have the opportunity to choose his offer is in itself a miracle, and due to God’s grace.

For us, of course, giving promos and freebies is good and helpful for business. But in doing so it’s still a helpful dynamic for us to understand what we’re giving away: “something AWESOME, and WORTH much much more."

3. He Served First

1. Phiippians 2:1-7: “Therefore if you have any encouragement from being united with Christ, if any comfort from his love, if any common sharing in the Spirit, if any tenderness and compassion, 2 then make my joy complete by being like-minded, having the same love, being one in spirit and of one mind. 3 Do nothing out of selfish ambition or vain conceit. Rather, in humility value others above yourselves, 4 not looking to your own interests but each of you to the interests of the others.In your relationships with one another, have the same mindset as Christ Jesus:Who, being in very nature God, did not consider equality with God something to be used to his own advantage; rather, he made himself nothing by taking the very nature of a servant, being made in human likeness.”

2. "Just as the Son of Man did not come to be served, but to serve, and to give his life as a ransom for many.” Matthew 20:28

Marketing Practicals

1. When we have the perfect target group, even as few as 12 people will word-of-mouth our offering to the ends of the earth.

2. The solutions and tools we have to offer churches are ground breaking, and churches want them and need them. We can be confident of that. We are offering something great.

3. Even in the thick of grind time, imitating the heart of Jesus in our thoughts and attitudes will not only serve our customers better, but will create a greater bond here in this marketing group and in our lives beyond.

If you've taken the plunge into the world of solar panels or are considering it, you're already on a path to a greener, more energy-efficient future.

However, as you delve deeper into the realm of solar energy, you'll encounter a critical component that often remains in the shadows – the solar panel charge controller. It's a small, yet mighty device that plays a pivotal role in ensuring your solar panel system operates efficiently and effectively.

In this comprehensive guide, "Solar Panel Charge Controller: Everything You Need to Know," we will shed light on this often-overlooked hero of your solar setup. From understanding the fundamental purpose of a charge controller to demystifying the necessity of one for each solar panel, and from calculating the number of solar panels your charge controller requires to choosing the perfect controller for your system, we've got you covered.

So, whether you're a solar enthusiast eager to optimize your existing setup or a beginner looking to take the first step toward a greener tomorrow, let's embark on a journey to unravel the mysteries and intricacies of solar panel controllers. By the end of this article, you'll be armed with the knowledge needed to make informed decisions about your solar energy system and unleash its full potential.

Let's begin by demystifying the role of the solar panel charge controller and why it's a crucial component of your solar power system.

What Is Solar Panel Charge Controller?

 

A solar panel charge controller, often simply referred to as a charge controller, is a critical component of a solar power system. Its primary function is to regulate and manage the power flow between the solar panels, the battery or batteries, and the electrical loads in a solar energy system. This essential device ensures the efficient and safe operation of the entire system.

 

What Does a Charge Controller Do for a Solar Panel?

 

Here's what a charge controller does for a solar panel system:

 

  • Overcharge Protection: One of the primary functions of a charge controller is to protect the batteries in the solar panel system from overcharging. When the batteries are fully charged, the charge controller reduces or disconnects the flow of electricity from the solar panels to prevent the batteries from being overcharged. Overcharging can damage the batteries and reduce their lifespan.
  • Deep Discharge Protection: Charge controllers also prevent deep discharging of batteries. They monitor the battery voltage and disconnect the load when the battery voltage drops to a certain predefined level. Deep discharging can harm batteries, so the charge controller ensures that the batteries remain at a safe voltage level.
  • Battery Maintenance: Charge controllers help maintain the overall health of the batteries by ensuring they are charged properly. This extends the lifespan of the batteries, reducing the need for frequent replacements.
  • Optimizing Power Output: Charge controllers optimize the power output from the solar panels by regulating the voltage and current supplied to the batteries. They ensure that the solar panels operate at their maximum power point, which results in efficient energy conversion.
  • Load Control: Some charge controllers have the capability to control and manage the electrical loads in the system. This can be useful for turning on or off specific appliances or loads based on the battery's state of charge.
  • Temperature Compensation: In certain environments, temperature can affect the performance of the solar panels and batteries. Advanced charge controllers may incorporate temperature sensors to adjust the charging parameters based on the prevailing temperature conditions.

Does Each Solar Panel Need a Charge Controller?

 

Charge controllers may not be a requisite component for every solar panel system. However, they become indispensable when dealing with off-grid solar-plus-storage setups. Their primary role is to ensure that batteries do not suffer from overcharging or deep discharging, especially during periods of solar panel inactivity. If your solar system is grid-tied, the need for a charge controller diminishes since surplus power is automatically channeled away from your battery system and back into the grid.

 

How to Choose the Best Solar Charge Controller for Your System?

 

Choosing the right solar panel charge controller for your system is essential to ensure efficient and safe operation. Here's a step-by-step guide on how to make the best choice:

1.Identify Your System Type:

Determine whether your solar panel system is grid-tied or off-grid. Grid-tied systems typically don't require a charge controller because excess power is sent back to the grid. Off-grid systems with battery storage are the primary candidates for charge controllers.

 

2.Determine Battery Voltage:

Find out the voltage of your battery bank. Charge controllers are available in various voltage ratings, so it's crucial to select one that matches your battery voltage. Common battery voltages include 12V, 24V, and 48V.
 
3.Check Solar Panel Voltage:

Examine the voltage of your solar panels. Charge controllers must be compatible with the voltage produced by your solar panels. If you have multiple panels connected in series, the voltage may be higher.
 
4.Consider Battery Type:

Know the type of batteries you're using, such as lead-acid, lithium-ion, or another type. Some charge controllers are specifically designed to work with certain battery chemistries, so ensure compatibility.
 
5.Select Charge Controller Type:

Choose between two main types of charge controllers: Pulse Width Modulation (PWM) and Maximum Power Point Tracking (MPPT). MPPT controllers are more efficient and suitable for systems with higher voltage panels, while PWM controllers are cost-effective for smaller setups.
 
6.Assess System Size and Load:

Consider the overall size of your solar panel system and the electrical loads it will support. This information helps you determine the current capacity (in amps) your charge controller should handle. Make sure the controller's current rating matches or exceeds your system's requirements.
 
7.Environmental Considerations:

Evaluate the environmental conditions of your installation site, especially if it experiences extreme temperatures or weather conditions. Some charge controllers are designed to operate in harsh environments and can withstand temperature variations.
 
8.Budget Constraints:

Keep your budget in mind. MPPT controllers are generally more expensive than PWM controllers, so choose one that aligns with your financial constraints.
 
9.Consider Future Expansion:

If you plan to expand your solar panel system in the future, ensure the charge controller can accommodate the increased capacity. Select a controller with room for growth.
 
10.Seek Professional Advice:

If you're uncertain about your choice, consult with a solar energy professional or contact the charge controller manufacturer for expert guidance.

In electronics assembly, reflow soldering involves applying solder paste to contact pads on printed circuit boards (PCBs). As the solder paste undergoes heating in order to establish electrical connections, it serves as the medium for attaching electrical components to the board. During the process of reflowing, the solder paste is heated in order to establish electrical connections.
 
The main difference between reflow soldering and traditional soldering is the absence of a soldering iron. Instead, heated air is used to liquefy the solder and facilitate component integration.

All components of the assembly are conveyed through a reflow oven equipped with an infrared lamp, which provides the heat needed to melt solder and bond electrical elements.

Moreover, the infrared lamp's temperature can be precisely controlled. By gradually increasing the temperature, a sudden rise in temperature can compromise solder joints and make them vulnerable to thermal shock. Thermal shock-related issues can be avoided through the implementation of reflow soldering.

What Is Reflow Soldering?

 
Reflow soldering stands as the prevailing soldering technology within the microelectronics industry, primarily for the assembly of Surface Mounted Devices (SMDs). This process plays a pivotal role in the large-scale production of Surface Mount Devices, serving to establish their electrical and mechanical connections to Printed Wiring Boards (PWBs).

Preceding the actual reflow soldering procedure, a series of essential steps are executed. These include the application of solder paste onto the designated contact surfaces or pads of the PWB and the precise placement of components onto the deposited solder paste. Subsequently, the reflow process is initiated, subjecting the entire assembly to elevated temperatures surpassing the melting point of the solder alloy. As the temperature gradually decreases, the solder alloy solidifies, engendering the formation of robust and dependable solder joints.
 

Pros of Reflow Soldering

 
  • It is preferable for SMT assembly
  • It induces minimal thermal shock.
  • It is one of the most reliable soldering technique
  • It has options for limited soldering
  • It requires only a minimum level of monitoring
  • It results in reduced material wastage.
  • Specific PCB areas can be soldered using this technique.
 

Reflow Soldering Process and Tips

 
Reflow soldering stands as the foremost and extensively employed technique for connecting surface mount technology (SMT) components to a printed circuit board (PCB). This procedure centers on establishing satisfactory solder connections through the utilization of preheated components, affording the opportunity to melt the solder without incurring damage from excessive heat.

In order to craft an appropriate reflow profile, thermocouples are affixed to a basic assembly, often utilizing high-temperature solder, positioned at various locations to gauge the temperature variations across the PCB.

Please take note of the following recommendation: It is advisable to place a thermocouple on the pad located at the front edge of the printed board and another thermocouple towards the board's center. This method of assessing temperature differentials across the board through thermocouples is commonly referred to as "DeltaT."

The reflow profile encompasses four key phases of the process that require your vigilant consideration:
 
  • Proheat- As part of this process, the printed circuit board, components, and solder are heated to a specific dwell temperature or soak temperature, and the main aspect is not to heat the components or solder too rapidly (usually no more than +2 degrees per second). As a result of fast heating, component defects may occur, such as slattering or cracking of solder paste.
  • Soak- During this part of the process, the components are allowed to reach the required temperature before going on to the next reflow stage. The soaks usually last between 60 and 120 seconds.
  • Reflow-To form a liquid solder paste in the oven, the temperature is raised above its melting point. To ensure that "wetting" occurs between the printed board and the components, the solder must be held above the melting point temperature for a period of time (time above liquidus). To prevent brittle solder joints, the time should not exceed 30 to 60 seconds. It is also important to know that the peak temperature has to be strictly controlled as many of the components can fail if exposed to excessive heat. If the reflow profile does not provide sufficient heat, it will result in bad solder joints, which is one of the most common defects.
  • Cooling- It is not healthy to heat the assembly rapidly, so make sure to never cool it down too rapidly, because it could cause malfunctions. The recommendation is to keep cooling above 3 degrees a second.
 

Reflow Soldering Temperature Requirements

 
The printed circuit board (PCB) industry encompasses a diverse array of components that necessitate specific reflow temperatures.

In the case of Sn/Pb solders, the melting point temperature generally reaches its zenith between 215°C to 245°C, with a duration of approximately 20-60 seconds above 183 degrees.

For lead-free soldering, the reflow temperature should attain 260°C.

Reflow soldering ovens commonly feature distinct temperature zones, with periodic adjustments in temperature following a predetermined curve. These adjustments are made in accordance with the assembly's particulars and temperature prerequisites.

Hvttec has a reflow soldering oven with 8 temperature zones which can be used for reflow soldering.

Suitable Machines and Equipment

 
The preferred method for reflow soldering involves employing an industrial convection oven to attach surface mount technology (SMT) components onto a printed circuit board (PCB).

A wide array of reflow soldering machines exists, each specializing in distinct designs, processing speeds, materials, and PCB specifications. It is crucial for the oven to be of an appropriate size to seamlessly accommodate the production pace of the pick-and-place equipment.

Here's a method for calculating the production line speed:

The functional differences between a microcontroller and a microprocessor are important for embedded systems engineers and product developers in the electronics industry. While both types of components are essential for designing and building various kinds of electronic devices, their definitions alone can make it difficult to distinguish between them.

Microcontrollers can be categorized as small computers or "supercomputers" that are made from a single integrated circuit chip that contains one or more cores of computing power, along with other peripherals (memory, serial interfaces, timers, programmable I/O peripherals, etc.).

A microprocessor refers to a computer processor that incorporates the functions of a central processing unit (CPU) onto just a few (and often only one) integrated circuits, which are used to carry out the operation of that computer.

There are many similarities between microcontrollers and microprocessors on the surface. They are both examples of single-chip processors which have increased reliability and reduced the cost of processing power, thereby accelerating the proliferation of computing technology. Each of these processors executes computing logic on a single chip, and they are found in millions of electronic devices worldwide.

Here's a blog post that compares microcontrollers and microprocessors to help clarify the differences between them. You will gain a clear understanding of which of these components should power your next computer engineering project as we examine every difference between a microcontroller and a microprocessor, from architecture to applications.
 

What's the Difference Between a Microcontroller and Microprocessor?

 
Choosing the right computer processor for your project matters a lot. It affects how you design and what results you get. So, knowing the main options and their unique features is essential. Let's look at how a microcontroller and microprocessor differ.
 

Microcontroller vs. Microprocessor Architecture

 
While both do similar tasks, their architectures are quite different. A microcontroller has everything it needs for computing on a single chip. That means the CPU, memory, controls for interruptions, timers, serial ports, and more are all on that one chip. No external circuits are needed.

On the other hand, a microprocessor includes a CPU and some extra chips that supply memory, interfaces, inputs, timers, and other parts. People sometimes use "microprocessor" and "CPU" interchangeably, but a microprocessor is like a single chip that has a CPU. This chip can connect to external stuff like a control bus or data bus for inputs and outputs.

So, microcontrollers are self-contained, while microprocessors deal with external things. These differences have their own pros and cons.
 

Microcontroller vs. Microprocessor Applications

 
Microcontrollers and microprocessors both use CPUs in computing. They have somewhat separate applications, though.

Microprocessors need extra chips to make a microcomputer system. They are great for personal computers where you need powerful processors for different jobs. You can easily upgrade parts like RAM in microprocessors.

Microcontrollers are all-in-one chips that use low power and do a single job. They're mostly used in embedded systems where things have to run on their own for a long time.
 

Three Key Differences: Cost, Speed, and Power

 
Cost

In general, microcontrollers tend to be less expensive than microprocessors, as microprocessors tend to be manufactured with more expensive devices that will use external peripherals to boost performance. They are also significantly more complex, as they are intended to perform a variety of computational tasks, while microcontrollers usually perform a particular function. In order to support more complex computational tasks, microprocessors require a robust external memory source.

Code for specific applications is written and compiled by engineers and uploaded to a microcontroller, which contains all of the computing features and components needed to execute the code internally. Since microcontrollers have narrow individual applications, they often require less memory, computing power, and complexity than microprocessors, which is why they are more affordable.

Speed

A high-quality microcontroller differs significantly from industry-leading microprocessor chips when it comes to overall clock speed. As a result, microcontrollers are designed to handle specific tasks or applications, while microprocessors are designed to handle more complex, robust, and unpredictable computing tasks. 

Using just the right amount of speed and power to accomplish a given task is one of the key design advantages associated with microcontrollers. That means using just the right amount of power and speed to accomplish the task. Therefore, many microprocessors are clocked at speeds of up to 4 GHz, while microcontrollers operate at 200 MHz or less.

While on-chip components help microcontrollers perform functions quickly, microprocessors sometimes operate more slowly as a result of their dependence on external peripherals.

Power Consumption

There are several benefits associated with microcontrollers, including their low power consumption. Microcontrollers can perform a variety of tasks at relatively low speed, which means that they use less power than processors with robust computational capabilities. An implementation's power consumption is an important factor: a processor that consumes a lot of power may require an external power supply, whereas a processor that consumes a small amount of power could be powered for a long time by just a small battery. 

A microcontroller can be much more cost effective than a microprocessor for tasks that require little computational power.
 

Microcontrollers for Embedded Systems

 
Microcontrollers work well for embedded systems:
 
  • They have everything on one chip.
  • They're made for one job.
  • They can be optimized.
  • They use low power.
  • They're cost-effective.
 

Summary

 
In the end, microcontrollers and microprocessors are different ways of organizing and optimizing a computing system based on a processor. A microprocessor houses a more powerful CPU on a single chip that connects to external peripherals, as opposed than a microcontroller which houses the CPU and all peripherals on the same chip. In general, microprocessors are more useful for applications requiring more complicated and versatile computing operations than microcontrollers, which are optimized for a low-power, dedicated applications - ideal for embedded systems.

We have the tools you need to work with programmable microcontrollers, whether you're an embedded systems engineer or developer. With our host of adapters and protocol analyzers, you can speed up the process of debugging your product and reduce its time to market.

Solar power systems offer an eco-friendly and cost-effective way to harness the energy of the sun and convert it into usable electricity. Whether you're considering solar panels for your home or a remote off-grid installation, solar charge controllers play a vital role in ensuring the efficiency and longevity of your system. In this article, we'll explore how solar charge controllers work and the various types available to help you make informed decisions for your solar project.
 

How Does a Solar Charge Controller Work?

 
The first solar charge controller schematic, depicted in Figure 1, illustrates the connection of a solar charge controller to power a direct current (DC) load. The second schematic, shown in Figure 2, pertains to an alternating current (AC) load.
 
Figure 1: Off-grid Diagram with DC Load
 
off-grid-diagram-with-dc-load
 
When installing a solar charge controller, it is advisable to follow a specific order for connecting and disconnecting:
 
  1. Connect the battery to the controller first.
  2. Connect the PV array to the controller.
  3. Connect the electrical load to the controller.
 
When disconnecting, you should reverse this order. The battery supplies power to the controller, so always ensure that the solar panels and loads are disconnected before connecting or disconnecting the battery from the controller. To enhance safety and simplify installation and breakdown, it's recommended to have disconnect switches in the connections between the battery, load, PV array, and the controller.
 
In the wire diagram schematic with a DC load, sunlight reaches the solar modules, which convert solar energy into DC electrical power. This power is then delivered to a charge controller. The charge controller regulates the amperage and voltage supplied to the loads, and any excess power is directed to the battery system to maintain the state of charge without overcharging. During the evening when there is no sunlight, battery power is used to operate the load.
 
You may notice that the battery is grounded at the negative battery terminal. This is because all our PWM and MPPT controllers share a common negative ground. Therefore, it is possible to establish a common negative ground for the entire system, including the solar array, controller, battery, and load. This configuration complies with NEC code requirements for grounding. For controllers that lack an equipment ground terminal lug, you can directly connect an equipment ground to the controller enclosure for any metal parts.
 
Figure 2: Off-grid Diagram with AC Load
 
off-grid-diagram-with-ac-load
 
The next diagram, as seen in Figure 2, illustrates the components and connections required to power an AC load. This schematic with an AC load closely resembles the previous DC load example. However, in this scenario, an inverter has been added to the system. The inverter's role is to convert DC power from the battery into AC power, which can be utilized to operate AC loads, such as the TV shown in the schematic.
 
It's important to note that the inverter is connected and powered directly from the battery, not from the controller's load terminals, as in the DC load example. This arrangement is necessary because inverters can produce a high energy surge during startup, and this surge may exceed the rated capacity of the charge controller. Batteries, on the other hand, can meet the high-energy surge requirement.
 

Charge Controller Types:PWM Vs MPPT

 
It can be seen from the chart below that PWM controllers operate at battery voltage and are smaller, while MPPT controllers operate at maximum power voltage using newer technology. As a result, the array voltage gets increasingly higher than the battery voltage in colder conditions, maximizing the amount of power being produced. Moreover, MPPT controllers can operate at higher voltages and lower array currents, which can result in fewer strings in parallel and smaller wire sizes.
 
A PWM controller can only be used with arrays matched to the battery voltage, so what modules can be used are limited. Many 60 cell modules have a maximum power voltage (Vmp) equal to about 30V, making them suitable for MPPT controllers, but not PWM controllers.
 
In short, what's better, PWM or MPPT? All things being equal, MPPT is the newer technology that harvests a greater amount of energy. Despite MPPT's advantages, it is not always a smart choice to choose a PWM controller, especially for smaller systems or in warm climates where MPPT boosts are less noticeable.
 
 
PWM vs. MPPT Solar Charge Controller Comparison
 
PWM ControllersMPPT Controllers
Array voltage is “pulled down” to battery voltage    Convert excess input voltage into amperage
Generally operate below Vmp    Operate at Vmp
Suitable for small module configurationsSuitable for large module configurations that have a lower cost per watt
Often chosen for very hot climates which will not yield as much MPPT boost    Provide more boost than PWM, especially during cold days and/or when the battery voltage is low
 
 

PWM Charging


Conventional solar regulators featuring PWM (Pulse Width Modulation) charging function by creating a direct connection from the solar array to the battery bank. During the bulk charging phase, when there is an uninterrupted connection from the array to the battery bank, the array's output voltage aligns with the battery voltage. The battery voltage undergoes slight adjustments based on the array's current supply and the battery's size and characteristics.

MPPT Charging


Morningstar MPPT controllers incorporate TrakStar technology, which is engineered to swiftly and precisely determine the Vmp (maximum power voltage) of the solar array. TrakStar MPPT controllers employ a technique where they 'sweep' the solar input to identify the voltage at which the array produces the maximum power. The controller captures power from the array at this Vmp voltage and converts it to the battery voltage, simultaneously boosting the charging current.  

Why Choose PWM Over MPPT

 
The comparison between PWM and MPPT may raise questions about why one would opt for a PWM controller over an MPPT controller. Several factors may reduce or negate the advantages provided by MPPT controllers. Considerations should include the cost, as MPPT controllers generally come at a higher price point than their PWM counterparts. When deciding on a controller, it's essential to assess the additional cost of MPPT in relation to the following factors:

Low Power Applications: Low power, specifically low current charging applications, might achieve similar or even superior energy harvest with a PWM controller. PWM controllers maintain relatively consistent harvesting efficiency regardless of the system's size. In contrast, MPPT regulators may exhibit reduced harvesting efficiency when used in low- power applications. It's crucial to review efficiency curves available in Morningstar MPPT controller manuals when making a regulator selection.

Climate Considerations: The most significant benefit of an MPPT regulator is often observed in colder climates where Vmp (voltage at maximum power) is higher. Conversely, in hotter climates, Vmp decreases, reducing MPPT harvest compared to PWM. High average ambient temperatures at the installation site may render the advantages of MPPT less economical.

Full Battery Conditions: Systems in which the solar array's power output significantly exceeds the power draw of the system's loads may result in the batteries remaining at full or near-full charge most of the time. In such cases, the increased harvesting capability of an MPPT regulator may be unnecessary, especially if autonomy is not a critical factor.
 

Why Choose MPPT Over PWM

 
Opting for MPPT controllers offers several advantages:

Increased Energy Harvest: MPPT controllers operate at array voltages above battery voltage, enhancing the energy harvest from solar arrays by 5 to 30% compared to PWM controllers, depending on climate conditions. The array's voltage and amperage are continually adjusted throughout the day to maximize power output.

Less Module Restrictions: MPPT controllers, operating arrays at voltages higher than battery voltage, can be used with a broader range of solar modules and array configurations. They can also support systems with smaller wire sizes.

Support for Oversized Arrays: Unlike PWM controllers, MPPT controllers can accommodate oversized arrays that might otherwise surpass the maximum power limits of the charge controller. The controller manages this by limiting the array's current intake during periods of high solar energy supply, usually in the middle of the day. While excess energy from the array is regulated during this time, oversized arrays can deliver more power during the early and late parts of the day, compared to smaller non-oversized arrays.

In electronics assembly, reflow soldering involves applying solder paste to contact pads on printed circuit boards (PCBs). As the solder paste undergoes heating in order to establish electrical connections, it serves as the medium for attaching electrical components to the board. During the process of reflowing, the solder paste is heated in order to establish electrical connections.
 
The main difference between reflow soldering and traditional soldering is the absence of a soldering iron. Instead, heated air is used to liquefy the solder and facilitate component integration.

All components of the assembly are conveyed through a reflow oven equipped with an infrared lamp, which provides the heat needed to melt solder and bond electrical elements.

Moreover, the infrared lamp's temperature can be precisely controlled. By gradually increasing the temperature, a sudden rise in temperature can compromise solder joints and make them vulnerable to thermal shock. Thermal shock-related issues can be avoided through the implementation of reflow soldering.

What Is Reflow Soldering?

 
Reflow soldering stands as the prevailing soldering technology within the microelectronics industry, primarily for the assembly of Surface Mounted Devices (SMDs). This process plays a pivotal role in the large-scale production of Surface Mount Devices, serving to establish their electrical and mechanical connections to Printed Wiring Boards (PWBs).

Preceding the actual reflow soldering procedure, a series of essential steps are executed. These include the application of solder paste onto the designated contact surfaces or pads of the PWB and the precise placement of components onto the deposited solder paste. Subsequently, the reflow process is initiated, subjecting the entire assembly to elevated temperatures surpassing the melting point of the solder alloy. As the temperature gradually decreases, the solder alloy solidifies, engendering the formation of robust and dependable solder joints.
 

Pros of Reflow Soldering

 
  • It is preferable for SMT assembly
  • It induces minimal thermal shock.
  • It is one of the most reliable soldering technique
  • It has options for limited soldering
  • It requires only a minimum level of monitoring
  • It results in reduced material wastage.
  • Specific PCB areas can be soldered using this technique.
 

Reflow Soldering Process and Tips

 
Reflow soldering stands as the foremost and extensively employed technique for connecting surface mount technology (SMT) components to a printed circuit board (PCB). This procedure centers on establishing satisfactory solder connections through the utilization of preheated components, affording the opportunity to melt the solder without incurring damage from excessive heat.

In order to craft an appropriate reflow profile, thermocouples are affixed to a basic assembly, often utilizing high-temperature solder, positioned at various locations to gauge the temperature variations across the PCB.

Please take note of the following recommendation: It is advisable to place a thermocouple on the pad located at the front edge of the printed board and another thermocouple towards the board's center. This method of assessing temperature differentials across the board through thermocouples is commonly referred to as "DeltaT."

The reflow profile encompasses four key phases of the process that require your vigilant consideration:
 
  • Proheat- As part of this process, the printed circuit board, components, and solder are heated to a specific dwell temperature or soak temperature, and the main aspect is not to heat the components or solder too rapidly (usually no more than +2 degrees per second). As a result of fast heating, component defects may occur, such as slattering or cracking of solder paste.
  • Soak- During this part of the process, the components are allowed to reach the required temperature before going on to the next reflow stage. The soaks usually last between 60 and 120 seconds.
  • Reflow-To form a liquid solder paste in the oven, the temperature is raised above its melting point. To ensure that "wetting" occurs between the printed board and the components, the solder must be held above the melting point temperature for a period of time (time above liquidus). To prevent brittle solder joints, the time should not exceed 30 to 60 seconds. It is also important to know that the peak temperature has to be strictly controlled as many of the components can fail if exposed to excessive heat. If the reflow profile does not provide sufficient heat, it will result in bad solder joints, which is one of the most common defects.
  • Cooling- It is not healthy to heat the assembly rapidly, so make sure to never cool it down too rapidly, because it could cause malfunctions. The recommendation is to keep cooling above 3 degrees a second.

Best 5 Disposable Trocar Manufacturers

When it comes to surgical procedures, precision, safety, and innovation are paramount. Disposable trocars, essential tools in laparoscopic surgeries, play a crucial role in ensuring a minimally invasive and efficient approach. With a myriad of options available, choosing the right disposable trocar is pivotal for successful surgical outcomes. Here, we present the best 5 disposable trocar manufacturers that stand out in the industry for their commitment to quality, reliability, and cutting-edge technology.
 
 
disposable laparoscopic trocar
 

What Is Disposable Trocar?

 
A disposable trocar is a medical device commonly used in minimally invasive surgical procedures. It plays a crucial role in laparoscopic surgeries, providing a means to access the abdominal cavity through a small incision. The trocar consists of several key components:
 
  1. Sharp Tip: The trocar features a pointed, often conical or pyramidal, tip that facilitates the initial penetration of the abdominal wall.
  2. Protective Sleeve (Cannula): Surrounding the sharp tip, there is a protective sleeve or cannula. This tubular structure creates a pathway for other surgical instruments to be introduced into the abdominal cavity once the trocar has created an entry point.
  3. Valve Mechanism: Many disposable trocars incorporate a valve mechanism to prevent the escape of gases (like carbon dioxide) used to inflate the abdominal cavity during laparoscopic procedures. This helps maintain the necessary pneumoperitoneum for clear visualization.
  4. Ergonomic Handle: Equipped with an ergonomic handle, the trocar allows surgeons precise control during the insertion process.
  5. Disposable Design: As the name suggests, disposable trocars are designed for single use. This eliminates the need for reprocessing and sterilization after each surgery, reducing the risk of cross-contamination and ensuring a high level of hygiene.
 
Disposable trocars are integral to laparoscopic surgeries, where small incisions are preferred over larger ones. These procedures involve inserting a camera (laparoscope) and other surgical instruments through trocars to perform various surgeries with minimal trauma to the patient. The disposable nature of these trocars aligns with contemporary medical standards, emphasizing safety, efficiency, and infection control in surgical practices.
 

What Are the Different Types of Trocars in Laparoscopy?

 
Abdominal access systems, commonly known as trocars, have evolved significantly in modern surgery and are available in a diverse range of sizes, typically ranging from 3mm to 12mm and beyond. These trocars fall into two main categories:
 

1.Cutting Trocars:

 
  • Feature a sharp metal or plastic blade for cutting through various tissue layers.
  • Facilitate easy insertion into the abdominal cavity when pressure is applied.
 

2.Dilating Trocars:

 
  • Have a blunt tip that separates and dilates tissue under pressure.
  • Represent a recent innovation aimed at eliminating the cutting blade, thereby reducing the risk of damaging internal organs during insertion.
 
Within these categories, a wide array of specialized trocars are designed to cater to specific needs. Examples include working ports, camera ports, and static or retraction ports. The selection of the appropriate trocar depends on the nature of the surgical procedure.

For straightforward surgeries like diagnostic laparoscopies, a 5mm optic trocar is typically sufficient, providing ample light and control. More intricate procedures may demand brighter illumination and a clearer visual, making a 10mm optic trocar a more suitable choice.

Standard procedures often involve two working trocars on either side of the lower abdomen, with 5mm ports commonly used to allow access for secondary instruments. Smaller trocars can be employed for uncomplicated cases, while larger trocars, typically 12mm or above, are reserved for situations requiring a morcellator or the removal of large tumors.

The rising popularity of disposable trocars is notable, offering the advantage of a guaranteed sharp tip that requires less pressure for insertion. However, this comes with an associated increase in cost and environmental impact.

In contrast, reusable trocars come with two different tip options – conical and pyramidal. The pyramidal tip, being sharper, is more commonly preferred. While reusable trocars are more cost-effective, they necessitate thorough cleaning, sterilization, and regular sharpening and maintenance. The choice between disposable and reusable trocars depends on factors such as cost considerations, environmental concerns, and specific procedural requirements.

Vision and Goals

12258361676?profile=RESIZE_710x

volunteers  needed for demonstration
5 occupations - dentist, hairdresser, mechanic, doctor, pharmacist

5 Volunteers – all with the same problem but different response actions

 

Person with very sore open infected leg, painful, weeping sore.

Same problem – different beliefs and actions

Who to go to, to get leg fixed?


1/ Visits dentist, my leg is sore, dentist says, open your mouth,
I see the problem, your back molar is twisted it needs to come out.

Reaction – I am not sure.

 

2/ Lady, my friend is a hairdresser, I need a haircut, I will go and ask her.
Sitting in chair getting her hair done and asks about leg

I see the problem, its not clean, I recommend this shampoo to all my customers it works wonders for them, take some and try it.

Shampoo on leg – condition gets worse and more painful.

 

3/ Smart guy, My mechanic says he can fix anything, he’s fixed my car many times.

I see the problem, If you put this high grade oil in your car it works better, maybe it will work for your leg too.

Puts oil on leg, infection and pain worse.

 

4/ Even smarter guy, Maybe I should go to the doctor. Visits doctor.

I see the problem, you have an infection, we need to kill the bacteria with cream and antibiotic tablets, go get these and apply cream to leg and take antibiotics, come back and see me in a week.

 

Man goes to Pharmacy,  the cream is cheap but the tablets expensive.

Doesn’t buy tablets because he can’t afford.

Leg stops weeping but infection swelling and pain still there,

back to doctor in a week.

I couldn’t afford tablets but why is my leg not better?

 

5/ Even smarter still lady, Maybe I should go to the doctor.

Visits doctor

I see the problem, you have an infection, we need to kill the bacteria with cream and antibiotic tablets, go get these and apply cream to leg and take antiobiotics, come back and see me in a week.

Goes to pharmacy, gets cream, can’t afford tablets, goes home to family and friends, I have to get $X, searches, asks, borrows from family friends, goes back to pharmacy, gets tablets and uses.
After a week goes back to doctor, leg healed.

 

POINT

Don’t take your advice from someone who is not experienced AND qualified in the appropriate field.
Take the action recommended by the expert.

Do Whatever it Takes.

 

 

Jesus had goals
One day Jesus said to his disciples, “Let us go over to the other side of the lake.” So they got into a boat and set out. Lk 8.22

Then a storm came but he stilled the storm because he had a goal. 
He did not say, let's go out in the boat, go to the middle of the lake and drown in a big storm.
He had a goal and did whatever it took to complete the goal.  

 

Set his face to go to Jerusalem Luke 9.51

As the time approached for him to be taken up to heaven, Jesus resolutely set out for Jerusalem.

Had clear goals and pursued them, in spite of difficulties.

 

Difference between a failure and a person who has failed.

you are NOT a failure, you are more than conquerors, BUT …

you may have failed:-

And continue to fail

perhaps because

  • You take advice from unqualified people
  • You don’t follow the advice of experts
  • Have been beaten by the circumstances, economy, culture, resistant people


BUT you don’t have to stay there …


You may have a general idea of a vision you want to follow

But most will not get there

Because:-

  • you don’t even ask any questions
  • some ask, but not the right questions,
  • you don’t ask the right people and
  • when you do get good advice, you don’t follow it.

 

You are either:-

  • Stubborn
  • Rebellious
  • Stupid
  • Or looking for a quick way or shortcut


What does God say about the person that knows to do good but does not do it?
To him who fails to respond to God, to him it is sin.

To act without faith is sin.

 

A few succeed,

  • They follow the advice of the expert
  • and act on it
  • and persist in faith despite obstacles until it works.

 

A success is a person that got up and tries again after every failure

A failure is one who says:-  

  • It can’t be done
  • I don’t know how to do it
  • I can’t afford it
  • It’s too hard
  • Nobody will help me
  • In our country you can’t do that because – long list of cultural, economic or social excuses.

 

Elite Sportspeople spend hours, weeks months and years in obscurity – practicing for their big moment.
But the sports stars all have one thing that most Christian leaders lack -

GOALS

Clearly defined, exact objective, time specific

And a
Strategy to get to the goal.

 

If it costs you nothing you will not value it.
if the cost is beyond your natural means, must use faith and persistence to obtain.

Stop looking for a free everything.

Some won’t come to an event if it’s not free lunch.

Free will not help you.

Pay for it and appreciate it.

I apologies on behalf of all western missionaries that have come to you and taught by their example that you don’t have to pay for anything.
They have (perhaps unknowingly), taught you a poverty mentality.

You must escape the poverty mentality.

Those wanting a free lunch are free loaders – they will still be looking for a free lunch when Jesus comes and their excuse for not doing the job will be we couldn’t afford it.

Lk 13.27 But he will reply, ‘I don’t know you or where you come from. Away from me, all you evildoers!’

 

John 6.26Jesus answered, “Very truly I tell you, you are looking for me, not because you saw the signs I performed but because you ate the loaves and had your fill27Do not work for food that spoils, but for food that endures to eternal life, which the Son of Man will give you. For on him God the Father has placed his seal of approval.”

 

If you have a vision, but no goals

You will –

  • Never know what is best to do next
  • Easily get diverted from the best path
  • Not knuckle down and work hard because there is no deadline
  • And never know whether you have achieved your goal.

 

Follow the blueprint
Exodus 25:9 You must make the tabernacle and design all its furnishings according to the pattern ...

 

As part of our program to help you learn how to hear God and set Godly specific goals for your ministry we have established

Growing African Christian Leaders facebook group

12258362494?profile=RESIZE_710xWe discovered by asking admission questions. 
1/ What is the biggest goal you have in your ministry? Share the specific activity or project, the deadline and measurement.

Less than 10% could provide a clear goal.

 

We changed question to:- 

1/ What is the next big goal/project your ministry is working towards? Include specific project, how many, what size, describe the people by location, ethnicity, age, gender, interest or other factor & date to achieve.

Still only 17% can explain a clear goal that they have.

That's why we provide this training, to help you understand, create goals and fulfil them. 

Now after more 3000 applications, & 2500+ waiting to get in that didn’t provide answers at all.
We can clearly say that:-  
Africans need help with setting goals


That’s why we have a 10 Day Challenge to show you how to hear from God and do it,

and take your ministry to the next level in 10 days – and its free,

but you won’t learn if you don’t do the assigned tasks.

Metal cutting is an essential process in various industries, from automotive manufacturing to construction. When it comes to achieving precision and efficiency, professionals always turn to ultra-thin cutting discs. These advanced tools offer exceptional performance, allowing users to slice through metal with ease, comfort and speed. In this article, we will delve into the art of metal cutting using ultra-thin cutting discs, providing insights and tips for professionals in the field.

 

What are Ultra-Thin Cutting Discs?

Ultra-thin cutting discs are designed to make precise cuts in metal materials. These discs are significantly thinner than conventional cutting discs, which enables faster cutting speeds and reduced material waste. Typically, These discs have a thickness of 0.8 millimeters and are available in two common sizes: 115 x 0.8 x 22.23 and 125 x 0.8 x 22.23. The smaller size, 115 x 0.8 x 22.23, is suitable for more intricate cutting tasks, while the larger size, 125 x 0.8 x 22.23, is ideal for heavier-duty applications. Their thin profile allows for precise and controlled cuts.

How to Choose the Right Cutting Disc?

To achieve optimal results, it is crucial to select the appropriate cutting disc for the task at hand. Consider the following factors when choosing a disc:

  1. Material: Different cutting discs are designed for specific metal materials. Ensure that the disc you select is suitable for the metal you intend to cut, whether it’s steel, aluminum, or stainless steel.
  2. Disc Diameter:The diameter of the cutting discaffects the depth of cut and the stability of the tool. Choose a disc with a diameter that suits the size and thickness of the metal you are working with.
  3. RPM Rating: Each cutting disc has a recommended maximum revolutions per minute (RPM) rating. Ensure that the disc is compatible with the RPM of your angle grinder or cutting tool to prevent accidents and ensure optimal performance.

 

How Can We Ensure the Utmost Safety?

Working with metal cutting discs requires strict adherence to safety protocols. Here are some essential safety measures to follow:

  1. Protective Gear:Always wear appropriate personal protective equipment (PPE), including safety glasses, gloves, and ear protection. A face shield or mask can provide additional protection against metal chips and sparks.
  2. Secure Workpiece: Ensure that the workpiece is firmly secured before beginning the cutting process. Use clamps or a vise to prevent movement or vibrations that could compromise the accuracy of the cut.
  3. Avoid Excessive Pressure: Let the cutting disc do the work. Applying excessive pressure may cause the disc to overheat or break. Allow the disc to glide smoothly through the metal, maintaining a steady and controlled pace.

 

Techniques for Effective Cutting

Achieving clean and accurate cuts with ultra-thin cutting discs requires skillful technique. Here are a few tips to enhance your cutting proficiency:

  1. Positioning: Position yourself comfortably and maintain a firm grip on the tool. Stand to the side of the cutting line to avoid potential kickbacks or flying debris.
  2. Angle of Approach: Approach the metal at an angle between 5 to 15 degrees. This angle helps reduce friction and ensures smooth cutting while preventing the disc from binding.
  3. Start Slowly: Begin cutting at a slow speed to establish a groove. Once the groove is established, gradually increase the speed to maintain a consistent and controlled cutting process.
  4. Cooling Intervals:Allow short cooling intervals during prolonged cutting to prevent overheating of the disc. This practice helps to prolong the lifespan of the disc and maintain cutting efficiency.

 

Maintenance and Disc Replacement

Regular maintenance and disc replacement are vital to ensure optimal cutting performance and extend the lifespan of your ultra-thin cutting discs. Follow these maintenance tips:

  1. Inspection:Before each use, inspect the cutting disc for any signs of damage, cracks, or wear. Never use a damaged disc, as it may shatter during operation.
  2. Cleaning: Remove metal shavings and debris from the disc regularly. Use a wire brush or a dedicated cleaning tool to maintain its cutting effectiveness.
  3. Disc Replacement: Discs wear down over time, so it is essential to replace them when they become too thin or worn out. Always have spare discs on hand to avoid interruptions during projects.

 

Conclusion

Mastering metal cutting with ultra-thin cutting discs requires a combination of knowledge, skill, and the right tools. By understanding the basics of these discs, choosing the appropriate cutting disc for the job, prioritizing safety, employing effective cutting techniques, and maintaining your tools, you can achieve precise cuts in metal materials with efficiency and professionalism. Embrace the power of ultra-thin cutting discs, and let them be your ally in tackling metal cutting challenges.
