Top Standard Solar Charge Controllers (MPPTs) for Sale in South Africa

More South Africans are taking charge of their own energy generation needs and with solar energy, the option of becoming independent of the power system is easier to achieve than it has ever been. Solar energy should be the more obvious choice when it comes to renewable energy and as people look for ways to avoid the national power grid, solar energy systems are the way forward.

At Africa Power Equipment, we’ve fast become the go-to company for those looking to invest in a high-quality solar energy system that will last a lifetime. We have gone above and beyond to make sure that we have sourced the best products and systems for our clients to use in both their homes and their businesses. We offer a wide variety of solar products, including solar charge controllers for sale at competitive prices. Our products can be used to create an outstanding solar system more than capable of meeting all of your power needs.

To generate power, it is important to have all of the bits and pieces that come together to create the full system. Sometimes buying all of the parts individually is not necessary, when you buy a solar kit. These kits are designed to include everything you will need, but the downside is that sometimes such systems won’t allow you to upgrade your system when your power needs to change.

The upside of going with this option is that it can be a lot more affordable and a lot less of a hassle.

But if you are aiming to customise every part of the system, down to the very last detail, then you will have to make sure that you buy each part, including the charge controller.

What is a solar charge controller?

Although the charger is not the biggest part of the system, it is certainly an important part. A solar charger is a device that is used to keep the solar battery charged. It is placed between the solar panels and the battery and it will regulate the battery as it is charged, ensuring that the solar battery is never overcharged, something that can end up completely destroying the battery and costing you a small fortune.

The more advanced solar chargers including the more modern variety, are designed to include a whole lot more features than the original chargers.

Solar controllers are often rated according to their maximum input voltage and the maximum charge current.

MPPT vs. PWM Solar Charger

At Africa Power Equipment we specialise in selling the MPPT charger, but since there are two different types of chargers on the market, it helps to know the difference between the MPPT and the PWM solar charger, so that you can make the right choice based on your needs.

The PWM Charger

The PWM charger is also known as the Pulse Width Modulation charger controller. This device has a direct connection from the solar set up to the battery and the controller also has a basic rapid switch that helps to control the battery charging process. This switch remains open until the battery reaches its full charge. Once it reaches that point, the switch will open and close rapidly to maintain the battery’s constant voltage.

The problem with the PWM charger is that because of the way the charger works, the solar panel voltage is designed to match the battery voltage. This can reduce the operating efficiency as the panel output is reduced.

If you are looking for a low-cost option, particularly for a smaller system, then the PWM charger is the way to go. The PWM charger is the ideal option if you are using your solar system to power solar lighting, camping gear, and even cell phones.

The MPPT Charger

Also known as a Maximum Power Point Tracker, the MPPT charger is a lot more advanced than the PWM charger. These chargers allow the solar system to function at a maximum PowerPoint. In terms of efficiency, your controller can be around 30% more capacity. The reason why your MPPT charger can be a lot better at charging has to do with a lot of factors relating to the amount of sunlight the panels receive as well as the panel voltage.

In short, the MPPT charger is simply able to draw in a lot more solar energy. They are capable of converting all of the additional solar energy into voltage. And it is because of the immense efficiency of the charger that the price for this device can be a whole lot more expensive than the PWM option while it will also mean that the MPPT charger ensures that the battery being charged will have a longer lifespan.

A Word on Choosing which Solar Charger to Buy

Ultimately, the solar charger that you will end up buying will be the one that is best suited to the rest of the system that you are planning to have installed. This means that you should aim to work with a company that can provide you with the right advice and the right equipment. The last thing that you should want to have to deal with is a system that doesn’t meet your expectations.

You should also be sure that you have done full research into the various brands that you have available to you. You should also not forget to have a good look at all of the solar charger prices, as you will find that there is sometimes a great difference between the various options.
