Most battery charging units fall within the 12-48VDC range. These are sometimes more suitable for those looking to devise simple systems to power solar lanterns in a garden or a mobile device. However, we’ve also included a few PWM controllers as high-quality options. MPPT controllers are widely accepted as the best of the best, so they inherently top our list.
The type of the solar charge controller refers to whether it’s an MPPT or PMW model. How We Ranked the Best Solar Charge Controllers Type Each type serves its own purpose, but ultimately the MPPT controllers are more commonly used. There are two main types of solar charge controllers: Maximum Power Point Tracking (MPPT) and Pulse Width Modulation (PWM). If there’s no regulation, the batteries can be easily damaged, which will cost you money and time to fix. It’s important to use a charge controller as it improves the efficiency of a solar-powered system by up to 50%, can prevent the batteries from being overcharged, and will extend the battery’s life when used correctly. To put it simply, a solar charge controller regulates the power that’s transferred from a solar panel to a battery.
