  What is a charge controller? A solar charge controller is a regulator for your solar battery that prevents it from overcharging. Batteries are rated for a certain voltage, and exceeding that voltage can lead to permanent battery damage.   Types of solar charge controllers There are two types of charge controllers to consider: Pulse Width Modulation (PWM) controllers and Maximum Power Point Tracking (MPPT) controllers. PWM controllers are generally less expensive and can only be used for smaller systems where the voltage of your solar...
