WHAT IS A SOLAR CHARGE CONTROLLER?

A solar charge controller is used to keep the battery from overcharging by regulating the voltage and current coming from the solar panel to the battery.
Solar charge controllers are an essential element of any solar electric panel system. At a most basic level, charge controllers prevent batteries from being overcharged and prevent the batteries from discharging through the solar panel array at night.
