A charge controller, or charge regulator, is basically a voltage and/or current regulator to keep batteries from overcharging. It regulates the voltage and current coming from the solar panels going to the battery.

Solar Charge Controllers are extremely important on any large scale project. But they are also very important on smaller systems that are over 10-15 watts as they remove the risk of accidentally overcharging your batteries and provide ideal charging conditions by regulating the voltage swings coming off of the solar panels. There are two types of controllers available the first being Pulse Width Modulated or PWM and the newer ultra efficient type being maximum power point tracking or MPPT controllers.
