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. Most "12 volt" panels put out about 16 to 20 volts, so if there is no regulation the batteries will be damaged from overcharging.
Most people don''t know that the output of solar panels varies widely depending on the weather and the angle of solar installation. the controller controller current must match to the lowerest amps of solar panels, This means that your solar charge controller will need to handle up to 25A of current, or more.
