What is a Solar Charge Controller and PWM means?

A solar 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 batteries. E.g., "12 volt" panels output vmp volts is about 16 to 20 volts, so if there is no regulation the batteries will be damaged from overcharging. Most batteries need around 14 to 14.5 volts to get fully charged. The charge controller regulates this 16 to 20 volts output of the panel down to what the battery needs at the time.
