Batteries/Charger Controllers

“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 batteries need around 14 to 14.5 volts to get fully charged.

There are three types of charge controllers: the basic charge controller using voltage regulator, Pulse Width Modulation (PWM) based and the Maximum Power Point Tracking (MPPT) based charge controllers. Each charge controller works best for a set of parameters.”
