To prevent your batteries from being overcharged by a solar power system, a solar charger controller (sometimes referred to as a solar regulator or MPPT charge controller) must be used.
There are two main solar charge controller types available – these are PWM (Pulsed Width Modulation) and MPPT (Maximum Power Point Tracker). PWM and MPPT refer to the way the controller regulates the charge from the sun to the batteries.
PWM is the original method and has been around for many years, whilst MPPT is a newer and more efficient method. MPPT has been specifically
designed to reduce the efficiency loss in charging batteries from solar panels.
