Best Charge Controller Brands

What Is A Charge Controller?

A solar charge controller is a voltage and/or current regulator that keeps the batteries in a solar panel-battery-inverter system from overcharging. A charge controller may be a stand-alone device which has to be bought and installed separately or it may be a control circuitry integrated within a battery pack, a battery-powered device or a charger. When bought as a standalone device, which is the case in most installations, it is often installed between the panels and batteries. A very important part of the system, they prevent the overcharging of batteries by limiting the amount and rate of charge of electricity from the solar panels to the batteries. They also prevent battery drainage by shutting down the system if stored power falls below the specified depth of discharge, mostly 50%.
