WHAT IS A SOLAR CHARGE CONTROLLER? A charge controller, charge regulator or battery regulator limits the rate at which electric current is added to or drawn from batteries. It prevents overcharging and may prevent against over-voltage, which can reduce battery performance or lifespan, and may pose a safety risk. It may also prevent completely draining ("deep discharging") a battery, or perform controlled discharges, depending on the battery technology, to protect battery life.The terms "charge controller" or "charge regulator" may refer to either a stand-alone device, or to control circuitry integrated within a battery pack, battery-powered device, or battery recharger.
