Why do I need a Solar Charge Controller?
A Solar charge controllers or regulator, regulate the battery charge to ensure that batteries are not overcharged. Limits the rate of electric current added or drawn from batteries. It prevents overcharging and may protect against over-voltage, which can reduce battery performance or lifespan, and may pose a safety risk. May also prevent completely draining (“deep discharging”) a battery, or perform controlled discharges, depending on the battery technology, to protect battery life. 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 charger.
