A charge controller or regulator prevents overcharging by limiting the current flowing into the batteries. The key to extending battery life in a solar system is to protect batteries from a complete discharge / overcharge. A charge controller is a power system component whose functions include regulation of solar charge current and in some cases to provide low battery protection.
