Solar charge controller, charge regulator, or battery regulator limits the rate at which EC is added to or drawn from electric batteries. It prevents overcharging and may protect against over-voltage, which can reduce battery performance. It may also prevent completely from 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.
1. MICROTEK SOLAR CHARGE CONTROLLER SMU 30 AMPS, 12 VOLT
Microtek solar charge controller is suitable for low-power applications. It used to charge batteries from solar panels installed on the roof. The micro-controller in the Microtek Solar charge controller senses the battery’s full-charge voltage and it stops the flow of energy when the battery reached full charge status. and when the battery charge level drops it starts the flow of energy to charge the battery.
