Solar Charge Controllers SOLAR CHARGE CONTROLLER is at the heart of every solar system, and is required to monitor and control the power going into and coming out of the battery. It must also manage the power generated by the solar panel to ensure it does not overcharge the battery. The charge controller must also ensure that the connected loads don’t over-discharge the battery, thereby damaging it.   We provide a wide range of Charge Controllers from 5A upto 200A in various DC Voltages.
