Su-Kam’s Solar Charge Controller is a system advanced MOSFET based PWM Technology. The term “charge controller” refers to a device that charge the battery from solar panel.

Working Principle

The controller is for off-grid solar systems. This protects the battery from getting over charged using the solar modules and over discharged by the loads. The charging process has been optimized for long battery life and improved system performance.

The comprehensive self-diagnostics and electronic protection functions prevent functions prevent damage from installation mistakes or system faults.
