The main function of a charge controller (also known as a charge regulator or battery regulator) is to safely charge a solar battery at the correct charge rates, and to protect the battery from overcharging.
ECO-WORTHY offers two models, the more advanced Maximum Power Point Tracking (MPPT) and the industry-standard Pulse Width Modulation (PWM) controllers for solar-battery charging, suitable for both 12V and 24V solar kits.
