Genasun 10A MPPT Solar Charge Controller for Lead Acid Batteries


So you paid for a 140 Watts solar panel, and now you want to get your money’s worth. The GV-10 extracts more power from any given panel than a PWM or other MPPT controllers. PWMs may offer a lower controller cost, the GV-10 MPPT controller delivers more power reducing the cost per watt by 10-30%. The GV-10 is the ultra-high-speed MPPT solar controller.
