The 10A 12V/24V Auto Switch&nbsp;PWM Solar Panel Battery Regulator Charge Controller is designed to always keep the battery on fill voltage condition, preventing battery from over-charging, over-discharging and reverse charging. Compared with solar charge controllers that are commonly seen on the market, this PWM controller can increase efficiency by 10%-30%. It can charge and discharge at the same time. What’s more, it has perfect SOC function, supports charge current control and offers power control to the loads.
