The VS-AU series charger controller is a PWM charge controller with an LCD display and two USB ports. When the voltage difference between the solar panel operating voltage and the battery voltage is not significant, choosing this PWM series is a reliable yet more economical solution. It is widely used in agricultural power supply and residential energy systems.
