VS-AU Series(10~60A) PWM Solar Charge Controller
The VS-AU series is a PWM charge controller with LCD display and two USB ports. In the case that the difference between the working voltage of the solar panel and the battery voltage is not large, choosing this PWM series is equally reliable, but it is more cost-effective. Widely used in rural electrification, household electricity system, etc.
