As an off gridder and certified PV installer, I absolutely LOVE these charge controllers.I use them to charge batteries to power pumps, lighting, utility fans, maintain parked vehicles, etcWork great with up to a 250watt module. Even equipped with dual USB for charging mobile devices and the 5amp load with switch is fantastic for a light.I have some in operation for 3-5years now. Appx 8 around the property all providing point of use power.
