ATS upgrades off-grid solar, wind or hydro generator system, bringing you with uninterrupted power in cloudy, rainy, windless days or winters, or when main battery pack of your RV or boat get problem. -- It connects solar-inverters and public power/generator in the same circuit. -- Acts as Opposite UPS: battery power priority, public power second -- It transfer according to battery voltage. * When voltage of main battery runs down, ATS automatically switchs loads to public power/generator/standby battery within 10ms. (Protect batteries from over discharging, extend batteries' life.) * When voltage of main battery recovers, ATS automatically switchs loads back to the main battery circuit. (Totally trouble-free operation) -- Fast Change-over: Inverter transfer to public power ≤ 10ms, public power/generator transfer to inverter ≤ 16ms. No power "flickering", loads work all times as if no power change. So you never get stranded. It cuts your electricity bill by at least 30% by just setup a small DIY solar array instead of spending $34k for a grid-tie system. Utilize solar power and rely less on the public power company. Easy Installation. DIY. No need to cut into public power, or any factory wiring that may void the manufacturer's warranty of your boat or vehicle.
