It works fine but there is a delay that lasts long enough for a pc or tv to turn off.

It wouldn’t transfer the source power to the load. The battery side worked ok but not the supply side. Probably a fault on the board, disappointing.

I bought this for a small solar, battery and inverter setup. The system operates one room in my house. The laundry room. But if the washer is ran excessively and it has been cloudy days. The inverter will shut down. This automatic switch with switch the room back to line power from the breaker box. So fast that the lights and washing machine don't even show a loss of power to the naked eye. Simple but very useful. 6 months now and still working perfectly.

I use this automatic transfer switch (ATS) for my 200 W solar panel system to switch between TWO incoming powers 120VAC to drive 120VAC/60W pond pump.1/ The “Main Power Supply” terminal, I wired to 120AC power inverter from solar panel.2/The “Backup Power Supply” terminal, I wired to 120VAC electric power grid.I set the timer for solar invert RUN 10 hours/day from 7AM to 5PM to keep my Battery not dropped below 12VDC.At 5PM every day, when the timer cuts off the incoming solar power, the inverter will lost the power, then, the ATS will transfer to electric power grid to continue running the pump.At 7AM every day, when the power inverter is energized, the ATS will transfer back to power from solar panel.
