Will it work on a 1/2HP sump pump null

I seriously doubt it. A motor has a large staring current, and would very likely overload the UPS on startup.

This is probably not a good choice for a 1/2 HP sump pump. A pump like that probably takes about a 1,000 watts to run and about 2,000 watts to start. You probably want a bigger UPS.

Those things take a lot of juice. You'd be better with a low powered generator.

It should. They don't draw too many amps...

Thank you for your inquiry. Unfortunately we don't recommend using our BackUPS units with a motorized load. One potential issue is the inrush current draw for a motor can easily overload a BackUPS unit. BackUPS are ideal for computer equipment and may result in the erratic behavior when connected to a motor. To protect this type of equipment, APC recommends first determining the appropriate size UPS for the motor load in question and ensure the UPS is large enough to handle the start-up inrush current draw of the motor. Secondly, select a UPS which outputs a pure sine wave when on battery, such as a Smart-UPS.
