This is not the UPS for you. I'm not an APC representative, but this unit is only rated for 865 Watts. A 1/2 horse motor is rated for about 650 Watts with surge wattage of 1800. If you get a load over 865 Watts, the UPS may shut down. At 650 Watts, you're unlikely to get more than 10 minutes of run time.
Sorry, there was a problem. Please try again later.Your pump takes 22 amps start up and at least 12 amps when running. 12 amps at 120 v is 1440 watts. http://www.apc.com/tools/ups_selector/pso/zones/by_load.cfm?location_type=home Not going to get that kind of output from a standard ups. Suggest automatic generator fail over system
Sorry, there was a problem. Please try again later.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. Also that load would only provide you with around 14 minutes of runtime when the UPS goes to battery.
