Generally, smaller UPS units are not a good fit for that type of load. And, you want to make sure that you get a UPS that does a true sine wave output since the approximated sine wave output of this UPS would not work well with many non-computer loads. APC states: One potential issue is the inrush current draw for a motor. It can easily overload a Back-UPS UPS model. Secondly, these models of UPSs output a stepped approximated sine wave when on battery. This waveshape, while ideal for computer type equipment, is not particularly compatible with most motor loads. The result may be that motors run very slowly, erratically, or not at all when the UPS is on battery. My general rule is that you want to get a UPS with the right type of output and generally at least 2X the running load of the motor to be safe. One sump pump that I just looked at was 120V with a 9.7A running draw, which is 1,164W, so I would say at least 2500VA so that it can handle the startup load. And a 3000VA UPS will only give you 15 minutes with a 1200W load on it. Extra battery units would give you around 30 minutes more each. You can see more on the approximate running times in this APC chart: https://www.apcguard.com/Runtime-Chart-for-Smart-UPS-XL.asp
Sorry, there was a problem. Please try again later.I believe the question is for how long. You will have to look at the power consumption of your sump pump in its specs. The manual for the UPS provides a guide of how long it will maintain different power consumption equipments plugged in the battery side based on total power consumption. Total power consumption should not exceed the capacity of the UPS.
Sorry, there was a problem. Please try again later.I am sure it can be used BUT I wouldn't count on it to last but a few minutes because of the power a sump pump can draw.
Sorry, there was a problem. Please try again later.You could use this for a Sump Pump however it would be for a relatively short period of time compared to a full-size deep cycle marine battery used by units intended for sump pumps like the Basement Watchdog. I have used one of these units like you suggest, but after the emergency passed I invested in the specialized unit I mentioned. I compared the function of the two and the specialized unit ran the sump pump for 2 days longer than the APC UPS.
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 like a sump pump. 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.
Sorry, there was a problem. Please try again later.Your best bet is to get a generator. This has a battery and if you use it where it is wet you might die.
