which product can I use to power my sump pump Want to have 4-8 hours of run time for my 1/3 HP pump.

Question

This would be controlled by the amount of times your pump kicks on during that period. That would vary based upon the water table in your area and rainfall. There are DC sump pumps available that will run on a wet cell (car 12volt) battery. That would be a more efficient way to handle your requirement. The pump would always run off the battery and you would use a car battery charger to keep the battery "topped off" and to recharge it fairly quickly if you do run from the battery for a long period of time. If you are subject to frequent, extended outages you might want to consider a deep cycle, marine battery.

I would not use these for a sump pump. I tried that years ago and the draw was to great and it blew the circuit in the battery unit leaving the pump off and flooding my basement. They make higher powered units for designed for pumps.

get a generator

DPitty · Answer

You should be looking at a small commercial Liebert or Emerson UPS system for something pulling anything over 30-90 amps for this period of time.

To answer that question, you need to know how many watts your sump pump uses.

frrrosty · Answer

That depends on the load, as in wattage. I have used many BBU's, and I don't know of any that would provide power for that long a time with what I assume is a considerable load. This particular unit will run a high-end PC for about 10-15 mins. max on battery alone.
The best strategy would be to have an emergency generator that would kick in automatically, while the battery backup would keep the pump running for the few seconds it takes the generator to kick in.

SteveO · Answer

These type of devices are made for low power electronic equipment and would not work with a motor in a sump pump. There are other devices from other manufacturers that use car batteries and an inverter to provide hours of standby AC power. Do a Google search for these terms. Good luck.

Mark · Answer

to power a sump pump you need a small gas generator. this will not do it.

MovieMadam · Answer

Sump pumps take some power when in use so I would go with long lasting hours of coverage. Your best bet is to ask the installer of the sump pump what you need. They tend to over price what they would sell you but you could use the information they provide you with to take to the store and buy the size you need at a better price.

Unless that pump is amazingly efficient you probably don't want to go this route due to cost... With that being said, you will need to know the wattage of the pump during start-up (if there is a spike needed to start it), the running draw, and roughly what percentage of the time it actually runs. APC/Schneider offers a selector to find a product based on that info here:
