#Voltage on battery backup for sump pump install

If you're in an area that often gets serious storms, you might want a bigger battery, a second battery, or even a small generator.īut what if you're not at home to switch the power? Tyson's suggestion of adding a battery powered pump will, at a minimum, buy you some some time to get there and switch things if necessary. Your 110 AH battery should power the pump for around 3 hours until it ages, given that the pump cycles on and off. If there are many power lines down, it can be a lot longer than that. If a crew needs to be dispatched to fix a downed power line, it could easily be hours. Some causes can be corrected within a few minutes. Look at the history of how long power stays out when it goes out. If we did lose power, I was planning on unplugging the sump pump from the outlet and plugging it into the inverter that was being powered by the marine deep cycle battery. I was looking at power inverters and I was wondering would a 1000 watt power inverter be enough power? I heard that when sump pumps first turn on they use more power than their continuous operating level.ĮDIT- I was planning on keeping the sump pump plugged in to an outlet unless we lose power. I was looking at the sump pump and saw that it should take 920 watts when it is operating and I calculated that by multiplying 8 amps at 115 volts which is what the cap on the top of the sump pump says.

I already have a 110 amp hour marine deep cycle battery which powers a 60 foot pound electric trolling motor for at least 4 hours so I believe that a sump pump should be able to be powered by this deep cycle battery.

I recently lost power during a rain storm and had to pump water out by hand until power was restored so I am looking to install a battery backup for the sump pump. I currently have a sump pump in my basement.
