Buying Guide to Get a Sump Pump Power Inverter

Before you buy an inverter, you should know that this device is a crucial bit of machine that will control the frequency of the incoming current flow and provide power for other devices. So you must keep note of some important factors that make up a good power inverter. Let’s take a look at some important considerations.

Size matters (in terms of power)

You have to keep in mind that your sump pump needs quite a bit of power to be functioning. Always pick an inverter that has substantial surge power, because the continuous power will be speaking to the surge unit when transferring the water out of the sump pit. Always select an inverter with double surge power compared to the Amp-hour of the battery being used.

Variants of power

You must know what is a pure sine power and a modified power. Pure sine power is desirable and recommended when powering a sump pump because it produces a clean smooth power boost to the pump in an adequate manner. 


For any electronic items, machines, we always look for durable products, the same goes for power inverters. Always try to find out the tailormade units that are built to last longer rather than units that need to be changed too often. Invest in something sturdy, for example, the Krieger inverter mentioned above.


The aspects of power inverters must not be overlooked. You must look for an inverter that boasts all the necessary qualities to be termed the best power inverter for sump pump. Look for features like the durability of the inverter.

The continuous power to peak power, the capability to withstand short circuits, fluctuating voltages, temperatures, fast charging unit, etc. It’s better if your inverter has an LCD panel that will let you know what’s cooking inside. Also look for flexible features like remote controls, external battery units, outputs, etc.


Inverters are costly if you look at the pump sentry version I mentioned in this write-up. If you look at the Tripp Lite you will say that inverters are budget-friendly. It depends on what you can afford. Numerous power inverters do an extremely good job being on the affordable list, and some inverters serve the best outcome but are expensive. Pick something that compliments your budget.

What size power inverter do I need to run a sump pump?

If you are using a ½ Horsepower sump pump, you can easily power it up with a 1000W power inverter. It is important to have good surge power for the inverter because running power will escalate to the surge power to successfully draw the water out. Make sure the peak power is 2 times the amp size of the pump.

Can a car inverter run a sump pump?

Car inverters are made to power electronic devices in a car, like the LCD, rpm, etc. Using a car inverter to power up a sump pump is not a good choice because sump pumps use peak power to manage the excessive water out from the pit, so it’s better to use an inverter that has sufficient surge power.

How long will a 12v battery run a sump pump?

If the battery is 12V with a rating of 100 Amp-hour, it will run a 1000W sump pump for about 45 minutes similarly a low wattage pump like 700W-800W will run for 1 hour with a 12V battery.

Final Verdict

If you ask me, I would suggest you pick a power inverter like the Raybend Sump pump backup power system or the Tripp Lite power inverter.
