Things to Consider when Purchasing a Power Inverter for Sump Pump

Before you can spend your hard-earned cash on a new power inverter for the sump pump, there are a couple of things that should be at your fingertips.

Power inverters are everywhere, and you should not take some of the vendor promises at face value. Most of them tend to sugarcoat, and that can lead to significant disappointment in the end.

Size of the Inverter

You must get an inverter that is big enough for a sump pump. Typically, the basis for the rating of sump pumps is on the power they draw.

Keep in mind that the AC uses a much higher current, usually double as much. To be on the safe side, always incorporate this surge capacity so that you are aware of what you’re working with.

For illustration, if you have a 5 amp pump, then you can safely assume that ten amps are the surge current. The surge rating and the continuous wattage rating will always be higher in most of the inverters on the market.

Unfortunately, that is not always the case, especially for models that cost as little as pocket change. They may only surge a fraction before cutting out, and that is not always sufficient.

Ideally, the continuous rating should be equal to or greater than your pump’s surge current draw.


The safety of the inverter is as important as its quality. It doesn’t hurt to take extra steps to ensure that the charger is safe and efficient. Dig deep into their customer reviews and other information that you can lay your hands on.


The portability of the inverter mostly depends on how you will be using it. In this case, portability may not be so crucial because you will be using it on the sump pump.

Of course, the sump pump is localized and will not be going anywhere. It will be a different case if you are talking about an RV or something like that.

Budget and Warranty

No kidding, the best inverter charger is a little bit expensive. Don’t expect to chuck out pocket change on a decent-quality power inverter.

But that does not imply you should spend an arm and leg to get the best. Check the above to guide you in the right direction. Also, make sure that the inverter has a decent warranty to safeguard your investment.

The best power inverter for sump pump ensures that your basement is always dry, even when there is a power outage. You don’t have to worry the next time that a storm comes, and the power goes if you have a decent power inverter like the listed above.
