EcoFlow PowerOcean Battery Review: Cutting My Bill in Half

A home battery is like a giant power bank for your house, and there are several reasons you might want one. Maybe you want to store excess power from your solar panels or guard against outages. Or maybe you want to truly pull the plug and go off-grid. For me, I wanted to buy power at my cheap overnight EV charging rate and use it during the day when it’s usually four times more expensive.

I had an EcoFlow PowerOcean home battery installed two months ago, and I’m mostly pleased with how it’s working, but I’ll share my experience and run through the pros and cons for you here, including how the math adds up in saving me money in the long run.

Preparation and Installation

There are a few things to think about before you install a home battery. I have an in-depth guide to this in the works, so I’ll just quickly run through the basics here. You'll want to check your electricity usage over the last few years to help you figure out how much power you need. If you have solar panels or intend to get some, you need a hybrid inverter to convert the DC electricity produced by your solar panels into AC electricity you can use in your home. The inverter also manages when your home is powered by solar, battery, or the grid.
