If you want the battery bank for grid independence, it’ll do that

We have a little battery (1200Wh) that will run the refrigerator overnight, so if a storm is on the way we set that in-line incase the power goes out, don't worry about the freezer - we can get the gasoline generator cranked up in the morning if needed. They call it a generator, it's as heavy as a generator, but only outputs the power that you get from about 8 ounces of gasoline before it's needing a recharge.
