Why is living off the grid the main objective here? I live in a suburban area that occasionally has power outages. Right now I'm considering the purchase of whole house generator but if I could have a battery instead I'd do it.

You can have a battery instead. You can get a battery right now; lead-acid will work just fine, if we're talking power outages of an hour or less.

House-sized UPS systems are a thing. An expensive thing, mind you, though I don't know how expensive.

Yeah, I looked into that and last I checked it is prohibitively expensive. If this is a viable alternative I can see two great uses.

1.) Whole house UPS 2.) A way to take advantage of significantly lower night time electric rates.
