They are literally used as home batteries for many people that currently live off-grid. Yes, you would need an inverter as well. Just like you would for any kind of device to store 120V/240V AC power as 12/24/48V DC power. (Both that site I linked to and the other poster have lots and lots of inverters that can be tied to grid, and solar, and carey enough power to run your entire home for < $2k

I wouldn't call off-grid a typical home situation either, it's just something that is not done here. I mean I can go to any local installer and get solar panels and inverters that are reasonably priced, but with batteries that's just not the case.
