They aren't. your just looking at the name brands that want to sell you a "Solution"

This is around 5Kwh for $1300. They even sell a rack that holds 5 of these. You can have more than one rack hooked up to your inverter)

30kWh for $8k here

I'm not sure if I would classify that as a home battery, but it does indeed seem much more reasonably priced. I don't know if I can find a local installer selling this or anything else in the same price/kWh category.

With inverters and solar panels I don't have this problem.

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.
