In California, you can purchase a 14.3 kWh battery for $3,500, which qualifies for a $2,500 SGIP rebate from the state plus a 30% federal rebate. I find this concept interesting, but the cost is quite high considering it’s literally hundreds of dollars less money to just get a 14.3 kWh battery.
You will still need a (hybrid) inverter to use it so add at least $500 on top of that. And that money doesn't really get you a unit which is capable enough to really make use of a battery of this size.
