This is already a thing, with Tesla Powerwalls, 13.5 kWh home batteries.

Owners of Tesla’s Powerwall can now re-sell their stored electricity back to California’s grid as part of the Virtual Power Plant program, Benzinga reports. The program is being piloted right now in partnership with PG&E for Northern Californians, and it recently expanded south in a partnership with Southern California Edison.
The result of these thousands of Tesla Powerwalls essentially creates a giant distributed battery that can be drawn upon in times of peak power usage, or high demand during heatwaves or other extreme weather events.

The Tesla system along with their solar roof and the car creates a cool ecosystem, where it's all auto controlled and the solar can power your house if it's sufficient, the grid can keep the batteries topped off if there's impending weather, the house can draw from the car, draw from the batteries at peak usage times in markets that have variable rates, the batteries can send back to the grid, etc.
