I have been thinking lately about what it might take to run a small house entirely off grid. My thought was that if you could build a separate battery shed that is away from everything and then fill it with like 100 kWh of batteries charged by a 30 kW solar array, then you could presumably run power from the battery shed to your house as if it was a normal utility hookup. But then again I have no clue if a town zoning office or building inspector would have a fit over a setup like that.

The easiest is usually to have wheels on the house, and then power it as a trailer/rv.

I am thinking more something that has a high spouse approval factor. 1200 sqft, 2-3 bedrooms, normal plumbing and sensible HVAC.

I’m thinking something that is technically a large RV trailer “docked” into a non-house structure that provides additional space.

All major plumbing and appliances and power are in the trailer, the extra “rooms” have nothing much but lighting.

Not sure how it’d work in practice.

Powering your house is an advertised feature (with additional equipment) of a few electric cars.

e.g. https://electrek.co/2025/09/28/yes-an-ev-really-can-power-yo...

To go off grid, you'd need a source of power to the car that wasn't your house.
