You could just create battery trailer to power your house and drive to the next Tesla charging station with it whenever it runs low. No need for power lines or any power generation in your backyard. Maybe someone should propose that trailer idea to Elon? Tesla already produces everything necessary to take yourself of the grid, it only needs to be bundled up right.

No need for a trailer, since a typical EV already has more capacity than most home battery solutions. Example: A 2021 Tesla Model 3 Long Range AWD stores 82 kWh[0], while a PowerWall 2 only stores 13.5 kWh[1]. So a single Model 3 is the equivalent of up to 6 PowerWalls. All it's missing is official support for vehicle-to-grid connections.
