> Thier max output is only 9.6kW so it can’t do a whole home backup and the car can only run in backup mode when the grid is out.

9.6kW should be enough to backup your entire house, that's 87A... Lots of people only have a 100A supply in general. Depending on your setup you may have to limit what you use at one time but even in a large house that will be more than enough for AC, lights and electronic devices.

9.6kW is 40A at 240V, and a 240V 100A single-phase residential service is 24kW.

Still, 9.6kW should be more than enough to run a fridge, lights, receptacles, sump pump, a 2-3 ton A/C unit, and a furnace fan. It would be challenging to impossible to back up a home with electric (resistive) furnace and electric (resistive) water heater with only 9.6kW.

That’s peak production, without battery storage the fluctuation during the year will likely be too much to keep the “lights on”. Would be cool to have a smart home that prioritizes the electricity supply to different systems based on how much is available.
