Metmom- an inverter on your car doesn’t have the “oomph” to power your home.
The big batteries in an electric vehicle can supply upwards of 75 kWh of power at 20-30 amps continuous, and it’s pure sine wave with few harmonics, ie clean power, and lots of it.
Your car is probably not able to power much of an inverter via the accessory plug/cigarette lighter. And if you attach a more powerful inverter to the battery, consult an automotive electrician so you don’t overload the battery/ alternator.
Larger vehicles with 2 batteries or larger batteries can power large inverters, but even they cant compare to what an EV can do. At least one designed to do it like the Ford Lightning.
Go to tractor supply and get yourself a dual fuel generator (burn propane). It’ll work better and use less fuel than idling your vehicle to run an inverter.
I know that.
The point is, that electric cars are not the only cars that can do that.
Besides, all you really need to run are just a few basics, like the furnace.
And the rest of your post, you’re preaching to the choir.
