There are lots of resources available for the clever. You can back feed your house from a high current line and jump both sides of the 220vac. This will effectively make your house wiring into a big extension cord. All that is required is all 220vac breakers and the main need to be opened and all high current loads be shut off or disconnected. I run a refrigerator and furnace with a 3000-watt inverter generator. I have excess power available any location for lighting. All the low current devices, cable and internet work.
The generator will run 20 hours/tank. I keep 5 gallons of rec fuel in a steel container through the winter months. In the summer months the generator is used for the RV.
Make sure that you test the system in real conditions. Night during a blizzard would be a good time to stress the system.
