Every US household has at least some big circuits across both lives. You could theoretically put the battery in the laundry room and use the 240v outlet. This is effectively what I did when my power was out during a hurricane. I backfed my entire house through my laundry room. Not to code but nothing was that week. The circuit wasn't rated for enough to handle the HVAC load so I eventually installed a separate 50A inlet on the side of the house.

Not really. My parents have all natural gas for the furnance, oven, stove, clothes dryer, and water heater; no air conditioner. Everything else is lights and outlets. There are no 240v outlets and no 240v breakers other than the main breaker.
