I have 18kw of solar and 30kwh of batteries with a 5ton ac it will run it will run indefinitely assuming the sun comes out, if it doesn’t I have a chargeverter that can keep the batteries charged off my RV’s diesel generator or gas portable.

My solar system generates excess power daily and has zero maintenance, the generators are pure money sinks for backup power and require regular maintenance.

Options are nice.

Also heat pump water heater and dryer help reduce load along with efficient variable speed hvac and good insulation.

Fuel is a problem during a storm too and a buried large propane tank is a good way to go but very expensive on top of installation.

An electric car with bi directional charging would add to flexibility either charging from home system or being able to go find power and bring it home.

Ideally I would like a gasoline hybrid with power out like a F150 power boost and a fully electric with large battery and V2L any Tesla would do now as they all have 2400w out I believe Cybertruck can do more. My chargeverter can take 120v or 240v
