Generally a propane generator is a wiser, more reliable backup option. Propane doesn't go bad, and in disaster scenarios often the sun isn't shining or your solar panels could be damaged. Solar + battery is a good system when the weather is good and everything is going well, but for a fallback system a propane generator can't be beat.

Yeah, this is where I landed, too. Except propane bottles only get me about 3-4 hours per bottle and it's pricey. It ran $50 for one day of AC during the last outage.

I just bought a kit to convert to natural gas though. Most people who've done it are happy to not change bottles all the time. It won't help after an earthquake but the regular PSPS outages I get make natural gas a better fit for the moment.

I'm running an EG4 system with a decent amount of battery storage. I have a generator port on it that makes it easy to plug in a portable generator to assist the PV and charge the battery. It's really easy for me to roll my generator over and run it a few hours a day to supplement the solar. Even a cheap 5kW generator is plenty because it doesn't need to power the house, just provide a continuous charge to the batteries.

I'm looking into getting a large EV so I can move off of a propane generator. A generator needs service, it will cut power for 5-10 seconds while it starts up (so your PCs and whatnot will power cycle), and it's loud.

Wouldn’t a diesel or gasoline generator be better? You can carry both in a bucket found on the side of the road which isn’t possible with propane.
