I priced out a proper generator, one that could run for a couple of weeks in case of catastrophic grid failure. After adding a 1000 gallon propane tank on an engineered concrete pad, installation, permits, maintenance, and propane itself then subtracting the Powerwall federal tax rebate, the prices were similar. I'd also need propane deliveries after 2-3 weeks on a 1000 gallon tank. Who knows how well that will go. There are several old bridges between me and the highway, and a even if they're intact after a quake, are they going to be intact enough for a 30,000 lbs propane truck?
The big advantage of the propane generator is the ability to charge the EV or EVs, but then if I'm off grid, I'll charge somewhere else.
