I think what's driving a lot of the questions is not knowing how much instantaneous power (and startup current) your AC uses when it's on. 80kWh/day is only 3.3kW avg, but assuming most of that is your AC (with 30% duty cycle) and it seems your system is at most oversized by a factor of 2. There is a 22kW model in the same product line, so presumably you had a good reason to go with the next one up.

Given that Texas's electricity problems involved a problem with the natural gas supply, are you not worried about that going out as well? I just got a generator, but aimed for a small one that would be more efficient so that I would need to store less fuel. Although I still need to figure out some solution for intelligent load management so that I can run (fridge,freezer,boiler,etc) sequentially rather than simultaneously.
