Air conditioning is incredibly power-hungry when powered from an inverter. My solar experience is with an RV, but even with that lower-powered AC unit, you can realistically expect only 30-60 minutes with the batteries an RV can carry. A house won’t have the same space or weight restrictions, but that doesn’t make them any cheaper. FLA batteries are the least expensive currently available, and I’d ballpark it at around $4000 in batteries alone to get a few hours of air conditioner.

An alternative to this is to have a generator that works with either propane or car-gas.

Are those lead batteries or lithium? A lithium battery pack is about 10 times lighter, and 2-3 times smaller, than a lead battery pack that can store the same energy.
