Modern RV appliances and appliances optimized for solar battery banks have a “soft start” in order to minimize the startup draw, so your numbers are off in that regard.

I took the numbers off the Ramsond RV air conditioner website, which I linked. So what's wrong about them? Only thing I guessed about was the length of time for startup. I'll even stipulate NO startup time. You still only get a little more than 16 hours.

Variable speed compressor, they don’t have it. They may be new units but they’re old tech.
