Most of the Window AC unit would use 500W or more when it's running.
You will need an inverter that can put out at least 1500W to be able to start the AC.
I'd say get a 2000W inverter just to be safe.
And this system in the best AZ, USA weather would only put out 400W. But AC drains 500W.
You are at -100W per hour. This will drain your battery from 14.4V down to 10.6V and then inverter shuts off.
I would get about 2000W in solar panels + 2000W pure sine wave inverter + MPPT Solar charger controller + four 12.8V 100AH LFP batteries kit to run a 500W AC for about 10 hours (10AM- 8PM) a day.
If the weather is not sunny and solar panels can't produce enough energy, then I would only turn AC on from 11AM to 2PM to save the energy.
So just double it. Unless you going to mount this somewhere that had no trees for at all.
Possibly 800w per day. Honestly, to the biggest size you can move around.

Would it be better to set up these solar panels and feed it back to the grid for some payback?

And even if it's not breaking any law at where you live, when you feed it back to grid, the power company may charge you based on a per KWH if you have one of the old school non-digital meter.
If you want to skip all the required paper work, then go off grid and add the battery into the system.
The way how I see it is this, my power company charges me $0.2 per KWH.
Based on the projected KWH that I would use in the next 5 years, if a system breaks even within 5 years, I'd say it's a slick deal. After 5 years, every KWH from the system will be like free; like $0.00 per KWH. I also expect the system to fail after x number of years.
