pitch,
To run a single AC unit without a generator, from solar, it makes sense to go to 24 or even better a 48 volt battery bank.
Here is a list of what would be needed:
DC 48 to dc 12 volt converter
2000 watts of panels
8 100 amp-hour batteries split into two banks (SiO2 if cold) or LI if it is warm)
48 volt to 120 volt ac hybrid inverter/charger with load support.
two 80 amp charge MPPT controllers
A remote start 3400 watt inverter generator for back up.
I'm sure I missed some items.
If I were doing it, I'd keep all the technology from one company such as Victron or Outback. That ought to minimize the problems of "play well together".
I find it odd that the cheapest part is the solar panels.
While it could be done, it would take a heck of a long time for payback.
