Am curious as to what expense you expect.
I had looked at some units in the 4.5 kw range @ 100 volts
wind turbineThey recommended a 2000 amp/hr battery bank, and the cost would end up over $6k.
And that from my numbers would only cut my electric usage at home by about $70 a month where I live.
I know it's different and has a different value when working with a remote location , but to gain AC usage, I would think your going to come up short. With the system I mentioned and adding 500 to 700 watts of solar, and maybe even switching to a high efficiency mini split system in the 12,000 btuh range it may work.
Mini splitThis unit would still require 13.5 amps at 120 vac to start, but is very low amps while running.
At least the hottest days would be getting the benefit of the solar assist on power.
Good luck on your efforts
