You'll be running a generator all day or carrying 1,000 lbs of battery which would take all day/night to charge. I would go with a Honda inverter gennie to run things by day and keep a battery bank charged for night use of the small loads. A fridge is likely not a small load though unless it's something meant for off grid.
We lived off grid for 4 years on a 500 watt 12vdc solar panel system using four golf cart batteries with a chinese Enkle knockoff 12 vdc fridge. Did ok with it but AC without a huge battery bank or gennie running ain't gonna happen.
I would give you a link to a calculator for this sort of thing but we searches have become 100% useless in recent years.
I have been living off grid on wind and solar for 25 years. And I agree with Pollard, the A/C is a problem child. Everything else you can get away with a minimal set up, but not the A/C. It would require too many panels and too many batteries to use one. And even then an AC fridge would be a problem, propane fridge is more practical on a self contained system like that.
