    More than you want to try and power with solar.

    2.1 Kw Suntech 175 mono, Classic 200, Trace SW 4024 ( 15 years old  but brand new out of sealed factory box Jan. 2015), Bogart Tri-metric,  460 Ah. 24 volt LiFePo4 battery bank. Plenty of Baja Sea of Cortez sunshine.

    Can you get an inverter based a/c unit?

    They have almost no surge, and usual run at a much lower continuous current when operating vs the high/off cycling current of a standard compressor.

    Overall, it is still a lot of energy from an RV based solar system.

    Im thinking of generator sizing not looking to run  on solar. I have a 10000 btu window unit that runs on a open frame 2000 gen. But I would like to no if a 3500 surge 2500 running would work for the rv ac?

    I run my travel trailer, including  air conditioner,  on a Honda EU3000i with no problem. 

    I hear good reports from Champion 2800 owners running their RV air conditioning.

    Champion inverter dual fuel here (https://www.championpowerequipment.com/product/100263-3400-watt-dual-fuel-inverter/) and it runs my 15000BTU rooftop just fine.  If I need to charge the batteries with my PD4060 the first bit of bulk charging will pull a good 1000w of power (AC not DC) from the genset, but I have enough headroom from the generator for both simultaneous if needed.  IIRC I have seen 1800w being pulled by the A/C by itself when it was working hard.
