Dometic Briskair 59516 Air Conditioner 15000BTU

Compressor rated load 12.3A. Com locked rotor 77A. Fan rated load 2A. Fan locked 5.6A. Minimum generater size 3.5/ 5KW
I am trying to find out what the smalest generater I can run this on if a Magnum MSH 3012 3000W 12V 125A inverter with load sharing is used for the startup inrush of 4 6V 260A Batteries.
Thanks. Frank

    Ok thanks everybody, the 3000 may be a better fit as it is quieter and has a longer run time.

    2000 is marginal (13.3 amp rated) and may work fine. Yamaha 2400 might be a better fit.
    Make sure the choice is compatible with an extended run fuel tank that I assume you need.
    The actual draw is probably a bit less than the max rating.

    You might run it with a 2.4kw set- something that is rated at 2kw continuous, but 2.4 continuous will certainly run it (though, as you know, not always start it).

    Do keep in mind derating for altitude.

    That was what I was wanting to find out not real good with electrical. If a overcast day not much solar but not so much demand for air either, I was thinking Honda 2000/1600 continues or the 3000, longer run time and maybe quieter as less load. or Yamaha 2400 But I do like Honda products.

    It's difficult for me to answer without knowing just how much sharing the inverter will do. This could get complicated.

    You may have a cloudy day with very little solar. A single 2kw generator would barely handle it by itself.

    No I was intending for generator to supply the power and only use inverter for startup sharing, but the inverter may be able to do some sharing as I have 600W solar producing op to 30A.

    Does the inverter share the load while the ac is running?
