Nope,
With a 566 amp-hour AGM battery bank my 13500 watt air conditioner draws more like 200 amps. Wattage varies between 1200 and 1900.
If the OP is serious about running the roof air LI batteries and 48 volts is the way to go.
I, too, can run my roof air for a while from the inverter and battery bank--but 2old has 64 cells vs 24 cells for my bank. It does make a large difference to the load per cell. Lower rate per cell is always better for extracting the full potential (down to 50% of course).

Reality check: A 15K btu A/C draws about 15A AC and about 165A DC with an inverter. With enough solar and batteries you might be able to run a 5K btu system.
But otherwise you crank the gen for the A/C.
