That a/c is 10.5 amps at 120 volts. 1260 watts + 10% overhead and some power factor puts you right at the inverter max. Batteries are providing 120 amps and you need 4+ to get any reasonable run time.
BTW what size and length is the 12v wire? 5' of 2/0 would be about my minimum rating.
Ahh. I used the wrong voltage to get my watts. Duh!!! I have 8awg to my inverter plus start-up surge amperage plus not enough batteries seems to be the issue.
