okhmbldr post may be OK for him but there is no real context.
What's needed as others have indicated: A/C size - Is it really 12K btu, battery size and type, ambient temperature and insulation, amount of time the compressor ran vs just the fan, inverter model.
On another board a knowledgeable poster has a 5K btu A/C that he runs for 2 hours with 4x GCs or 460 Ah total.
A 12K A/C uses about 1200W or 10A AC. Thats 110A DC or 110Ah which is a significant battery draw, maybe more depending upon inverter efficiency.
