Hey Josh, Good ideas as always. I'd really prefer to run AC off the batteries while on the hook. It doesn't run continuous all night, but cycles and most nights, I turn off the AC for the night after it's cooled down the cabin. Usually around 11pm. I would invest in Lithium to a point.

The simple math shows that if you need 12.5 A at 120 V, you will need 125 A at 12 V. This is assuming 100% efficiency of the inverter. I bet that they are around 80%, so add 20% to that number (1.2 x 125 A = 150 A). Run this for 12 h and you will use 150 A x 12 h = 1800 Ah. In order to

If it helps, think of the inverter as a special kind of extension cord. It passes power from Point A to Point B. It does not create or store power. It needs to be bigger than the expected load put on it. The batteries need to be up to the task, but they do not create any power, they store it.
