Seeing what it takes, both in weight and expense, I'm not interested in solar enough for the A/C. I just figured there would be enough battery power to run it a couple of times a day.
What I am interested in is being able to keep my batteries charged by solar (eventually). I'll assume the two batteries (the picture confused me and I thought there were two banks of 2 batteries) are the lower tier (Group 24) and has a max capacity of about 170 AH. From what I understand is I'd be in good shape with about 400 watts of solar as long as it was mostly sunny.
Anything more (the A/C) and it's time for a hookup or the generator.
