Solar Air Conditioner

We lived in New Mexico as kids and adults and swamp coolers worked great except for the months of July and August when we had our "monsoon" and we got 3/4 of our precipitation, maybe 6" and the humidity negated their capability. A normal RV a/c is 13,000 to 15,000 Btu and would require 2 kW of solar panels to operate. We have 1400 W and about 9.6 kW-hrs of LFP and have operated 3.5 hours as combination, dropping 1200 kW-hrs per hour. We could go for six hours and still be above 80% Dod but do not like going below 60%. The last several days have gotten back to rig in late afternoon with sun at low angle or in shade. Internal temp was in low to mid 90s and just ran a/c on battery suite for half an hour or so and got temp down to low 80s. We have two to four 12V outlets in each room aka cigarette lighters

After that, we use a couple if 12 V fans that make things comfortable.
