So your 200 watt panel put out a peak of 118 watts and a total of 850 watt hours, not 850 watts. That would run a very small, 300 watt, A/C for almost 3 hours. It would run a more typical small unit for about 1 hour and a medium size RV A/C for about 45 minutes. To make up for inefficiencies, a bit of cloudiness or shade and the use of panels mounted flat on the roof and some other minimal electrical use, I would think maybe a 1000 watts of panels would be about right. You would also need a minimum of 1000 AH of batteries which is about a dozen car sized batteries.
Hi Jim
That was just one day with a rigid panel not installed laying on a garbage can or the ladder rack..There will be shortly 400 watts of solar installed and 200 watts portable..I am confident it will run that AC unit and doubt I would need the portable panels..
Early in the day but I just checked my Bluetti charging with two 100 watt panel flat on the roof putting out 106 watts,then checked the 200 watt panel charging my two LFP batteries at 121 watts..Thats 227 watts coming in for a AC,early in the day meaning it's right on the 70% cycle of the 330 watts,and the solar will get better...
I have 400 watts of lifepo4 batteries all together plus the 55 or whatever of the bluetti LFP and 600 watts of solar now..I do not see a problem..
Infact maybe tomorrow I will run the AC off of the Bluetti 70(700 wh) with 200 watts of input(max) more like 180-190 and see how long it last..
Just for kicks and giggles..LOL
