I have 950 watts of panels on the roof of my RV and 5.3 kWh of lead acid batteries. I feel like my family of 4 could live forever out of it. There would be no AC or other high wattage appliances, except a blow dryer and a microwave for about two minutes, three times a day, everything I could, including the fridge would be gas.
I’ve decided that in AZ weather in the summer, AC is not doable for me without at least tripling my panels and batteries.
I could probably run my AC off my my inverter, but I max out at 74 amps production when I add 400 more watts of ground panels, but my AC would use at least twice that to stay on.
Ive also found that I can only produce that 74 amps for 4 hours a day. So the tripling my size of my panels would have some angled East, South, and West to maximize sun production at different times of day
It’s only in the 90s today, and the RV AC runs nonstop set ro
