In short, I have 2- 390 w panel's, MPPT Renogy 40a controller 2/24v 50 v max, ,000 w max. My 4 batteries are Interstate 6v 234 ah each. My Pure Sine Wave Inverter is a 4,000w 24 vdc to 20 vac. My Solar panel Specs are ASP390, VMP 50.4, IMP 7.83, VOC 59.87 and fuse 5a. My AC window unit is a cheapie Walmart 20 vac, 5a at 5,000 btu. The data plate says LRA 20a. Obviously this will be a 24 vdc system and what I'd like to know is if I'm better off wiring solar panels in series or parallel. Lastly, should batteries be wired series parallel or just in series? I'm hoping to run AC unit 8 hour's a day. I ordered watt meter too. My panels will lay flat and i live in southern Florida. Everything is NEW.
