I plan to add (4) Renogy 320w 24v panels to my 5th wheel. Batteries are (3) 230ah 12V lithium. Panel specs:
Electrical Data:
Maximum Power at STC*: 320 W
Optimum Operating Voltage (Vmp ): 33.7 V
Optimum Operating Current (Imp ): 9.50 A
Open Circuit Voltage (Voc ): 40.1V
Short Circuit Current (Isc ): 10.08 A
2 of the panels will be on the front part of the roof, 1 in the middle, and 1 a little back from middle. I want to make sure to generate as much power when camping in partial shade as the sun passes over, so I was thinking either all panels in parallel if I can get away with it, or maybe the front 2 in series and the middle/back 2 in series.
Plugging this in to the Victron calculator, It recommended the 150/70 for either option. Anything I'm missing? Any big reason it's worth doing series-parallel over all parallel to make sure I'm getting some charge if a lot of the array is shaded as the sun passes over if I'm camping in trees? Thank you for your help
