I have 4 x 100watt Rich Solar panels on my van roof (22.6 open circuit voltage, 5.4 amps) that will be used to charge a Bluetti AC200.
They are not wired yet because I'm trying to figure out whether to use parallel or series setup. Parallel will provide more consistent charges when the panels are in shade, but all of the sites say use series. Since the van is used on camp trips shade is going to be an issue.
The big question is, what's more important to charge the AC200? Amps or Volts?
PARALLEL: 4 panels x 5.4a = 21.6 amps
vs
SERIES: 4 panels x 22.6v = 90.4 volts
