Hey!
Currently I have 2x100watt panels wired in parallel and connected to a 20amp renogy mppt on my RV. I am looking to do a total overhaul by adding 3 more 100 watt solar panels, so total of 5 x 100 watt panels.
From my understanding, I will be needing a 60amp MPPT controller and I'm planning on getting a renogy one which seems to only be able to take max 48 volts. 5 panels in series would bring it to a 60 volt system, which I guess would eliminate the plan of wiring all in series. Plus, I'm planning to cluster 3 solar panels together and a few feet later cluster the last 2 panels. See my diagram in the image attached. I feel like I want to kind of have 2 "independent" clusters since they're a few feet apart so that if one cluster is shaded, the other one is not affected. Is it possible to do what I'm showing on the diagram with a single charge controller, or am I displaying a total lack of knowledge
? or should I simply connect them all in parallel?
I also want to keep the output at 12v as I'll be hooking up 3x100ah batteries in parallel. From my understanding, the charge controller can convert 48 volt input to a 12v output going into the batteries.
