My intention is as follows
To install 8. 425watt solar panels onto the roof of my bus.
The voltage of each panel is 41.3v
And the amperage of each panel is 10.31amp
41.3v x10.31amps= 425w
I want to wire the panels in parallel to remedy shading issues (partial shading of one or two panels affecting the whole array)
But when wiring in parallel amperage increases whereas voltage stays the same
So in this case my amperage would be 82.48 amps
Which would require 3 gauge wire rated at 100amps.
My thoughts are to have two separate arrays with four panels on each array…. This would max out at about 44amps or so, which would allow me to use six gauge wire for each array.
I’m wondering the cleanest/ most efficient way to accomplish this?
I would like to fuse the positive of each panel since my amperage is higher than the 10 gauge wire that the panels come with… but I don’t necessarily like the idea of having inline mc4 fuses on the roof of the bus…
Is there some kind of combiner box that is designed for this application?
If I decided to land both arrays on the same charge controller
What would be the cleanest way to parallel those two strings together? (Although I do doubt that Victron actually makes a charge controller than could handle both strings, so I’ll likely need two charge controllers anyway.
Ok thanks y’all
