I was looking at the Midnight Solar MNPV6, and noticed a comment in an application sheet that it has a common bus bar for PV return current (-), but the positive bus can be split for 2 array circuits (which I need).
A footnote states: "Most charge controllers can have PV minuses common (Exception XW
and BlueSky)"
If I plan for two XW's, does this mean I need to look for another combiner? Suggestions? I need six 15A breakers.
It sounds like the safety ground must have its own buss bar or connection in the combiner, yet is not connected to the PV return(s), which isn't surprising but something I hadn't considered.
