hi there,
I have two 150/85 victron charge controllers that I want to use to charge a single battery bank.
I have two solar arrays, each is sized for one charge controller.
I know the pv positive cables from each array need to be kept separate for each charge controller. Can the pv negative from my two arrays be on a combined cable?
I would run a larger negative cable if the negative cables can be combined.
I plan to use a midnite solar mnpv12 combiner box, and combining the negative feed for both arrays is the configuration shown in the manual with two charge controllers. The positive feeds are kept separate of course. I would have to cut the negative bus bar in the combiner in half to separate it per charge controller.
If possible, please state why- if you recommend against
I haven’t been able to find much information on best practices to run multiple victron charge controllers with the same battery bank-
thanks
Chris
