Hi, I am wondering if it is ok to use a Midnite Solar 6 breaker combiner box with the positive bus bar split in two and use it to feed two Victron SmartSolar mppt charge controllers using the common negative busbar? Each controller would receive their own positive and negative cables, only the negative busbar would be shared.
The arrays would be different sizes feeding into a Victron 150/100 and a Victron 150/70 feeding into a single battery. Midnite Solar states most charge controllers can work in this configuration with a few named exceptions (Victron not being one of them). There is a diagram similar to this setup on page 5 of this document:
I just want to make sure before I make a potentially expensive mistake! Thanks in advance for any help.
