Orion XS - Shunt Diagram

Hi,

I recently replaced (2) Orion Dc-Dc 30a 12v Isolated chargers with (2) Orion Xs 50a chargers and am very happy with the output.

However, I have a Simarine 300a shunt between my combined generators (3 solar mppts, 2 orions) and my bus bar.

Since the Orion XS is non-isolated (shares a ground) how do I shunt the output on the negative side?

Thanks,

I am not familiar with the Simarine shunt, but if this were a Victron shunt then the system should work like in the diagram below. I only have my tablet with finger drawing at the moment but it should suffice. The batteries obviously now have a common negative and this could be direct or via ground point, both cases are shown and the shunt goes in the common cable. The balance ground cable goes to the source battery side. The negative charging current flows between the 2 batteries via the shunt.
