Mac: Is this breaker perchance a GFDI breaker? If so, the tripping could be indication of current flow in the bonding leg. This is a more nuanced problem.
William Miller PS: I am not familiar with the Midnite charge controllers. I do know there are differences on how charge controller negative leads should be connected from manufacturer to manufacturer. For example, Outback charge controllers can accept just one negative lead from a common bus. Blue Sky controllers, on the other hand, require both a negative connection from the PV and one to the battery bus. This should be checked to eliminate as a contributing factor.
