I bought this to attach my Renology panels to my trailer's zamp port. I knew zamp had messed up the wiring for its proprietary connection. The charge controller showed reversal as expected so I used a blade swap to swap it out and all was fine. Not sure why, but the + and - panels didn't match the wire colors as expected, but I measured everything and it worked since it's just wiring.
