Looking for a flush mount wall plate for the round Victron MPPT Control. I have a GoPower PWM controller/Display mounted in the wall of my travel trailer. I am replacing it with a Victron 150/35 Blue Solar + MPPT Control. The Victron charge controller will be mounted below in a base cabinet and I’ll run the MPPT Control cable up to the area where the GoPower unit is currently. Ideally, I would find a flush wall plate that is large enough to cover the rectangular wall cut-out exposed when the GoPower unit is removed (the new wall plate would need to be 7 1/2" x 4 1/4"). I’m looking for a plate in either bronze or black and has the Victron MPPT Control mounting hole in it. It looks like all that Victron offers is a mounting box which I don’t want to use. Anyone have a solution?
