Need some help with the appropriate ground relay settings for (2)-Multiplus 12/3000/120 set 180deg-split phase.
Setup and programmed the system at a friend’s shop and followed the set-up Youtube video with the Master having “Ground Relay” ON and the Slave having it OFF. All worked great on both shore (2)-leg 50amp and on (2)-leg generator- with both units acting as one when it came to charging.
Currently plugged into an RV parks 50amp pedestal and the units will not recognize the incoming AC. A call to my friend revealed that his shop has the ground and neutral bonded.
It was suggested I turn the”UPS” to off, did so, but no change.
Any suggestions would be much appreciated.
