I wired in an AT today on the outputs of a dual multiplus split phase RV system. Everything is working fine but I don’t believe I have my ground relay situation the way it should be. When I’m on shore power or inverter I do not get a 12V output from the MP relay terminal, the yellow relay light on the AT does not come on. I did un-check the ground relay checkboxes on both MPs in VEConfig.
What I may have incorrect is I have the ground wire from the bonded MP ground outputs going into the green/yellow input on the AT. Also, I was not sure where to place the ground wire on the AT output, I have it bonded to the green ground wire on the chassis on the screw terminal. Should either of these ground wires be rerouted or removed? Could that be the issue? Can you think what else could be the problem, if I do have a problem? Everything appears to be working correctly but I may have a safety issue that I’m not aware of.
