I have a Multiplus II hooked up to use only as an inverter, overkill I know. However, I would like clarification. I have been having problems with my batteries charging. I don’t have the Multiplus II set up to charge the batteries. I have a WFCO converter set up to be powered directly through a switch off the breaker box on the side that will run off 30 amps directly. I am plugged into a 50 amp pedestal. If I have my Multiplus II turned on I have power throughout the coach, everything including ACs which are on the 50 amp leg side only. If I turn off the Multiplus II I only get power to the 50 amp leg side only, I can run the ACs, but I get to power to the 30 amp leg. For example Multiplus II on, microwave runs, Multiplus II off, microwave will not run. Isn’t the Multiplus II supposed to pass the current through without being powered on when set up only as an inverter? Is my transfer switch in the Multiplus II not working? Thanks all, sorry for the poor wording.

If the Multi is switched off, the ‘pass-through function’ will of course not work. The relays are then simply open …
You will then need a bypass switch for this function
