Almost every day my Mutiplus II in my motor home disconnects from my AC busses. My vehicle is plugged in 50 Shore power from a house. When connected it shows 50 amps and all the busses are powered. Almost every day, late morning and until late afternoon, it disconnects from all the busses and shows only a 30 amp input and reverts to only battery charging. Needless to say, I have no AC when it's disconnected.
I wonder if the line voltage coming in drops below the Muliplus II limits. If so, can I, and how do I lower the limits?
