I have a MultiPlus 12/2000/80 managing my power system on a 2012 Sprinter Van Conversion. Inputs include solar, vehicle alternator, 2,500-watt Cummins Onan MicroQuiet generataor and shore power (generator and power connected to transfer switch). The system worked well for two years. This past week I turned on the generator and ran a vacuum cleaner. Not sure if I tripped anything but the AC in hasn't worked since. I happened to have my Victron Connect on while using the microwave (with generator running) and realized I was drawing down the house batteries (2X 100 ah battleborns). Checked and played with my settings on VE Config and can't get the AC work through the MultiPlus. I can see voltage coming in and frequency (~61 hz). Wiring wasn't really handled at all and appears to still be solid. Is there something I can re-set? Any help would be appreciated.
