Multiplus does not provide reliable voltage during pass thru of shore power. I can't run water heater without voltage in the trailer dropping from 119v to 112, try to run the air conditioner and its worse. If it is trying to charge at the same time, voltage drops more and if you try to power anything on AC it faults out, thats while on shore power. It gets worse the lower the batteries are, like the charger has priority over the ac loads. I have checked every connection, AC and DC and have no idea what it could be. The system was programmed by the supplier, so I am unaware of the settings. They tell me that the problem is on my end. Checked and double checked the wiring. What am I missing? It seems to run fine in inverter mode.
30 amp service, 8/3 wiring from the trailer plug to a 30 amp breaker, then on to the Victron ac in.
8/3 wiring from the Victron ac out straight to the 30 amp main on my trailer distribution panel.
3 Battleborn batteries, Solar w/ victron charger
