I had a Multiplus II 12/3000/120 and Smart Dongle installed in my motorhome in february by a certified Victron installer. The components have served me well since then but just now experienced a complete loss of power from the inverter. There is 13 volts present at the input side; VictronConnect shows "Initializing" and the unit is not powered on. I am connected to shore power and also have run the generator, the battery bank (3x Li Time 230amp) is currently at 91% but the Multiplus unit will not power on (there are no lights).
Based on other Victorian users with similar problem, I have tried cycling the power button from inverter/off/charger several times. I have tried cycling all power (battery, shore, generator) to no avail. I have disconnected the Smart dongle and still no success.
Is there something else I can try? I do have a message to the original installer but I am dead in the water until after the holiday.
