I have a Victron Multipass III in my 2014 Unity MB. The feed from the battery is over 4/0 cable pair. Charger works fine. The inverter has worked reliably over the past 2 years. Today when trying to run the Inverter I am getting this Alarm condition, as soon as I run the Microwave Convection oven. The microwave draws about 1500 watts @ 120 vac so about ( 1500 / 12 ) = 125 Amps of 12 Vdc current. All AC wiring is 10 Awg. Trying to figure out what has changed, since it has been working up to now? Any ideas .. Google searches say it means battery is low ( I have battery 750 AHrs of Lithionics ) fully charged, or they say wiring is at fault? I checked Continuity of wiring from inverter back to battery buss, in tact and very little resistance due to 4/0 welding cable used?
