Multiplus II shutting down at 11.4 volts

Discovered a new issue. My low level setting for inverter is set for 10.5 volts, but is shutting down at 11.4? My victron shunt is reading 11.4 volt @ 75% battery and shuts down. Help!

11.4v is definitely not 75% SOC.

What you might find is underload the battery voltage is lower.

Are you using ESS at all?

This is happen during dry camping and a compressor was plugged into RV at about 2:00am. The inverter would not turn back on even when victron battery shunt displayed 11.4 volts.


As far as ESS, I have 700 watt solar on top of RV used with victron MTTP charge controller. Battery bank is (4) 100ah 12 volt lithium batteries.


Also, after I turned ff the compressor, my shunt was reading 11.4 volts-that would be with virtually no load.
