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!

Multiplus II shutting down at 11.4 volts
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.
Good chance the BMS shut the battery down.
ESS isn't intended for mobile use.
Under load a battery voltage drops.
What is the restart value programmed onto the inverter?
You will still need to address the SOC issue. Do you have a shunt?
Inverter is set to turn off at 10.5vdc.
Yes, I have a shunt installed
I feel I have answered these questions in my original post. If not, please elaborate.
I read the system turned off at 10.5v I was asking what it is programmed to do. Expecially the restart value.
And that at 11.5v the battery cannot possibly be at 75% SOC.
What batteries do you have lithium or lead acid?
