Victron Multiplus 2x120

[caymaanedge]

Installed my Multiplus II a few months back. All good.
Started out on a big trip today and the inverter keeps shutting down due to Low Battery Voltage. Batteries are 13.3v, fully charged for my batteries, so no issue there. I reset, disconnected and checked everything to no avail. Any ideas? TIA

inverter keeps shutting down due to Low Battery Voltage.

You are referring to your MP as the inverter here?
Can you post a pic of your MP settings?
What is your battery bank?
What are you doing when the inverter shuts down? Big load(s)?

Yes Multiplus Inverter
I’ll have to get the setting tomorrow
680AH LifePO4 batteries - have been installed for 1-1/2yrs
Multiplus II was installed last fall
I tried to restart it. Shut down from app and rebooted, turned off physical switch. In short order I get a message of Low Voltage.

Batteries are 13.3v, fully charged for my batteries,

Do you measure this voltage at the battery and where the battery wires enter the MP? Or where are you getting this number?
13.3V is full enough, especially with 680Ah.

In short order I get a message of Low Voltage.

Is this in the app or ??

Measure voltage at the +- connection at the MP which was the same as measured at each battery.
The MP shuts off and when I restart it, app controlled, it tells me it has Liw Votage.

Okay that rules out everything from battery to wiring into the MP.
This was showing 13.30V?

Can you show the app view of the MP battery settings?

Well I connected laptop and went over all of the settings, re-saved then. It seems to be running fine now. Maybe there was just a software glitch.
Thanks for the help!
I will watch it the next couple days and let you know if there are any other issues.
