Hello! I’ve noticed my inverter stops at an unexplained voltage with the message:
“VE.Bus System - MultiPlus [275] - Low battery: Alarm.”
This is similar to the message in this topic.
My system consists of a Victron MultiPlus-II 48/5000/70-50 GX and two parallel-connected LifePo4 10kWh battery packs with a PACE P16S200a BMS.
Here are the settings in VE Configure:
I also don’t see any alarms coming from the BMS (via dbus-spy), but I do see the ‘Info/MaxDischargeCurrent’ set to 0:
When I look at the MultiPlus dbus data, I see that ‘Alarms/L1/LowBattery’ is set to 2, which I suspect is blocking discharge:
If I set ‘Controlling BMS’ to ‘None’ in the DVCC menu, I can discharge until the BMS intervenes.
Now for the question: Is the MaxDischargeCurrent value of 0 the cause or the consequence of the MultiPlus alarm? Do you see any other peculiarities?
Would it also be perfectly fine to bypass this by having the MultiPlus manage the charging instead of the BMS (which intervenes on its own if necessary anyway)?
Thanks!
