Hi, I have a Victron Multiplus 12/3000/120-16 on my boat. When running the inverter with no shorepower and engine off, naturally the domestic batteries slowly deplete. Eventually, the low battery warning light on the Victron starts to flash. I assume this is triggered when the battery bank voltage drops below a certain value. What I am not able to find in any of the documentation I have is what that voltage threshold is, and whether that broadly corresponds to (say) 50% discharge of the battery bank, or some other value (obviously I don't have a battery monitor fitted). Can anyone help with that data?
Ultimately what I am trying to decide is how severe a condition that light indicates - does it tell me I am damaging the batteries with a deep discharge, or is it just saying "time to top up skip"?
The domestic battery bank is 5x110Ah, about 3 yrs old, and the firmware version on the Victron I think is 150 if that is relevant.
Thanks in advance
S
