Multiplus inverter "DC input low shutdown" value variable limits

I have a Multiplus 3k 12v 120v and I need to program the inverter setting low V cutoff (DC power low cutoff) lower but the programming interface seems to limit that value based on some other setting or parameter. Can anyone tell me what limits how low I can set the DC power low cutoff inverter value?

I want to set this to 12.25v but can't seem to get that low in VEconnect.

12,25V is a very unusual value.

What kind of Lithium batteries do you have?


With 4S LiFePO4 the nominal Voltage is 12,8 and cut-off around 11,4-11,8V

Charged it is around 14,2-14,4V.

Also, I read an article about this now. looks like shutdown related to restart with a 1v gap programmed. I need this lower as 1v on lithium is almost a complete charge cycle. The cutout at ~ 30% SOC can't be recovered from unless the batteries are almost completely recharged. This is currently, essentially an inverter that cannot use the benefits of lithium batteries. Can this be fixed by Victron?

I can't be the first to find this. Is there another thread on this issue? thanks
