Multiplus AC Ignore, can a BMV712 send SOC?

I have a Multiplus 24/3000/120 that I want to prioritize solar charging from a SS-250/100. Grid power is available, and is to be used as a backup for solar issues.

I am using BattleBorn 12V LiFeP04 batteries in a 2S2P configuration.

I have found the voltage setting option for AC Ignore to be unusable with LiFeP04 batteries because voltage doesn’t fall as precipitously with SOC as it does for lead-acid or AGM chemistries. For example, at <30% SOC, voltage is still at or slightly above 26VDC.

I have a BMV712 monitor on the system, and wondered if it can be paired with the Multiplus to provide SOC data. Any info, along with required cabling, would be most useful.

Otherwise, it appears my only option is a rather expensive addition of a Color Control GX or Venus GX.

Thanks in advance!

After consulting with my vendor, BattleBorn Batteries, I am working on another setting, still in the virtual switch section, but voltage based only. If it works as desired, I will update here.

have a look at setting up assistants being hub4 or ess assistants as these can help out with power exporting options and also include SOC battery settings, Presuming you have a victron Venus device in the system that is
