Syncing Multiplus and Shunt SOC

My Victron shunt and Multiplus are showing 2 different SOC readings. The shunt is showing 100% but the 24/3000/70 is showing anywhere from 70-80% SOC. I have programmed the shunt to know that the battery bank has 412aH @ 24v nominal.


How do I know which reading is accurate, or if either of them even are correct at all?

@Love2Learn,

is there any specific reason why you have the MultiPlus battery monitor activated when you also have a BMV/SmartShunt? There should only be one battery monitor in the system.

The shunt is the the one to trust while the MultiPlus internal battery monitor relies on calculated data.

I thought I had the battery monitor turned off. I'll go in and double check.


That being said, how do I make the SOC reading accurate with the shunt? I'll be charging from solar at 20 amps while the SoC reads 100%

Please post screenshots of your shunt settings and also battery settings from your MPPT.
