Multiplus II GX 5000 SOC jumping to 100% with no reason , batteries nowhere near full

As per title , this happens at least once a week from what I can tell.



This morning , it has just jumped from 73% to 100% , solar PV only just started kicking in , system voltage is way below still at 53.80 volts , absorbtion is set for 55.70 on MPPT controllers and in Multiplus is set to assume 95% SOC at 55.70 volts.


Any ideas?


I have just downloaded the data in excel where it confirms this as well.


Please see attached screenshots

You forgot to include a screenshot of the inverters general tab, regarding SOC settings.

Are you using "2 signal BMS" assistant or ESS with this settings set in it?

@mvader or other Victron Gurus , would you mind looking at this to see what might be causing the issue?

Why are you complaining? You clearly don't care about actual battery SoC since you're using one that can't count the incoming current from the PV.

Contact your reseller for support.
