My SoC is jumping to 100% every day at around 2:44am.
This behaviour is new and I did not change any settings the last few weeks. I think this could be firmware-update related, due to some similar threads I found here.
The BMS is just for Cell protection. I use the SmartShunt 500 to measure the SoC.
The drop-off of the SoC after the 100% is me manually adjusting the SoC via Victron Connect on the SmartShunt.
This figure shows, that the voltage is acting normally.
