Battery control with victron - home battery SoC bounces between 94 and 97% #11286

Describe the bug

Thank you for the great christmas release with two long awaited features for me - battery control and smart #1 support.

I use battery control with victron multiplus II inverters and Pylontech CANbus battery connected to Cerbo GX. Battery control works - kindof. Solar production is complety used to continue chargeing the home battery while pluging in the car and grid power is used to charge the car, as long as the home battery SoC is below 95%. If the home battery SoC reaches 96-97% the battery is still shown as locked in the GUI but is being discharged again until it reaches 94%, where solar charging of the battery starts again. So the battery bounces frequently between 94% and around 96-97% SoC every few minutes, which is not good. I am not aware of having configured 95% threshold somewhere. Where does this behaviour come from and (how) can it be fixed?

Charge current is limited to 9A / 6 kW in the vehicle definition to match the inverters 7.2 kVA capacity and have some spare for the building.

And btw: Battery locked state shows as "Battery (gesperrt)" in German localisation instead of "Batterie (gesperrt)".

Steps to reproduce

I am not aware of having configured 95% threshold somewhere

Das ist Teil des Victron Templates wenn Du battery control verwendest. Zur Fluktuation kann ich nichts sagen. Vielleicht @philipptrenz ?

And btw: Battery locked state shows as "Battery (gesperrt)" in German localisation instead of "Batterie (gesperrt)".

Danke, behoben.
