charge current limit of the battery is ignored

Hi,

i have a 48V system with Cerbo,Multiplus, MPPT (450/100) and battery.

At the moment the battery is full and the battery sets a charge limit of 0A. I can see it in the cerbo menu (CCL = 0.0A).

But the MPPT is charging the battery with full current. Only if battery sends an error message, the charging will be stopped for a few minutes. After 3-5minutes charging starts again until next error message.

I tried to reduce the current with activating DVCC and set a current limit of 0A. But this will also be ignored.

Are there any other settings which could affect this behavior?
Thanks in advance

DVCC has to be active otherwise the battery cannot manage the chargers.

Has the battery been configured as the reference in the GX system setup?

How is the mppt connected to the Cerbo, is it marked as external control?
