There is a also a thread in the German section of this community discussing the problem:

I moved all strings over to the RS 6000 to avoid losing money from the RS 450 not feeding in.
@mpvader Is intentional that DC feedin Is not possible?
Any update on this? Still having the same issue. RS450/200 does not feed back to grid when battery is full.
My system is feeding in to the grid again since a few months.
I am not sure what made the change. I entered the grid code again in the Multi RS’S in the Connect app. And I installed firmware updates in the Multi RS’S and in the Cerbo.
I don’t have any solar connected to my Multi RS-es, but I have a separate Smart Solar RS450/200 that won’t supply excess PV to grid when my battery is full.
When my battery is not full and when DESS decides to sell excess PV to the grid, it’s working fine.
Did you install updates on all devices?
And, did you enter the gridcode in the Multi RS’S?
All devices are running the latest firmware, cerbo is on 3.70~26.
Grid code is set, otherwise I wouldn’t be able to feed into the grid at all.
