Cerbo Gx does not recognize Fronius Gen24 inverter

I have a simple ESS with a Fronius Gen24 PV Inverter on P1 and the MP2 also connected AC in to P1.

After activation of modbus UP access in the Fronius console, the cerbo displays a Fronius inverter but shows "unknown inverter" and also shows it only connected with one Phase. Because of that the values on AC Loads are always wrong, if you add the charging power plus the AC loads you get more than the PV is currently delivering.

How can I make the cerbo detect the correct Fronius type?

Cheers Thomas
