VRM power flow Genset (ESS)

Hello, in my system I have a genset attachet to phase 1 via ET112. It is attached to the output of the MP2. In case the geset feeds into the system as it is in this screenshot, the power he feeds appears as AC load. In my understanding if I configure the ET112 to be Generator it should not increase AC Loads:

Do I need to rewire the ET112 or waht do I need to do to get the power flow in a correct manner?

dbus-spy shows the rigth values for the Genset:

Any hint?

The question is how to add a power source to the AC system for proper AC load visualization? In this case not a PV inverter.

Morning guys, I must insist, if I connect a inverter behind the ET112 the AC loads are calculated correctly. But defining a Generator on the same Meter the AC loads calculation is wrong. What’s my mistake what’s wrong? Must the in/out on the ET112 be rotated?
