Fronius inverters connected to AC out1 not showing on VRM

In a Victron system with three pieces of Multiplus 48V/5K, I connected three pieces of Fronius Symo inverters (total 13K) to AC out1 and two pieces of Fronius Symo in parallel with the Victrons.

The total energy of all five inverters are showed in the remote console as if all five fronius inverters were connected in parallel with the victrons.

Another strange thing is that the AC loads shown are in fact the AC production of the three Fronius inverters connected to the AC-out.

What I would expect is the following:

- what is shown as AC loads should be 0W; instead of that the Fronius inverter production on the AC out1 should show up as 1533W as PV inverter on ACout1

- what is shown now as PV inverter (2961W) should be 2961-1533 = 1428W for the two Fronius inverters connected in parallel with victron's.

What did I do wrong?

You have to configure where the Fronius inverters are connected (Detail of the Device at cerbo). Seems like all are configured for ac-in. The calculations are certainly wrong then.

Hello

Please could you tell us when is Victron going to fix this problem with the Fronius Gen24 Primo registering as a Tauro Multiphase in the GX and can not be changed to Single phase running on L1?

Thanks
