ESS with Multiplus and Fronius

I currently have a working installation with SolarEdge and Fronius. I have acquired a Victron Multiplus II GX to include a 280Ah lithium battery. The idea is to integrate the Fronius (3 kW) with the Victron system. Additionally, I will install an MPPT 250/100 (6,600 W peak in panels) to charge the battery and take advantage of the surplus energy once the battery is fully charged.

The Fronius will operate in AC coupling. My question is: if the battery is fully charged, will the Multiplus II (5000 VA) be able to feed all the energy provided in DC by the MPPT into the grid, or will it be able to reduce its output to avoid damaging the system? It could happen that, at a given moment, the Fronius provides 3 kW on the AC OUT side, and simultaneously, the MPPT delivers around 100A at 48V from the DC side. Therefore, in theory, the Multiplus would be feeding about 7 kW through the AC IN into the grid. Is my reasoning correct, and would this setup avoid damaging the system?
Thank you!!
Here the schema:

Yes it is possible but you must properly configure the ESS in your gx
