One Multiplus II-GX 48/5000/70-50 with Fronius 4.0 on a 3-phase grid connected system.

Hello, I plan to use a Multiplus II-GX 48/5000/70-50 with Fronius 4.0 on a 3-phase grid connected system. The 2 phases are connected directly to the consumer and the phase-3 will pass-through the Victron-Fronius system supporting Energy Storage System on one phase only . I have the next 3 questions:

1, Does the above system works fine?

2. Is the Multiplus II-GX anti-islanding certified and does exist a certificate for Greece?

3. Assuming the 3 grid phases are on. Does exist the possibility on the above system to have on the 2-direct phases 50Hz grid freq. and on the phase-3 higher ( for example 52 Hz) due to MG shifting on frequency? (This frequency unbalance would be abnormal for 3-phase loads).


Best regards,

Pavlos.
