Victron Multiplus 2 - bridging the neutral conductor

Hello everybody,

I'm planning a PV system with storage for a buddy and I've run into a problem ...

Specification:
-Two-family house, two counters
-Common batteries
-Two Multiplus 2 500/70, one for each apartment
-Fronius SYMO 5kVA
-CEEE socket in the garage
-ESS, zero feed

So there is no problem with the independent power distribution to the apartments, but there is a problem with the CEEE socket. Here I would have to bridge N conductors from multiplus input and output.

Is it allowed?

I don't understand why the input and output are separated from N (?)

To understand my problem, I am adding the scheme I have planned so far. There is a mistake. Apartment 2 gets L2 instead of L1 from Fronius. And CEEE doesn't get an L2 from Fronius.



Greetings,
Bartek.

You should not do this.
When the backfeed relay inside the MultiPlus is open, then its Neutral contact will be bypassed and then with the Neutral - Earth relay closed, there will be two MEN connections, which is not allowed in any district that I know of.
