2 multiplus2 for phase compansation?

okay this is the problem :

in a nother question i asked why my quattro 8000 does not feed in any more after fw update. still wait for answer ;)

anyway this is a new one till i figured the first question out.
i have 3x 3000 multiplus 2 and 1 quattro 8000. first my idea was the 8000 for one house and the 3x3000 for a nother.

new idea the 8000 for "house1" grid l1 to ac 1 and then ac 1 out to house l1.

multiplus 1 ac in 1 to grid l2

multiplus 2 ac in 1 to grid l3

multiplus 3 ac in 1 to grid l1 "house2" so there is at least some phase compensation happening ;)

configure multiplus 1 & 2 to phase compansation for house 1

em24 is infront of all victron gear at grid.(both houses...)

can this work? the quattro does not need to be connected to the cerbo gx but can if it is possible?

there are no 3 phase motors or machines anywhere in the house1.

Thank you for ur answers.

@wudycool

Maybe a drawing of the idea will help.

Does the second system have its own batteries and gx? It would need to

yes secound system is different house 200m away with separte batterie and gx :)

i think tho main question is:
can you do phase compensation with 2 multis in a house with 3 phase grid.

Yes you can.

2 programmed at 120° in rotation to each other if you want one system supporting two phases.

Or as two individuals with no relationship to each other on separate phases. Since three phase is not a need for you.

Or as a parellel setup with 2 multis on one phase and a separate multi system on a other phase.

A drawing would still be useful to clarify things.
