3 Phase MultiPlus with different phase loads

Is it possible to mix MultiPlus II inverters in 3 phase system? For example one 5kva model and two other 3kva? Or have 4 inverters - two sitting on phase 1 and other two dealing with phase 2 and 3?

Anyone build such system?

All of the units within a system must be that same model. You cannot mix different size or model units in a multi phase or single phase system.

Here is the documentation:

Yes it works.

At the moment I have one inverter on L1, two on L2 and one on L3.

@Wojtek M

My Victron installer told me that only size of the inverter and its model must be the same in the 3 phase system. Number of units per phase does not have to be the same.

Soon I will test it in my system. I am waiting for a warm day to do it.
