3 phase asymmetrical system?

I noted from another forum answer by @Johannes Boonstra (Victron Energy Staff), that 3 phase asymmetrical systems are an option.

Different numbers of multi's on each phase.

I understand the need for AC and DC cabling symmetry within those confines.

However, when I look at the ESS assistant and the PV assistant the first message that flashes up is that there must be a symmetry of multi and PV inverters.

In an off-grid set-up, if I want an asymmetrical system as far as Multi's go, do I have to forgo the option of AC coupling?

Correct, ESS is not supported for unequal units per phase.

Thank you, I suppose that rules out AC coupling as well.
