3 x Quattro's in 3 phase with single phase shore connection

I've got 3 x 10 kVA Quattros set up for a 3 phase AC load.

The primary generating source is a 48 V DC Hybrid Generator and lithium battery system connected to the Quattros at 48V DC.

There is a intermittent AC mains resource that I'd like to utilise to charge to batteries or feed the load when available, the AC connection is in single phase. At the moment, the AC-in connection is wired up at 3 phase with 1 phase connected to each of the Quattro AC-in-1 connections.

Can I connect a single phase AC-in even though AC out in 3 phase ?

Should it just be connected to 1 phase only ? i.e. 1 quattro AC-in connection or should I parallel the AC-in across 3 Quattros ?

Hi @EnergyLad

Yes it can be done...but (there is always something...) it cannot be used together with ESS / grid code (but giving the irregular grid that probably wasn't the plan already)

You have to connect a single phase to one of the inverters indeed, not all of them.
in ve.bus system configurator you have to de-select 'switch as group' for that input.

Love the flexibility you can achieve with these systems.
