2 Multiplus 2 and 1 Quattro 2 for 3 Phase System?

Hello,

I plan to expand my system to three phases. I currently have one Multiplus 2. Since I would like to add our existing 1 phase generator, I was thinking about adding a Quattro 2 and another Multiplus to build a 3 Phase system.

Can I build a 3 Phase System with 2x Multiplus 2 (on L2 and L3) and 1 Quattro 2 (on L1)?

When in normal operation all systems would be connected to the grid. In Case of an power outage when our (DC coupled) PV wouldn't supply enough energy, the generator on the Quattro 2 would charge the batteries and supply L1 while the two Multipluses supply L2&3 via the battery.

Allright, thank you. So I would need 3 Multiplus 2 and an Battery charger for the generator to make it work or feed in after the inverter and set one Multi up to have an AC Source on the AC Out... Just like an DC Coupled Solar Inverter.
