Configuring Dual Phase Quattros with Gen, Batts, and AC coupling

Hi All,

I have an (Australian) 240V dual phase grid connection. The phases are 80A each and are separated at 180 degrees so 480V is measured from one to the other. This is my first time in the dual phase world.

I am currently thinking 2x 15kW Quattros, with Fronius AC coupling inverters and a genset. I have a range of questions including;

1) Will this system effectively manage an imbalanced phase load of say 120A on one leg?

2) Will 2x single phase Fronius AC coupling inverters load share between them or will each device’s maximum contribution be limited to half my total solar panels and each to one phase only?

3) How is it best to configure/connect the generator?

4) Is there a better way to go about this?

Thanks in advance for your thoughts
