(On-grid) generator+grid management with AC-coupled PV

Dear All,


I've seen several topics on the matter, which I duly noted for when commissioning will come, but they did not really answer my question :


Let's say there is grid on AC-in 2 and generator on AC-in 1, and AC-out coupled Fronius inverter, feeding excess PV power to grid activated.

Does the CCGX automatically deactivate feedback to AC when the generator is ON (AC-in 1) ?


Or does it consider a single AC bus to feed back to, and then I will have to install my own reverse current protection device at the generator output? (Or install the PV on AC-out 2, opening relay when AC-in 1 is ON, as explained on other threads)


Thanks in advance!

Quentin
