Since the PV system is connected to the breaker panel, it will see power from the generator when the generator comes on. How does the PV system know the difference between POCO and genny power from it's connection at the bottom of the panel?
I think an anti-islanding device is the best, safest and easiest way to go.
SMA used to make a cool anti-islanding device called the Sunny Island where you could connect multiple power sources to it along with the grid and it would provide safe and proper connections. I just went to their site and now Sunny Island is the name for their inverters, which seem to incorporate the features of the previous Sunny Island devices.
The way I understand it, the OP has changed the design so the invertor is on the normal (POCO) side of the ATS so it won't "see" the generator output.
