Reviewing the posts, I agree that wouldn't help.

Then you have to find a 600V DC rated contactor.
If you are going to use a contactor, which the
original poster said he couldn't do, why not use
the 240V AC rated, costs about $129 for a 30A contactor.

Why not disconnect the DC into the inverter with a Tyco relay? No DC, no AC.

Hi All,
I am looking for options for controlling a disconnecting relay for a
grid-tied inverter. It is a PVI5000 so 30 amp 240vAC. I need to
disconnect it when the backup generator gets kicked on by the Automatic
Transfer Switch when the grid goes down. The array is on a garage that is
several hundred feet from the house and service entrance and ATS and
digging in a control wire for that distance won't work. So I need a way
to sense that the generator is putting out power and then control a
contactor which would disconnect the inverter from the subpanel. I've
looked for wireless and powerline control options but I can't seem to put
together the pieces.
Any ideas of the most cost effective and reliable approach?
Thanks,
Howie
