[RE-wrenches] Remote relay options

[Howie Michaelson]

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
