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

<blockquote type=cite class=cite cite="">Then you have to find a 600V DC

$129 for a 30A contactor. <br><br>

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

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