<p class="MsoNormal"><span style="COLOR: #1f497d"></span> </p>
<p class="MsoNormal"><span style="COLOR: #1f497d">Honestly, there is a very small probability that any PV will ever make it to the grid. The service is 1000 Amps and the building has multiple servers running continuously, all day every day. I am hoping to forego
the dumpload option and the added costs. Word is, they will begin discussions in the coming months addressing this issue. In the case that they decide to allow it, it would be an easy fix to remove the contactor and splice the conductors.
</span></p>
<p class="MsoNormal"><span style="COLOR: #1f497d"></span> </p>
<p class="MsoNormal"><span style="COLOR: #1f497d">I have heard rumors that a contactor like I described does in fact exist. But that was some years ago and I cannot remember the details.</span></p>

<p class="MsoNormal" style="MARGIN-LEFT: 0.5in"><span>Greetings Esteemed Wrenches,</span></p>
<p class="MsoNormal" style="MARGIN-LEFT: 0.5in"><span></span> </p>
<p class="MsoNormal" style="MARGIN-LEFT: 0.5in"><span>My company was recently tasked to engineer a PV project in Alabama. We sat down for a meeting with all of the local big-shots. They proceeded to let us know that we are not allowed to feed any excess PV
power onto their grid, production cannot exceed demand. I am hoping that y’all might be able to steer me towards a contactor assembly or device that would detect reverse current flow, trigger the contactor, then open up the inverter AC output circuit. The
service is 3-phase, 208 volt. The maximum current we intend to introduce is 70 amps, continuous.</span></p>

<p class="MsoNormal" style="MARGIN-LEFT: 0.5in"><span>Appreciate your advice,</span></p>
