The code only requires the RSID (rapid shutdown initiation device) to be on the exterior of the building. Would it work to put the RSID on the garage exterior? You could route your PV circuits to a switch or switches on the exterior of the garage on the way down to the sub it ties into. You could also use a shunt trip breaker(s) for the PV circuit(s). If for some reason you need to have the RSID on the main house, it gets trickier. Might need to trench?<div><br></div><div>August</div><div>Luminalt<br><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Nov 23, 2021 at 7:24 AM Christopher Warfel <<a href="mailto:cwarfel@entech-engineering.com">cwarfel@entech-engineering.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<p>I would appreciate ideas on how to shut down a proposed
microinverter system on a garage that is 100% serviced by an
Outback Radian multimode system in the main building that has the
garage on the back up service panel in the main building.<br>
</p>
<p>Garage has a MLO subpanel that is connected to the multimode back
up service panel that is in the main building.</p>
<p>If grid goes down, we need to disconnect the microinverter array
so it does not overcharge the battery system. If we use the
battery voltage relay, we will take out all the garage circuits,
which would disable its heating system, etc. We just want to
disconnect the microinverter circuit in the garage subpanel.</p>
<p>Does anyone know of a product that could do this. I would imagine
a transmitter, or perhaps something else besides a microinverter
array? <br>
</p>

<p>Thanks for any help. Chris<br>
