when the batteries are fully charged in grid isolated mode. All
the ways I can think of that would normally work to deenergize
the microinverters automatically based upon battery voltage
won't work. I can submit a drawing if that would help. I am
trying not to run another conductor circuit from the house to
the garage. I realize that would solve the problem, but it is
an expensive solution. English is my foreign native language. <br>

<div dir="ltr">Hi Chris - If I'm following you right, you have a
PV system on a detached garage that ties into a backup subpanel
also in the garage? 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?

<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>
