<p>Yesterday, I was able to upload firmware to the Mate 3s, and the
GS4048 and program it for AC coupling. I did not realize a
firmware update would shut down the inverter (makes sense that it
does), so that was a bit of a surprise, but all in all it went
very well. The Mate3s firmware was out of date by almost a year,
and that did not allow the inverter firmware and its AC coupling
capability to be set. Once I update the Mate3s, I was able to
specify AC coupling. Thanks for all the suggestions and I know I
will be able to use them in other situations. Chris<br>

the microinverter system operating when the utility goes

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

<p class="MsoNormal">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? <o:p></o:p></p>

<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.<o:p></o:p></p>
<p>Garage has a MLO subpanel that is connected to
the multimode back up service panel that is in the
main building.<o:p></o:p></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.<o:p></o:p></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? <o:p></o:p></p>
