Thanks to everyone, the setting I had said AC coupling No. I did not
realize that a firmware upgrade could enable that. I think it is best
to try frequency shift for this particular case. Thanks again to
everyone. Chris

Hello Chris
Sorry for the slow response I foolishly took a couple of days of
vacation.
I see this system is on Optics. The GS4048A inverter can do AC
Coupling with frequency shift. It will need to be upgraded from the
current rev of 001.006.063 to 001.007.070 below is a link to that
firmware.

Once the new firmware is installed will need to change the default
Installer password of 1732 to a different 4 digit number after doing
so In the inverter you can go to the menu and enable AC Coupling.
Below are instructions for changing the default Installer Password.

please see S-16 in the manual above.

I too speak English as my native foreign language below is a link to

It has helped me to spoke more lucidly and communicate more better.

Chris you have my # if you have questions.

It was tough for me to figure out how to write my email and not make
it confusing.
What I am worried about is the microinverter system operating when the
utility goes down and the microinverters continuing to operate and
charge the batteries as a load. I need to disconnect the
microinverter circuit only 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.

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?

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.
Garage has a MLO subpanel that is connected to the multimode
back up service panel that is in the main building.
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.
Does anyone know of a product that could do this. I would
imagine a transmitter, or perhaps something else besides a
microinverter array?
Thanks for any help. Chris
