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.
Below is a link to the AC Coupling App Note

I too speak English as my native foreign language below is a link to
Fowlers Modern English Usage
It has helped me to spoke more lucidly and communicate more better.

Thanks for using OutBack
Chris you have my # if you have questions.
Have a good Thanksgiving and Stay Safe.

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
