[RE-wrenches] Rapid Shutdown Control for a System for a Multimode System Adding an Array to a Subpanel in Garage

[Christopher Warfel]

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
