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

[Glenn Burt]

Run a branch circuit from the utility powered main service panel to the garage. Use this to power a contactor that will drop out on loss of grid, controlling one leg of the microinverter input to the AC coupled system.-GlennSent from my 'smart'phone, so please excuse typos and spelling errors.------ Original message------From: Christopher WarfelDate: Tue, Nov 23, 2021 10:24 AMTo: re-wrenches at lists.re-wrenches.org;Cc: Subject:[RE-wrenches] Rapid Shutdown Control for a System for a Multimode System Adding an Array to a Subpanel in Garage
    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
