Thank you, It's pretty tight, I am hoping for some radio or wifi breaker to send a signal.  Just no luck yet. Chris

P.S.

You would need to run the control wires back to the inverter. Can you possibly run a pair of #16 wires the through the conduit feeding the building with the compressor?

Can you use a contactor with the coil wires connected to the AC IN of the Outback? When incoming AC goes down, the contactor will open to shed the compressor circuit.

    We installed a 4kW Outback multimode system about 8 years ago.  An
    electrician came in afterwards and installed 3 heat pumps on the
    battery backed up power panels.  The Outback inverter disconnected on
    load every time there was a power outage. The electrician really
    messed up and is long gone. Also found out did not pull a permit. But
    I digress.  We managed to move two of the heat pump circuit breakers
    to the utility panel, so no longer on the battery backed up power
    panels.  The third heat pump is the problem as it is located in an
    apartment building remote from the main house. The whole apartment
    subpanel, including the heat pump load  is interconnected to the
    "main" battery backed up power panel in the home.

    A master electrician and I are considering how to shed the apartment
    heat pump in a power outage.  We cannot easily run a separate circuit
    to the apartment building to pick up this load.  We have considered a
    smart panel, but the cost seems high for one circuit. Does anyone
    know
    of a power line product of RF product or similar that could operate
    this breaker when the main service panel loses power? I have been
    unsuccessful over months of sporadic research.

    Thanks in advance.
