Thank you, I did find their website and seeing if it has a chance. Chris

There is a company called Savant, I’ve seen their individual Smart
breakers installed in sqd Panels - they are individual smart breakers.
A single pole breaker would actually take up two slots one for the
OCPD itself, and one for the sp relay. Don’t know exactly how it
operates, but I know you don’t have to buy an entire smart panel for
it to work.
As discussed on this forum, also, there are also RF transmitter/
receivers, which can do what you ask. Used them to disconnect an
inverter from a common AC bus when the gennie turns on.

Hi Chris,
I’m wondering if a load management device like this could be
helpful? However, it does not discern between grid presence and
island mode, so it might not fit the bill.

Quick caveat that shedding an HVAC unit potentially mid cycle is
not ideal for the health of that unit…but neither is an overload
and subsequent power failure.
I do know that Lumin Smart sells remote CTs for grid detection.
Might be worth a call to them to see if this fairly
inexpensive product can pair with a remote contactor to open the
HVAC circuit.
Best of luck!

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.
Chris
