   Here's a possible answer.

   I designed a functionally similar circuit to wake my APC inverter when the   
   fridge wants to run. Mine requires some logic circuitry because it needs a   
   hack to handshake with the APC Start button and buzzer to wake it when on   
   battery power, so the start circuit is more complex than you need. APC   
   declares that waking on battery power, while possible, is not a "normal"   
   operation. They also scolded me for finding and using their "proprietary"   
   command language.   
      
   A current sensing relay will detect when the fridge shuts off and command   
   the APC to sleep, or it could return a genny to ECO if combined into Pete's   
   and Ron's circuit The relay has an LED that indicates when the fridge is   
   drawing current, which tells me to wait a few minutes when switching its   
   plug between grid and APC power.
