What I have done for off grid use is to cut 1 wire going to the AUTO 
side of the switch (a DPDT), install a 12 volt relay n/o contacts in 
series with that wire, then leave the switch in AUTO. When the Outback 
calls for generator, the relay closes and the generator takes over like 
you put it in AUTO. This solution leaves the MAN and OFF position  for 
local control. It has worked for me on many Generacs. Of course, this 
will not work with line voltage present.
