   You could manage without the expensive transfer hook-up, but one would   
   have to be very, very meticulous with how the system was engaged.  On   
   the order of a pre-flight check-list.  It would have to be installed on   
   the load side of the main breaker, though.   
      
   Main off           - check   
   All loads off      - check   
   Connect tickler    - check   
   Turn on tickler    - check   
   Turn on small load - check   
   (resistive)   
   Enable solar input - check   
   Enable other loads - check   
      
   Reverse procedure to disable.   
      
   Of course any line side interface would need a means of isolating the   
   normal system if sensing is before the main breaker.  Solution: Move   
   sensing after main breaker (should be this way, anyway).
