Note:  Production  meter  #2  needs  to  be  energized  all  of  the  time  for  meter  reading,  therefor  the  load  side  of  the  meter  socket  needs  to  be  connected  to  a  two  pole  breaker  in  the  sub  panel.  This  will  allow  the  meter  to  be  energized  from  either  source.  There  is  a  disconnect  relay  in  the  inverter  that  keeps  the  circuit  from  backfeeding  into  the  inverter.
