Output AC Specifications

The  PVI  3000S-5300  is  designed  to  feed  power  into  a  standard  60Hz,  240  or  208V  AC  utility
service or 208V AC provided within a facility by a step down transformer (for example, from 480V
AC  service).    As  required  by  NEC,  there  must  be  a  dedicated  2-pole  circuit  breaker  for  the  PV
inverter  connection.    This  circuit  breaker  (and  wiring)  must  have  a  rating  of  20,  25  or  30A
depending  on  the  model.    The  inverter  is  designed  to  work  with  the  range  of  AC  voltage  for  a
240VAC or 208V service defined by UL1741/IEEE1547.
