Kurt,
The output (A/C) of the inverter can be installed in any approved raceway or 
cable assembly.  PVC (sch 80 if exposed) is an approved method.  The metal 
raceway rule only applies to the unfused D/C output of the array.  If you 
are installing a high voltage system, the voltage drop is similar for A/C or 
D/C. Either way would work.
