  1. PV Inverter
  • Is the photovoltaic (PV) system utility-interactive or standalone? 690.2
  • Is all the equipment listed for PV application? 690.4
  • Is the system grounded or ungrounded? (if ungrounded, the system needs to comply with 690.35)
  • Has DC Ground-Fault Protection been provided and properly labeled? 690.5 and 690.35(C)
  • What is the maximum PV system voltage? 690.7
  • Is all listed equipment rated for the maximum voltage? 690.7
  • Determine the maximum circuit current for the PV Source and Output Circuit; Inverter Output Circuit; Stand-Alone Inverter Input Circuit; and DC to DC Converter Output (refer to inverter documentation)
