Marking



Modules. Modules shall be marked with identification of terminals or leads as to polarity, maximum overcurrent device rating for module protection, and with the following ratings:
  1. Open-Circuit voltage

  2. Operating voltage

  3. Maximum permissible system voltage

  4. Operating current

  5. Short-circuit current

  6. Maximum power


Alternating-Current Photovoltaic Modules. Alternating-current modules shall be marked with identification of terminals or leads and with identification of the following ratings:
  1. Nominal operating ac voltage

  2. Nominal operating ac frequency

  3. Maximum ac power

  4. Maximum ac current

  5. Maximum overcurrent device rating for ac module protection


Direct-Current Photovoltaic Power Source. A marking for the direct-current photovoltaic power source indicating items (1) through (4) shall be provided by the installer at an accessible location at the disconnecting means for this power source:
  1. Operating current

  2. Operating voltage

  3. Maximum system voltage

  4. Short-circuit current


Interactive System Point of Interconnection. All interactive system(s) points of interconnection with other sources shall be marked at an accessible location at the disconnecting means as a power source with the maximum ac output operating current and the operating ac voltage.

Photovoltaic Power Systems Employing Energy Storage. Photovoltaic power systems employing energy storage shall also be marked with the maximum operating voltage, including any equalization voltage and the polarity of the grounded circuit conductor.

Identification of Power Sources


Facilities with Stand-Alone Systems. Any structure or building with a photovoltaic power system that is not connected to a utility service source and is a stand-alone system shall have a permanent plaque or directory installed on the exterior of the building or structure at a readily visible location acceptable to the authority having jurisdiction. The plaque or directory shall indicate the location of system disconnecting means and that the structure contains a stand-alone electrical system.

Facilities with Utility Services and PV Systems. Building or structures with both utility service and a photovoltaic system shall have a permanent plaque or directory providing the location of the service disconnection means and the photovoltaic system disconnecting means, if not located at the same location.
