Top 10 Safety and Quality Issues addressed on audit report as per annexure provided by Solar Victoria

• Mismatched DC Connectors - <br><br>Ensure only the same type/model from the same manufacturer are mated together for DC Connectors. <br><br>Ref: AS/NZS 5033:2014 Cl. 4.3.7(k)

  Pass

  Fail

  N/A

• Inadequate earthing - <br><br>Ensure that the PV array mounting frames and ALL modules have an equipotential earth bond connected to the earthing terminal on the switchboard/distribution board to which the inverter is connected, either directly or via the inverter main earth conductor.<br><br>Ensure the mandatory earthing tests are carried out to verify compliant earth continuity as per the Australian Standard.<br><br>Ref: AS/NZS 3000:2018 Sect 8.3.5 & AS/NZS 5033:2014 Cl. 4.4.2.1"

  Pass

  Fail

  N/A

• Water damage and signs of water ingress in the ground and roof DC isolator - <br><br>Ensure DC enclosure(s) at the array is are correctly installed to prevent water ingress, including appropriate IP rated cable glands and multi-hole sealing grommets to suit the number of installed cables, and if possible use external fixing points. Cables and conduits shall not enter the top entry face of the enclosure.<br><br>Ref: AS/NZS 5033:2014 Cl. 4.4.4.6

  Pass

  Fail

  N/A

• Entries to electrical enclosures (Protection of Connections) - <br><br>Ensure all conduit glands & fittings to the electrical enclosure are be installed and sealed in accordance with the manufacturer's instructions, including being glued if required.<br><br>Ensure glands are installed where required to maintain IP ratings and prevent strain on terminations.<br><br>Ref: AS/NZS 5033:2014 Cl. 4.4.4.6 & AS/NZS 5033:2014 Cl. 4.4.4.6"

  Pass

  Fail

  N/A

• Inverter not fixed correctly - <br><br>Inverters (PCEs) shall be installed in accordance with manufacturers' instructions.<br><br>Paying attention to minimum fixing sizes, number of fixings, locking devices, is the wall structurally sound for supporting the inverter, is the location acceptable and does it require an additional non-flammable barrier to be installed.<br><br>Ref: AS/NZS 3000:2018 Cl. 1.7.1(c) & AS/NZS 4777.1 Appendix C2.3

  Pass

  Fail

  N/A

• DC cables not enclosed in heavy-duty conduit or adequately supported -<br><br>Ensure all DC cables within the ceiling, wall or floor cavity are fully enclosed in heavy duty conduit or equivalent.<br><br>Joints in conduits and fittings should be glued to ensure fittings do not come apart exposing the DC cabling.<br><br>Ensure all wiring and conduit work is adequately supported by clips or saddles at regular intervals.<br><br>Ref: AS/NZS 5033:2014 Cl. 4.4.4.6

  Pass

  Fail

  N/A

• Max array voltage VOC greater than 600 VDC -<br><br>Ensure residential solar PV arrays are designed and installed to have a PV Array Max Voltage of less than 600 VDC. Remember, this is not the sum of the PV modules connected in series. The PV Array Max Voltage is calculated using the formula in AS/NZS 5033:2014 Cl. 4.2, which corrects the voltage for the lowest expected operating temperature.<br><br>Ref: AS/NZS 5033:2014 Cl. 4.2 & AS/NZS 5033:2014 Cl. 3.1

  Pass

  Fail

  N/A

• Mounting frames not installed to the Australian standards -<br><br>The PV mounting structure and attachments to the roof shall be installed in accordance with the manufacturer's instructions, ensuring it is secure and only approved components are only used, such as; mounting feet, rail joiners and correct end clamps to the array.<br><br>Ensure the PV mounting structure and attachments to the roof are secure by visually double checking to confirm all components are correctly fitted and tight.<br><br>Ref: AS/NZS 3000:2018 Cl. 1.7.1(c) & AS/NZS 5033:2014 Cl. 2.2.5"

  Pass

  Fail

  N/A

• Damage to the LV cables -<br><br>Ensure no LV cables have been damaged during the installation, ensure cables are clear of fixing screws when securing covers, components and panel clamps.<br><br>Ensure mandatory Insulation Resistance testing is carried out that may identify any damaged cables prior to energising, as per AS/NZS 3000:2018 Sect 8.3.6.<br><br>Ref: AS/NZS 3000:2018 Sect 8.3.6 & AS/NZS 3000:2018 Sect 3.94

  Pass

  Fail

  N/A

• DC isolators at the arrays are not correctly wired - <br><br>Ensure DC Isolators are correctly selected and rated for the connected voltage and prospective fault currents. DC Isolators must be wired in accordance with the manufacturers' instructions to ensure the internal contacts can safely operate the specified loads.<br><br>Double-check all terminals including links and bridges to ensure there are no loose connections, perform a pull test on each cable, and ensure all conductor strands have been captured and secured.<br><br>Ref: AS/NZS 5033:2014 Cl. 2.2.5 & AS/NZS 3000:2018 Cl. 1.7.1(c) & 3.7
