What are the changes to inverter product standards?
On August 23 2024, Standards Australia published an update to AS/NZS 4777.2, the standards that cover product requirements for inverters.
AS/NZS 4777.2:2020 Amd 2:2024 can be downloaded for free here and includes key updates to:
- supply type terminology
- removal of IEC 62109 requirements for battery only products
- generation limit control parameters
- region C set points
- documentation and marking
- electric vehicle supply equipment (EVSE) specific clauses
In August, Standards Australia outlined a 12-month transition period for the new amendment with AS/NZS 4777.2:2020 Amd 2:2024 coming into effect on 23 August 2025.
What are the implications for inverters product list requirements?
The Clean Energy Council maintains a list of inverters that meet Australian standards and is working through implications of the new standards. Currently, we have determined that:
- Currently listed inverters will not require re-testing to retain product listing. However, manufacturer and importers will need to demonstrate the update to the Australia C region settings in line with Amendment 2, by providing a certificate of modification or certifier declaration to the Clean Energy Council by 23 August 2025.
- Applications for inverter listings that meet either AS/NZS 4777.2 or AS/NZS 4777.2:2020 Amd 2:2024 standards will be accepted until 23 August 2025.
- From 23 August 2025, the CEC Clean Energy Council will only accept applications that meet the AS/NZS 4777.2:2020 Amd 2:2024 standard.
The Clean Energy Council continues to assess the change and impacts on product listings including the areas below. We will provide updates as they come to hand:
- Categorisation of Products in line with updated terminology
- Categorisation, testing, certification and subsequent listing of Electric Vehicle Supply Equipment (EVSE)
- Review of the current Terms and Conditions
