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. Further guidance on this will be provided in late February.
- Applications for inverter listings that meet either AS/NZS 4777.2:2020 or AS/NZS 4777.2:2020 Amd 2:2024 standards will be accepted until 23 August 2025. New categorisation of inverters and Power Supply Equipment (PSE) and the relevant standards has been added to the HOW TO APPLY section here.
- 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. We will provide a further update in February.
