Updated product standard now in effect
AS/NZS 4777.2:2020 Amd 2:2024 came into effect on 23 August 2025 and non-compliant inverters have now been removed from the approved inverter list.
You can find out more about the standards change and what manufacturers needed to do to prove compliance below.
What were 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.
How the updated standard affected approved product list requirements
The Clean Energy Council maintains a list of inverters that meet Australian standards and determined that:
- Inverters that were listed before the standard change did not require re-testing to retain product listing. However, manufacturers needed to demonstrate that their relevant* products complied with AS/NZS 4777.2:2020 Amd 2:2024, by providing a manufacturer declaration and supporting evidence as described below.
- Applications for inverter listings that met either AS/NZS 4777.2:2020 or AS/NZS 4777.2:2020 Amd 2:2024 standards were accepted until 23 August 2025. New categorisation of inverters and power conversion equipment (PCE) and the relevant standards have been added to the HOW TO APPLY section here. Manufacturers who chose to apply under AS/NZS 4777.2:2020 were also required to submit evidence of region settings in line with AS/NZS 4777.2:2020 Amd 2:2024 before 23 August 2025.
What happened from 23 August 2025?
- From 23 August 2025, the Clean Energy Council only accepts applications that meet AS/NZS 4777.2:2020 Amd 2:2024. This can be either through certification to AS/NZS 4777.2:2020 Amd 2:2024 or through certification to AS/NZS 4777.2:2020 plus a manufacturers declaration and evidence of region settings in line with AS/NZS 4777.2:2020 Amd 2:2024.
*This requirement does not apply to stand-alone inverters that do not connect to the grid.
How manufacturers were required to provide evidence of updated region settings
Manufacturers with relevant* inverters on the Clean Energy Council’s approved products list were required to provide confirmation of compliance with 4777.2:2020 Amd 2:2024 before the updated standard came into effect on 23 August 2025.
*This requirement does not apply to stand-alone inverters and other power conversion equipment (PCE) that do not connect to the grid.
Confirmation should be supplied by email to products@cleanenergycouncil.org.au with:
- A manufacturer declaration on your company's letterhead asserting that all relevant models comply with AS/NZS 4777.2:2020 Amd 2:2024 for listed inverters. A template can be found here.
- Supporting documentation showing the updated region settings for all models included in the declaration, either as a product document such as an installation, a user manual or as a screenshot of a monitoring app for the product.
Attachments should not exceed 5MB. If greater than 5MB of attachments is required for supporting documentation, please notify the Products Team.
What happened if manufacturers did not provide evidence of updated settings?
Any relevant inverter for which a declaration was not provided by the manufacturer as above, and that was not verified by the Clean Energy Council, was removed from the Approved Inverter List on 23 August 2025.
After 23 August 2025, should the Clean Energy Council find evidence that an inverter model is not compliant with 4777.2:2020 Amd 2:2024 where relevant, it may be removed from the approved inverter list.
Bi-directional EV charging and inverter listings
The updated standard contains electric vehicle supply equipment (EVSE) specific clauses with implications for inverter product listings
AS/NZS 4777.2:2020 Amd 2:2024 contains clauses that allow for mode 3 and mode 4 bidirectional electric vehicle charging.
Mode 4 charging enables electricity to flow to and from the vehicle and is controlled by Electric Vehicle Supply Equipment containing an inverter on the wall. These products fall under AS/NZS 4777.2 where they are for connection to the electricity grid and are in scope of the Clean Energy Council’s approved inverter list.
Mode 3 charging enables electricity to flow to and from the vehicle but is controlled by an inverter within the car. We are resolving to what extent the components of this system should be covered by the approved inverter list and processes for reviewing applications.
