AS4777.2 2020 - WHAT YOU NEED TO KNOW
* The information below is intended for guidance purposes only. While Supply Partners has consulted with various organisations in preparing the below summary, we do not warrant that the information given is complete and error-free. We recommend that installers undertake their own enquiries based on their own business circumstances, including verifying this information with the appropriate regulators.
A: The key changes in AS/NZS 4777.2:2020 standard taking effect on the 18th of December 2021 are intended to improve grid stability. This includes new requirements around power quality response modes such as Volt-Var and Volt-Watt, new region settings for grid parameters, changes to export limiting requirements, inverter documentation and more.
A: AS/NZS 4777.2:2020 was officially released in December 2020 with an implementation date of December 18th 2021. Most inverter manufacturers were on track for compliance to the new standard however on November 22nd 2021, The Electrical Equipment Safety System Standing Committee (EESS SCO EWG) released two bulletins which outlined requirements for the certification of DC isolators for use in solar PV installations and a new process for testing facilities to be considered an “approved testing entity”. Currently there are no testing facilities that can test to these updated requirements and likely won’t be until late January 2022. This has caused unforeseen delays to the approval process less than one month from the required compliance date. For any manufacturer that had approvals issues prior to the 22nd of November it was under the old requirement. There is no information at this time to suggest that these approvals will be revoked.
A: On the 14th of December 2021, the Electrical Regulatory Authorities Council (ERAC) and the Standing Committee of Officials (SCO) of the Electrical Equipment Safety System (EESS) released a joint statement extending the DC isolator compliance requirements until June 30th 2022 to allow sufficient time for testing facilities to certify the inbuilt DC isolators to AS 60947.3:2018. It is important to note that even though the compliance date for the inbuilt isolators has been extended, the requirement of approval to AS/NZS 4777.2:2020 has not been extended. Installers will need to ensure the product they are installing is on the CEC approved list from December 18th 2021 and follow any guidance issued by the manufacturer in relation to firmware updates and setting adjustments where applicable.
A: From December 18th 2021, only inverter models with approval to AS/NZS 4777.2:2020 will remain on the approved list. Under the new standard inverters are required to have Region A, B, or C setpoints for grid settings within Australia. STC traders will be requesting photographic evidence of the region setting applied in the inverter as if the setting is not available it may mean that the inverter hasn’t been updated or is non-compliant.
A: If the manufacturer has declared the inbuilt isolator complies with AS 60947.3:2018 and external isolator adjacent to the inverter will not be required.
A: Supply Partners recommends regularly monitoring the approved list of inverters, ensuring you are on the mailing list of the inverter manufacturers you promote and maintaining a good line of communication with your supplier. We will continue to add new information from our inverter partners and even manufacturers we do not sell to our rolling coverage as we feel it is in the best interest of the industry to share all the information available in a central location.
INVITE TO ALL INVERTER MANUFACTURERS IN AUSTRALIA
We're inviting all manufacturers who offer Inverters in Australia to send through their statement regarding AS4777.2:2020 Compliance and we will publish it on this page. Even if it is from a brand that we don't distribute, we will share it as we want to include as much helpful information as possible. Please email your statement to email@example.com.

Sungrow have provided an update on their range and compliance statuses relating to AS/NZS 4777.2:2020 & AS 60947.3:2018
Update: 16/12/21 . All of these inverters except for SH5K-30 should now be on the CEC approved list. An official statement will soon follow from Sungrow.
13/12/2021 - Update from Sungrow Regarding Compliance to AS/NZS 4777.2:2020
Excerpt from Statement:
As Clean Energy Council’s newsletter said:’ The solar industry has been thrown into disarray by recent changes made by electrical safety regulators to the certification system and other paperwork for DC isolators.’, Sungrow inverters’ built-in DC isolators cannot receive the new AS 60947.3 certificate and it cannot be registered on the EESS level 3 category before 18th December 2021 due to the new regulations issued by EESS and no approved testing entity at this stage even Sungrow already did the relevant test and passed all testing items.
In order to acquire the AS/NZS 4777.2:2020 certification and be approved by Clean Energy Council in time, we are now resorting to removing the integrated DC isolator from our household inverter entirely.
Please see the statement to review the current status of each Sungrow Inverter model.
14/12/2021 - Important Update from ERAC and EESS Regarding Extension Period
As of 4PM Tuesday 14/12, the CEO of the Smart Energy Council, John Grimes, has shared an update from ERAC and EESS with resolution to the DC Isolator Issue. Please review the statement for details.
13/12/2021 - Update from Delta Electronics - AS4777.2:2020 Product Updates
From DELTA: Inverters being re-certified that are already in distributors stock will require a firmware update to achieve compliance to AS4777.2:2020. A detailed procedure on how to do this will be provided at a later stage once the certification process has been completed. New inverters from factory post-certification will already have the latest firmware and will have its external sticker updated showing compliance to AS4777.2:2020.
Current changes to compliance processes are providing alternative pathways given the current global DC Isolator certification issues at hand while also not compromising on safety. These issues are affecting a large portion of inverter manufacturers in Australia and the issue is being hotly debated by regulatory bodies during this time. Delta aims to keep our sales partners in the loop as much as possible to be able to deliver a safe and compliant product in a timely manner.
08/12/2021 - Update #2 from GoodWe on Compliance - ASNZS4777 & AS60947
08/12/2021 - Update #2 from Fronius on Inverter Compliance - AS_NZS4777.2_2020
From Fronius: Please click the download link to view the guide to update the software for Fronius Snap Inverters, and also the guide for the Gen24 inverters.
This should be done for all Fronius inverters when the installer is commissioning the inverter. Installers can start doing this as of now if they wish, however it is not compulsory until Dec 18th for AS 4777.2:2020 compliance.
For Gen24 inverters a USB update cannot be done. The instruction guide for the Gen24 inverters can also be found at the download like. It is a different but very easy procedure for the Gen24 inverters. The installer just needs to ensure the software file they use for the update is the latest software version. Then carry out the software update, and don’t just skip the software update process.
08/12/2021 - Update from SMA regarding AS/NZS 4777.2:2020 Compliance
From SMA: The December 18th deadline for inverter compliance to the new AS/NZS 4777.2:2020 standard is fast approaching.
The SMA team is working hard on compliance but are experiencing delays in the development, verification, testing and certification processes.
This is intermingled with a revised AS/NZS 5033:2021 standard released late November and further interpretation changes for DC isolators (AS60947:2018).
The following information can be accessed via our dedicated AS/NZS 4777.2:2020 Inverter Standard webpage.
Expected compliance dates for AS/NZS 4777.2:2020
The expected dates for each inverter series are now indicated on our dedicated
AS 4777.2:2020 webpage.
Compliance to AS60947 (DC Isolators)
The compliance to AS60947 (DC Isolators) requirements have been listed with links to certificates of conformance with the DC isolators tested in the inverters.
Export limiting accuracy
Export limiting accuracy is an important part of AS/NZS 4777.2:2020. Compatible, tested metering solution options are included for assurance export limiting meets the new requirements.
