Inverter Integrated DC Isolators - Australian Certification Extension Period to 30 June 2022

The requirement date in South Australia for DC isolators to be certified, where they are integrated in inverters complying with AS/NZS 4777.2:2020, has been extended to 30 June 2022.

During this extension period, inverters complying with AS/NZS 4777.2:2020 may be sold or installed, whether or not the DC isolator within the inverter is certified.

From 19 December 2021, all inverters installed must comply with AS/NZS 4777.2:2020 (including the requirement that an inverter's integrated DC isolator complies with AS 60947.3:2018).

Inverters compliant to the new AS/NZS 4777.2:2020 standard can be found on the Clean Energy Council website – click here

It is anticipated that from 19 December 2021, the list of compliant inverters will grow, including models with integrated DC isolators.


Electrical safety regulators will continue to work with industry, test facilities and accredited certifiers, to ensure suitable approved testing facilities are available to enable suppliers to obtain certification of DC isolators installed in inverters by 30 June 2022.

DC Isolators - Cancellation of Australian Certifications

Australian private certifier SAA Approvals recently cancelled 18 certifications for a range of DC isolators.

The cancellation of these certificates mean that the affected products can no longer be manufactured or imported into South Australia.

Energy Safety Victoria (ESV) has published further information about this issue on their website: click here

A list of affected models can also be found here.

The Office of the Technical Regulator is aligning with the advice issued by ESV.

Updated Smart Meter Wiring Requirements

A meter installation is required to comply with the Technical Regulator Guideline - Smart Meter Minimum Technical Standard and associated Deemed to Comply Wiring Arrangements (PDF 1.1 MB).

The guideline specifies the ‘Smart Meter Minimum Technical Standard’ and the ‘Deemed to Comply Wiring Arrangements’, which is applicable to Metering Coordinators, Metering Providers and Electrical Contractors.

Recording Electrical Test Results

The Office of the Technical Regulator has developed testing and verification information to help with recording test results:

The visual inspection form, the test schedule and a copy of the eCoC are required for reconnecting the electricity supply.

Important information for Solar Installers 

From Monday 28 September 2020 the Smarter Homes regulatory changes apply.

 These place several new requirements on installers including:

  • Installing only approved inverters
  • Ensuring that electricity generating plants can be remotely disconnected
  • Wiring meters in accordance with an OTR wiring guideline

 Information about these changes, and how they affect you can be found on the Information for Installers page.
