News and Notifications

Have you commissioned your inverter correctly?

The OTR has become aware of a number of solar and battery installations where inverters have not been correctly commissioned to the current Australian Standards.

AS/NZS 4777.2:2020 became mandatory in December 2021, and grid connected inverters are now required to be configured to AS/NZS 4777.2:2020 Australia A default settings.

New inverter installations are not permitted to be configured to AS/NZS 4777.2:2015 settings.

AS/NZS 4777.2:2020 introduced a range of important changes to the performance of solar and battery inverters, which are important to the stability of the grid and allow embedded generator installations to better manage disturbances seen on the grid. Rooftop solar is now in aggregate the largest generator in South Australia and it is critical to the future of solar that these operate predictably and reliably.

The OTR will be examining commissioning of inverters to ensure compliance, penalties will apply for non-compliant settings.

Important changes for all solar businesses

From Friday 1 April 2022, a range of new legal requirements apply to all solar PV installers, designers, agents, retailers, manufacturers, and importers who participate in the Small-scale Renewable Energy Scheme.

Find more information and resources on the Clean Energy Regulator website or call the Clean Energy Regulator on 1300 553 542.

Make sure to also share this information with your network, to ensure you can meet your new obligations.

2022 MASTER PLUMBERS SA Plumbing Roadshows

As we farewell last year and welcome 2022 its time to start thinking about the changes in the 2021 plumbing suite of standards AS/NZS 3500:2021 as they will affect the way you plumb.  

The changes to the AS/NZS 3500 suite will come into effect when the Plumbing Code of Australia (PCA) 2022 is released on the 1st of September this year. The PCA which is part of the National Construction Code (NCC) will also contain changes to backflow requirements and South Australian variations.

Thankfully the OTR and Master Plumbers South Australia are here to help, the dates and locations of the roadshows have been finalised and are listed on the Master Plumbers SA website.  Bookings will be mandatory so make sure you book in for a session with Master Plumbers South Australia via their website:

Important Changes for all Solar Installers/Designers, Agents and Retailers

From 1 April 2022 a range of new, mandatory requirements will directly affect solar installers/designers, agents and retailers whose work relates to claims for small-scale technology certificates (STCs) under the Small-scale Renewable Energy Scheme.

Find more information and resources about these requirements on the Clean Energy Regulator website or call the Clean Energy Regulator on 1300 553 542.

We encourage you to also share this information with your network of businesses, contractors and employees, to ensure you can meet your new obligations.

2022 NECA SA/NT Roadshows

NECA SA/NT and the OTR are pleased to announce the Roadshow Seminar Series is back in a COVID-safe way! The 2022 Seminar Series will be held across South Australia from March to June in 9 locations. Due to the current COVID-19 pandemic situation, a few changes have been made to the Seminar Series this year to protect everyone who attends these shows so we are running a reduced number of seminars spaced out over a longer period.

We highly encourage all electrical contractors and their workers to attend to ensure they are up-to-date with all the latest developments within the industry. The seminars will cover updates to Australian Standards, solar and isolator requirements, common compliance issues, the new Service and Installation Rules book, the new NECA Certified Contractor program and much more.

This annual seminar series is a significant training resource for the electrotechnology industry. The event this year is designed to provide licensed electricians with a greater understanding of the following topics:

  • NECA SA/NT on the new Certified Contractor program
  • SA Power Networks on the new Service and Installation Rules book
  • Office of the Technical Regulator on updates to Australian Standards, solar and isolator requirements, clarification on common issues, FAQs and more.

To attend the NECA 2022 Roadshow Seminar Series, please register via Eventbrite here:

Alternatively, you can visit, click on the Roadshow banner and complete the hard copy registration form.

Draft Dynamic Export Guidelines Published

From 1 December 2022 new solar installations connected to the distribution network in South Australia will be required to be capable of setting limits to the amount of energy exported to the distribution network, and for these limits to be able to be updated remotely.

The OTR has recently published a draft guideline document available on the Regulatory Changes for Smarter Homes website.

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.
