New Inverter Standards In Australia 2021!

New Inverter Standard in Australia

We recently received the news that the standards regarding the solar inverters in Australia are about to undergo a major change soon. The AS/NZS 4777.2:2020 version of solar inverter standards will replace the AS/NZS 4777.2:2015 version, starting from the 18th of December 2021. All the solar inverters that will be installed from 18th December 2021 must comply with the new version of the inverter standard. 

Here, at Compare Solar Quotes, it is our duty to provide the people with the correct and accurate information about solar power systems in Australia. Our expert team works diligently 24/7 to help the Australian people with all sorts of solar-related problems and queries. In this guide, we will help you to get a better understanding of the new inverter standards in Australia. 

Before we get into a discussion about the new inverter standards, let us know the basics about solar inverters. A solar inverter is one of the two mandatory components of a solar power system. A solar inverter is designed to convert the DC electricity generated by the solar panels to AC electricity, making solar energy usable for household appliances. 

The new change of the inverter standards has implications for registered personnel, solar agents, solar retailers, and, last but not least, solar installers. In short, it has implications on everyone in relation to the production of small-scale technology certificates (STCs). In order to be eligible for the small-scale technology certificates, solar inverters have to meet the inverter standards of Australia and New Zealand. These solar inverters will also have to be listed on the approved inverter list of the Clean Energy Council (CEC)

This means that any solar power system installed after 18th December 2021 will have to meet the new AS/NZS 4777.2:2020 version of solar inverter standards. The installed solar inverters that meet the inverter standard AS/NZS 4777.2:2015 version will no longer be eligible for the STCs, starting from 18th December 2021. 

What does this new change in Inverter Standards mean for customers?

Australia is currently in a transition period where solar inverters that comply with both versions of inverter standards are eligible for the STCs. During this time of transition, we encourage solar installers, agents, and retailers to manage their stock of inverters properly and carefully. Because in order to be eligible for the STCs, all solar inverters installed from 18th December 2021 must be listed in the 2020 approved list of solar inverters of the Clean Energy Council. 

Solar retailers and installers must also regularly keep up with the approved list of inverters by the CEC to know about the expiry dates of inverters. Solar agents have the responsibility of ensuring that solar installers only install the eligible and approved inverters and include them in the STC claims. This step prevents the incorrect creation of small-scale technology certificates. 

The Clean Energy Regulator detects the use of ineligible solar inverters under the small-scale renewable energy scheme (SRES) and applies a broad range of compliance and enforcement options. This can result in the suspension of registration, enforceable undertakings, and criminal or civil proceedings.

While processing the STCs, the Clean Energy Regulator requires the STC claims to include eligible solar components that comply with the standards of Australian and New Zealand solar components. In order to differentiate between the solar inverters that comply with the 2015 and 2020 versions of inverter standards, CEC is adding (AS4777-2 2020) suffix to the model numbers of inverters that comply with the 2020 version. 

All the inverters that comply with the 2015 version of the solar inverter standards will be listed as expired in the approved list of inverters by the Clean Energy Council. Installation of any expired inverter from 18th December 2021 will no longer be eligible for the STCs. These inverter standards are also applicable for inverters used in off-grid solar power systems. 

How to enter the correct Inverter Information in the STC claim?

Each and every solar agent must make sure that they are collecting and recording the proper and right information about the eligible inverters. Solar retailers and installers must check with their solar inverter supplier and ensure the standards that the inverters meet. They must be able to provide you with the correct and accurate information. 

We expect all the solar agents to have a certain procedure of ensuring that only the eligible solar inverters are being installed and included in the STC claims. While submitting your STC claim, make sure that you reference the installed eligible solar inverter exactly as listed in the approved inverter list of the Clean Energy Council. This reference must also include the suffix that the Clean Energy Council added to the inverter list where appropriate. 

Conclusion:

Solar power systems are becoming an essential part of our lives with each passing day. It is essential for us to be aware of the rules and standards of solar components. If you are going to install a solar power system soon, make sure you choose a solar inverter that meets the new 2020 version of the invert standards in Australia and New Zealand.
