Australia A

When installing a rooftop solar system, it is critical that you install an approved smart inverter and set it correctly.

Solar and battery inverters in Victoria must be installed with AS/NZS 4777.2:2020 Australia A settings.

A review by the Australian Energy Market Operator found many inverters are being installed to incorrect inverter settings, this is why we’re introducing new requirements for solar installations on the CitiPower and Powercor networks.

Step 1: Once a new system is installed, use the inverter manufacturer’s app or portal to commission the system. Download a copy for Step 2.

Step 2: Attach evidence of your commissioning documentation to your Solar Alteration Application. This demonstrates the inverter has been set to “Australian A” and therefore compliant with Australian Standards.

Any of these forms of evidence are accepted:

• the copy of the commissioning sheet from the inverter manufacturer (make sure it includes the grid settings and inverter serial number)
• a photo of the inverter screen showing both the inverter serial number and the grid settings
• a screenshot of the commissioning process that shows both the inverter serial number and grid settings.

Step 3: We will validate the commissioning evidence at the same time as we check the Certificate of Electrical Safety.

Step 4: Once both the Certificate Of Electrical Safety and Commissioning evidence are validated as compliant, your Solar Alteration Application will be processed, to ensure your customers meter is reprogrammed for them to receive their feed-in tariffs.

What’s next?

Your application will remain on hold pending upload of the new commissioning documentation and closure of your call to action. Failure to complete this action means your customer will not receive their feed-in tariffs.

Why are we doing this?

Our role is to make sure all forms of customer energy resources are integrated safely and seamlessly into our network.

Getting the settings right on all new smart inverter installations is essential. It supports current and future customers to get the most out of their solar PV systems. We want to work with the solar industry to make this happen.
