Ensuring inverter settings are compliant
More and more customers are seeking renewable energy options to power their homes. As a result, an increasing amount of rooftop solar PV and batteries are being connected to the grid. To maintain grid reliability in the coming years, it’s important to comply with inverter standards now. This includes correctly installing and configuring invertor systems.
Australian Standards for inverters (AS/NZS4777.2) have recently changed. The changes will help ensure grid stability as increasing numbers of solar and battery systems connect to the network.
From 18 December 2021, all solar and battery inverters in Victoria must be installed with AS/NZS4777.2:2020 Australia A settings.
How to select the correct settings for inverters
To correctly configure solar PV and/or battery inverter settings in Victoria, follow the steps below:
- Make sure the inverter has the latest firmware installed.
- Select your country/region. Some manufacturers may have this pre-selected.
- Select the ‘AS/NZS 4777.2:2020 Australia A’ setting through the relevant section in the inverter app or display screen.
- Turn on the device.
- Once the system has been installed, use the inverter manufacturer’s app or portal to commission the system.
The diagram above shows an example of this process; however, this may differ depending on the inverter manufacturer.
Sometimes inverter manufacturers may need to remotely adjust inverter settings. This is to comply with technical and safety obligations. To allow this, the remote access on your inverter needs to be activated. It will ensure your connection is not interrupted and the grid continues to operate safely.
