Power Quality Response Mode Settings

New inverter settings

In December 2020, Standards Australia released a new version of AS/NZS 4777.2 Grid connection of energy systems via inverters Part 2: Inverter requirements (AS/NZS 4777.2:2020). The update saw a range of changes to improve the performance of inverters on the electricity supply network. These changes will support the continued increase of solar Photovoltaic (PV), batteries and electric vehicles. Inverter manufacturers have been working to update their products so they can undergo certification testing and listing with the Clean Energy Council (CEC) as 2020 compliant.

Amendments to the National Electricity Rules (NER), which commence on 18 December 2021 require all grid connected inverters to comply with AS/NZS 4777.2:2020.

The power quality settings in the new version are defined by region of installation: Australia A, B and C. The table below provides a list of the regions and the corresponding Distribution Network Service Provider (DNSP):
