How do inverters work in New Zealand?The most common inverter-based resources used in New Zealand rely on a high-quality system voltage waveform to determine the active and reactive power outputs that the inverter can generate. 2.23.
When will inverters be certified in Australia and New Zealand?In December 2020, the Standard was updated to reflect changing conditions in the industry. These changes could affect your business, so knowledge is key to minimise risk before transitioning to the updated version. In December 2021, all new inverters in Australia and New Zealand will need to be certified to AS/NZS 4777.2:2020.
What is a standard for inverter energy systems?Standard specifies safety and installation requirements for inverter energy systems (IES) intended for the injection of electric power through an electrical installation to the grid. IES are distributed energy resources when connecting to the grid and need to ensure overall safe operation of the installation and interaction with the broader grid.
Can inverters be legally installed in Australia or New Zealand?Inverter manufacturers will need to ensure their inverters comply with the updated Standard prior to the transition date. There is a chance that some inverters will become non-compliant if they cannot operate according to these setpoints, meaning they could not be legally installed in Australia or New Zealand until compliance is demonstrated.
How complex is New Zealand's power system?New Zealand’s power system is becoming increasingly complex to operate, as generation and energy storage system investments are made across transmission and distribution networks. The management of stable voltages across networks will increasingly require greater co-operation between the system operator and distributors.
How long will a weak transmission system last in New Zealand?Inadequate system strength may become an issue on New Zealand’s transmission network in 3–7 years. 2.21. A distorted voltage waveform can cause maloperation of inverter controls, resulting in inverter-based resources performing in a manner that is less desirable from a network operations standpoi
