Across Australia, over two million households now have rooftop solar photovoltaic (PV) installed. In South Australia alone, rooftop solar has contributed up to 77 per cent of the state’s energy needs at times. This shift, while positive for the environment, is also seeing a huge amount of pressure put on the grid [1][2].
“Solar is a popular energy source supporting a more sustainable Australia, but for it to reach its full potential, there needs to be strong guidance that can assist with the seamless conversion of the energy produced,” said Roland Terry-Lloyd, Head of Standards Development at Standards Australia.
To further support the use of inverters, in December 2020, Standards Australia published, AS/NZS 4777.2 Grid connection of energy systems via inverters, Part 2: Inverter requirements. Inverters feed and adjust energy going into the grid, making them essential tools for grid stability.
Nigel Wilmot, Senior Standards and Technology Engineer at Western Power said the update to the standard addresses the identified impacts on the electricity grid from the continuing uptake of inverter energy systems, particularly solar PVs, by customers.
“The changes will improve inverter performance and assist in maintaining a safe and stable supply for the community while continuing to use the renewable energy generated,” Mr Wilmot said.
Violette Mouchaileh, Chief Member Services Officer for the Australian Energy Market Operator (AEMO), added that AEMO welcomes the publication of the guidance, which she noted will assist in providing Australians with greater access to reliable and secure energy.
“Its successful development reflects strong collaboration between Standards Australia, government and industry,” Ms Mouchaileh said.
“Standards Australia looks forward to continuing to support the infrastructure and products needed to make renewable energy an option for more Australians,” added Mr Terry Lloyd.
