Canberra Sine Wave Inverter BESS

Can a battery energy storage system connect with a grid-forming inverter?

This fact sheet contains information relevant to parties seeking to connect battery energy storage systems (BESS) with grid-forming inverter capabilities within the National Electricity Market (NEM), as of December 2022.

What are inverter-based energy resources?

ble energy resources—wind, solar photovoltaic, and battery energy storage systems (BESS). These resources electrically connect to the grid through an inverter— power electronic devices that convert DC energy into AC energy—and are referred to as inverter-based resources (IBRs). As the generation mix changes, so do the electrical character

What is the Big Canberra battery transformer?

This stored energy will be used to support our electricity grid. The Big Canberra battery transformer was delivered to the Williamsdale site in early September 2025. The transformer ensures electricity stored in the battery is converted to the correct voltage to be safely supplied to the grid.

Should I Retrofit a Bess inverter?

Not ideal for retrofits. Required to replace existing inverter and in many cases PV array wiring need to be reconfigured Higher efficiency as the power is not inverter multiple times. Fewer components. Short cables between BESS and PV reduces losses
