Vehicle-to-grid (V2G) means the EV battery can send power back to the home or the grid, not just draw it. In Australia the question of which chargers are approved has three parts: product certification, vehicle compatibility and network permission. Each is separate.
Standards and certified products
Bidirectional charging is covered by AS/NZS 4777.2:2020 and AS/NZS 4777.1:2024. Reports indicate the Wallbox Quasar was the first charger certified against AS/NZS 4777.2:2020, and Sigenergy has a bidirectional DC charger that is reported to be CEC-approved when paired with its inverter. Other products, such as units from V2Grid and RedEarth, have also been reported. The market moves fast, so treat any list as a snapshot. Check the Clean Energy Council product list and the manufacturer’s current certification before you quote.
Network approval is the catch
Even a certified charger needs a distribution network service provider to accept the connection and, for export, to allow V2G. Approvals have been granted in some networks (South Australia and parts of NSW have been reported), while others are still working through technical rules. Always lodge the application early and confirm the export limit.
Vehicle compatibility
Only some EVs allow V2G, and the car maker’s warranty position matters. Vehicle-to-home and vehicle-to-load (power an appliance from the car) are simpler than full grid export. Ask the dealer for written confirmation that the specific model supports bidirectional charging with the chosen charger.
How V2G relates to rebates
The Cheaper Home Batteries Program covers stationary batteries of 5 to 100 kWh usable that are CEC-approved and VPP-capable. An EV is not a battery under the program, so a V2G setup does not earn STCs, and nor does the charger. If you also install a home battery, it can earn them under the normal rules. Rebates for chargers are separate: for example the federal DRIVEN stream for dealerships (explained here). For state offers see the rebates hub.
What this means for installers
V2G installs need electrical competence in bidirectional equipment and, usually, the manufacturer’s accreditation as well as your general licence. Photograph the installation, label plate and isolators, and keep the network approval with the job file. If you are installing a battery as part of the same project, the battery submission guide lists the evidence the regulator wants. When the battery claim is ready, see how settlement works and compare rates on pricing.
