Electric vehicles (EVs) in Australia are rapidly evolving beyond just transport, transforming into powerful, mobile energy storage systems for your home and the grid. In 2026, bidirectional charging technologies – Vehicle-to-Load (V2L), Vehicle-to-Home (V2H), and Vehicle-to-Grid (V2G) – are becoming increasingly accessible, offering the potential to significantly reduce your electricity bills by up to $2,500 annually and enhance your energy independence.
This comprehensive guide will break down what these technologies mean for Australian households, which EVs and chargers support them, and the real costs and benefits involved in turning your EV into a home powerhouse.
What is Bidirectional EV Charging?
Bidirectional charging allows energy to flow both ways: into your EV battery and back out again. This capability is categorised into three main types:
- Vehicle-to-Load (V2L): This is the most common and accessible form. Your EV acts as a portable power bank, allowing you to plug appliances directly into an AC outlet (typically 2.2-3.6kW) built into the car or via an adapter. It’s ideal for camping, power tools, or emergency backup for small devices.
- Vehicle-to-Home (V2H): A more advanced setup where a bidirectional charger draws power from your EV battery to supply electricity directly to your home’s circuits. This can power your entire house during a blackout or help you self-consume excess solar generation, reducing reliance on the grid during peak times. V2H is now officially legal and available across Australia with the finalisation of Australian Standard AS/NZS 4777.1:2024.
- Vehicle-to-Grid (V2G): The most sophisticated application, V2G enables your EV to export stored energy back to the wider electricity grid. This can earn you credits or payments from your energy retailer, especially during periods of high demand and high electricity prices. The Australian Energy Market Commission (AEMC) cleared the regulatory path for V2G in late 2024, making it legal and operational in Australia.
“Vehicle-to-grid technology means your car does not just get you from A to B, it can help power your home and support the grid.” – Federal Energy and Climate Minister Chris Bowen, May 2026.

| Nissan Leaf (new 2026 model) | Yes (1.5kW) | Likely (details for AU pending) | Likely (details for AU pending) | New model arriving in Australia between April 2026 and March 2027. |
| Tesla Model 3 & Y | No (officially) | Limited (select 2025/2026 builds, via third-party chargers like RedEarth Ambibox) | No (officially) | Tesla Model Y was Australia’s best-selling car in May 2026. |
Note: V2G/V2H functionality on many newer EVs often depends on specific firmware updates and manufacturer warranty support, which are still evolving in Australia. Always confirm with your dealer and charger supplier.

Bidirectional EV Chargers: Products and Costs (2026)
Standard EV home chargers typically cost between $500 and $2,000 for the unit, plus $700 to $1,300 for installation, averaging around $2,269 nationally as of June 2026.
Bidirectional chargers, however, are more complex and therefore more expensive. Expect to pay a premium for this advanced technology.
| Charger Model | Type | Power Output | Estimated Unit Cost (AUD) | Key Features (Australia 2026) |
|---|---|---|---|---|
| Wallbox Quasar 2 | DC Bidirectional | 11.5kW | ~$6,000 - $10,000+ | CCS2 compatible, blackout mode, integrates with home energy systems. |
| Sigenergy SigenStor | Hybrid System (Solar, Battery, EV) | 12.5kW / 25kW | ~$10,000+ (as part of system) | Modular, CEC approved, direct DC charging from solar. |
| RedEarth Ambibox DC Wallbox | DC Bidirectional | Up to 22kW | ~$9,990 (plus GST) | Australian-made, supports CCS2 & CHAdeMO, used in trials with various EVs. |
| V2Grid Numbat | DC Bidirectional | 7kW (single phase) | ~$10,000 (plus GST) | First CEC certified bidirectional charger in Australia, wall-mounted. |
| StarCharge Halo V2G | DC Bidirectional | 7.4kW / 11kW | Pricing TBC | AS 4777.2 certified, awaiting CEC product listing. |
Installation costs for bidirectional chargers will be higher than standard chargers due to their complexity and integration requirements, often starting from around $1,000 on top of the unit cost, and potentially more for complex setups.

The Benefits: Why Turn Your EV into a Home Powerhouse?
- Lower Electricity Bills: By charging your EV when electricity is cheap (e.g., off-peak or with surplus solar) and discharging during expensive peak times, you can drastically cut your household energy costs. Amber Electric customers in V2G trials are projected to save up to $2,500 annually.
- Backup Power During Blackouts: Your EV can act as a substantial home battery, providing critical backup power during grid outages. A typical EV battery (60-80kWh) can power an average Australian home for 3 to 5 days, far exceeding the capacity of many fixed home batteries.
- Optimise Solar Self-Consumption: If you have rooftop solar, V2H allows you to store excess daytime solar energy in your EV and use it to power your home at night, maximising your solar investment.
- Earn Income from the Grid (V2G): Participate in Virtual Power Plant (VPP) programs and earn payments by exporting power to the grid during peak demand. Programs like ActewAGL/AGL Smart Home in the ACT have shown net annual benefits of $800-$1,800 for participants.
- Grid Stabilisation: Aggregated EV batteries can help stabilise the national grid, especially as more renewable energy comes online, reducing reliance on fossil fuel ‘peaker’ plants. This is a key focus of ARENA’s Driving the Nation program.
Australian V2G/V2H Programs and Trials (2026)
Australia is seeing significant movement in bidirectional charging trials, paving the way for wider commercial rollout:
- Amber Electric: With an additional $13.6 million in ARENA funding, Amber is expanding its V2G trial to 1,000 households, with an initial focus on BYD vehicles.
- ActewAGL / AGL Smart Home (ACT): Residents with compatible vehicles (e.g., Nissan Leaf, Kia EV9) and Wallbox Quasar 2 chargers can join managed export programs, earning above feed-in tariff rates.
- Origin Energy & AGL: Both major retailers announced V2G trials commencing in 2026, partnering with brands like Kia, Hyundai, Zeekr, and BYD.
- SA Power Networks (SAPN): Ran a V2G trial with CHAdeMO vehicles in South Australia, demonstrating grid stability benefits, with commercial expansion planned for 2026-27.
These programs are crucial for addressing challenges like manufacturer warranty concerns and large-scale deployment.
The Investment: Is Bidirectional Charging Worth It in 2026?
With bidirectional chargers costing upwards of $6,000 to $10,000 before installation, the initial outlay is substantial. However, the long-term savings and benefits can be compelling:
- Reduced Energy Bills: Potential savings of $800 to $2,500 annually through smart charging and V2G participation.
- Enhanced Energy Resilience: The peace of mind during blackouts, knowing your home can be powered for days by your EV. For comparison, explore Best Home Batteries Under AUD$10,000 in Australia 2026: Value, Features & Real-World Performance.
- Maximised Solar Value: Greater self-consumption of your solar energy, reducing your import from the grid. This integrates seamlessly with Smart Home Energy Systems: Slash Your 2026 Australian Electricity Bills by Up To 30%.
The return on investment will depend on your electricity consumption, solar generation, EV usage patterns, and participation in V2G programs. As the technology matures and costs potentially decrease, and as more manufacturers offer native bidirectional support, the value proposition will only strengthen.
Bottom Line
Bidirectional EV charging, particularly V2H and V2G, is no longer a futuristic concept in Australia; it is a tangible reality in 2026. While the upfront cost for a compatible EV and bidirectional charger remains a significant investment, the potential for annual savings of up to $2,500 on electricity bills, coupled with enhanced energy independence and grid support, makes it a compelling consideration for forward-thinking Australian EV owners. The market is maturing rapidly, with more compatible vehicles and chargers entering the market, and government-backed trials expanding, indicating a strong future for your EV as a true home powerhouse.
