For Australian homeowners in 2026, Vehicle-to-Home (V2H) technology is already a practical and valuable investment, offering immediate energy bill savings and blackout resilience. Vehicle-to-Grid (V2G) is emerging rapidly, with regulatory frameworks established and significant trials underway, but its widespread financial benefits for individual households are still maturing beyond V2H capabilities.
Your electric vehicle (EV) is more than just transport; it’s a substantial battery on wheels, typically holding 50kWh to 100kWh of energy. This is far greater than most standard home batteries, which usually range from 10kWh to 13.5kWh. Harnessing this capacity through bidirectional charging can profoundly impact your home’s energy consumption and resilience.
What is V2G, V2H, and V2L?
It’s crucial to understand the distinctions between these terms:
- Vehicle-to-Load (V2L): This is the simplest form, allowing you to plug appliances directly into your EV via a built-in AC outlet or adapter. It’s widely available on many popular EVs like the Hyundai IONIQ 5/6, Kia EV6/EV9, BYD Atto 3, Seal, and MG4, providing 2.2kW–3.6kW for powering tools, camping gear, or essential appliances. No special home installation is required.
- Vehicle-to-Home (V2H): This allows your EV to power your home’s circuits, functioning like a large home battery. A bidirectional charger draws power from the EV and feeds it into your house, reducing reliance on the grid, especially during peak price periods or blackouts. V2H does not require grid permission, only a compliant charger and installation.
- Vehicle-to-Grid (V2G): This extends V2H by enabling your EV to export power back to the main electricity grid. You can charge your EV when electricity is cheap (e.g., with solar or off-peak rates) and sell power back to the grid when demand and prices are high, potentially earning credits on your bill. V2G requires a compatible EV and charger, approval from your Distribution Network Service Provider (DNSP), and a suitable energy retail contract.
Current State of V2G/V2H in Australia (2026)
Bidirectional charging is rapidly moving from trials to commercial reality in Australia. The regulatory path for V2G was cleared in late 2024 by the Australian Energy Market Commission (AEMC), with updated Australian Standards (AS/NZS 4777.2 and AS/NZS 4777.1:2024) now in place for bidirectional charging systems.
Major trials are scaling up significantly. The Australian Renewable Energy Agency (ARENA) recently committed an additional $13.6 million to expand Amber Electric’s V2G trial from 50 to 1,000 households, with a focus on BYD vehicles. Origin Energy is also running a V2G trial with 50 customers, offering BYD Atto 3s and StarCharge Halo chargers.
“In May 2026, 46 percent of all new vehicles sold in Australia were either battery-electric, hybrid electric, or plug-in hybrid electric vehicles.”
This rapid EV adoption, with 1 in 5 new vehicles sold in May 2026 being electric, creates significant potential for V2G/V2H. The Tesla Model Y even became Australia’s best-selling car across all fuel types in May 2026.
The Costs of V2G/V2H Chargers & Installation
Upfront costs are a significant consideration. A bidirectional charger in Australia typically ranges from $5,000 to $10,000+, excluding installation.
| Charger Model | Type | Connector | Status (2026) | Estimated Price (AUD, ex-install) |
|---|---|---|---|---|
| Sigenergy SigenStor | DC | CCS2 | Available (V2G via future update) | ~$4,850 (charging module) + inverter costs ($1,800-$5,500) |
| StarCharge Halo V2G | DC | CCS2 | Available, CEC listing pending | ~$6,000 - $10,000 |
| RedEarth Ambibox DC | DC | CCS2 | Deliveries from Feb 2026 | ~$9,990 + GST |
| V2Grid Numbat | DC | CHAdeMO, CCS2 | Approved by Ausgrid (NSW), pricing TBC | ~$10,000+ GST (expected) |
| Wallbox Quasar 2 | DC | CCS2 (older Quasar 1 was CHAdeMO) | Australian release date unknown (expected ~$10,000) |
Installation costs can add $500 to $1,500 or more, especially if switchboard upgrades are needed. This brings the total installed cost for a V2G/V2H system to roughly $6,000 to $12,000.
Compatible EVs in Australia (2026)
While many EVs have the hardware for bidirectional charging, manufacturer software enablement and warranty support are key.
| EV Model | V2L | V2H | V2G | Notes (2026) |
|---|---|---|---|---|
| Nissan Leaf (40/62kWh) | Yes | Yes | Yes | Most established V2G vehicle via CHAdeMO. Used in trials. CHAdeMO is phasing out. |
| Mitsubishi Outlander PHEV | Yes | Yes | Yes | CHAdeMO port. Smaller 13.8kWh battery. Used in SA trials. |
| Kia EV9 Earth AWD | Yes | Yes | Yes | CCS2 bidirectional support confirmed. High battery capacity (99.8kWh). |
| Hyundai IONIQ 5/6/9 | Yes | Yes | Yes | Hardware capable, V2G-enabling firmware rolling out Q3 2026. |
| Kia EV6 / EV5 | Yes | Yes | Yes | Hardware capable, V2G-enabling firmware rolling out Q3 2026 for EV5. EV6 V2G status pending. |
| BYD Atto 3 / Seal / Sealion 7 / Shark 6 | Yes | Yes | Upcoming | Atto 3 successfully trialled V2H/V2G with Ambibox/Sigenergy. BYD has confirmed V2G for future models, and is warranting Atto 3 for Amber trial. |
| Tesla Model 3 / Y | No | Limited | No | Select 2025/2026 builds support limited V2H via specific chargers (e.g., Ambibox). Tesla does not natively offer V2L/V2G. |
| Polestar 2 / Volvo EX30 | Yes | Yes | No | V2H trialled with Ambibox. V2G not confirmed. |
Crucial Note on Warranties: Many manufacturers are still finalising warranty terms for V2G use. Always check with your dealer and charger supplier.
The Benefits: Savings, Resilience & Grid Support
- Lower Electricity Bills (V2H & V2G): The most direct benefit. By charging your EV with cheap off-peak power or surplus rooftop solar, then discharging it to power your home during expensive peak times, you can significantly reduce your grid imports. Early participants in Australian trials have reported net annual benefits of $800–$1,800.
- Solar Self-Consumption: V2H allows you to store excess daytime solar in your EV, using it at night instead of exporting it for low feed-in tariffs (FiTs) or buying expensive peak power. This is currently the dominant use case in trials.
- Time-of-Use Optimisation: Charge when power is cheapest (e.g., overnight on a dedicated EV plan like those discussed in Slash EV Charging Costs by Up To $800/Year: Best Electricity Plans in Australia 2026) and discharge when rates are highest.
- Backup Power During Blackouts (V2H): Your EV’s large battery can power your home for several days during an outage, providing critical resilience. This is a significant advantage over relying solely on the grid.
- Grid Participation & Potential Earnings (V2G): By participating in Virtual Power Plants (VPPs) or demand response programs, your EV can help stabilise the grid during peak demand. In return, you may receive payments or incentives from your energy retailer. This is a growing area, with programs like Amber Electric’s V2G trial actively exploring these benefits.
V2G/V2H vs. Dedicated Home Battery
This is a common question for homeowners. Here’s a comparison:
| Feature | Dedicated Home Battery (e.g., Tesla Powerwall 2) | EV with V2H/V2G Capability |
|---|---|---|
| Capacity (typical) | 10-13.5 kWh usable | 50-100 kWh usable (much larger) |
| Mobility | Fixed installation | Mobile (can be driven away) |
| Primary Function | Home energy storage, solar optimisation, backup | Transport, then supplemental home energy storage/grid support |
| Cost (installed) | ~$10,000 - $18,000 (before rebates) | ~$6,000 - $12,000 (charger + installation, in addition to EV cost) |
| Blackout Backup | Yes, powers home circuits | Yes, powers home circuits for longer durations |
| Grid Export (V2G) | Yes, with compatible inverter & retailer | Yes, with compatible EV, charger, DNSP approval & retailer |
| Flexibility | Always connected, automated | Requires EV to be plugged in at home |
| Battery Degradation | Designed for daily cycling | Manufacturer warranties often cautious about V2G/V2H cycling |
For many, a V2H setup can effectively replace a standalone home battery, especially if you have a large EV battery, solar panels, and a second vehicle or predictable driving patterns. However, the EV must be plugged in to provide power, which is a key difference.

Rebates and Incentives (2026)
While specific V2G/V2H rebates are not yet widespread across all states, general EV rebates and incentives can help offset the initial vehicle cost, making the combined V2G/V2H investment more palatable. These vary significantly by state:
- NSW: No longer offers direct EV rebates on purchase, but stamp duty exemptions for EVs up to $78,000 continue. The state also invests in charging infrastructure.
- Victoria: Ended its $3,000 EV subsidy in June 2024. Stamp duty concessions may still apply for eligible vehicles.
- Queensland: Offers a $3,000 rebate for new EVs under $68,000 (or $6,000 for low-income households).
- South Australia: Offers a $3,000 rebate for new EVs under $68,000. SA Power Networks was the first distributor to allow V2G connections.
- ACT: Continues to offer interest-free loans up to $15,000 for EV purchases, and free stamp duty. Evoenergy (ACT) has approved V2G export.
- Western Australia: Offers a $3,500 rebate for new EVs under $70,000.
These rebates primarily target EV purchase, not specifically the bidirectional charging hardware. However, as V2G trials expand, we may see more targeted incentives emerge.

Is V2G/V2H Worth It for You in 2026?
V2H is a clear winner for many homeowners right now. If you have solar panels and an EV (or are planning to buy one), V2H allows you to maximise your self-consumption, reduce peak electricity purchases, and gain significant blackout resilience. The savings on your energy bill can be substantial, potentially offsetting the charger cost over time.
V2G, while offering greater long-term potential for grid interaction and earnings, is still more complex. It requires specific EV and charger compatibility, network approval, and participation in retail programs. However, with major trials underway and regulatory hurdles largely cleared, V2G is on a strong trajectory for broader commercialisation by late 2026 and into 2027.
Consider V2G if:
- You already own a compatible EV (or plan to purchase one like the Kia EV9, or upcoming Hyundai IONIQ models).
- You have a substantial solar system and want to maximise its value.
- You’re comfortable participating in VPPs and energy trading programs.
- You value grid resilience and wish to contribute to a more stable, renewable energy network.
- The upfront cost of $6,000 to $12,000 for the charger and installation is manageable within your budget.
Prioritise V2H if:
- Your primary goal is to reduce your home electricity bills and achieve energy independence.
- You want reliable backup power during outages without grid complexities.
- You have an EV that supports V2H (many popular models are gaining this capability).
- You want a simpler, more immediate solution without relying on external grid programs.
Bottom Line
For Australians in 2026, investing in V2H technology is a sound decision that delivers tangible benefits through reduced energy bills and enhanced home resilience. With compatible chargers now available (starting from ~$4,850 for the SigenStor charging module) and a growing list of V2H-enabled EVs, the payback for a solar-equipped home is compelling. While V2G offers exciting future possibilities for grid revenue, V2H provides immediate, reliable value by turning your EV into a powerful, on-demand home battery. As the market matures, V2G will layer additional benefits, but V2H is the practical bidirectional upgrade you can implement and benefit from today.
