Bidirectional EV Chargers in Australia: V2G and V2H Are Finally Real
Bidirectional charging turned real in Australia in 2026. What V2G and V2H chargers cost, which cars can do it, and the honest payback maths.

For years, “your EV will power your house” was a promise stuck in trials and paperwork. That changed in 2025-26: the Australian inverter standard now covers bidirectional EV chargers, the first units have reached the Clean Energy Council’s approved list, and you can genuinely order hardware today. The catch is price: roughly $4,850 to over $10,000 for the charger alone as of August 2026, against $750 to $1,650 for a good one-way wallbox. Here’s what exists, what your car needs, and whether the maths works yet.
V2L, V2H, V2G: which is which
V2L (vehicle-to-load) is the simple one: a powerpoint fed by the car, no installation, and it’s been on Hyundai, Kia, BYD and MG models for years; our V2L guide covers it. V2H (vehicle-to-home) feeds your switchboard so the car runs the house, like a home battery on wheels. V2G (vehicle-to-grid) goes a step further and exports to the grid for payment. V2H and V2G both need a bidirectional charger with a built-in inverter, network approval, and a car that plays along, which is why they arrived years after V2L.
The scale is what makes the effort worthwhile: a 60 to 70kWh EV battery holds around five times the energy of a typical home battery, and it’s parked at home most hours of the day.
Is it actually allowed now?
Yes. The pieces fell into place across 2025 and 2026: the amended inverter standard (AS/NZS 4777.2) published, the first bidirectional chargers began appearing on the Clean Energy Council’s approved-products list, and distribution networks started approving connections through the same process used for solar inverters. Retailer programs have begun too, including Origin’s program built around the StarCharge Halo and ACT trials using the Wallbox Quasar 2.
The practical consequence: this is now an installer conversation, not a science experiment. But approval still runs through your local distribution network, and their appetite varies, so “can I connect a V2G charger at my address” is a question your installer must answer before any money changes hands.
What can you buy?
The market is young and moving fast; as of August 2026 the named players are:
| Charger | Power | Indicative price (Aug 2026) |
|---|---|---|
| Sigenergy (SigenStor ecosystem) | up to ~25kW DC | ~$4,850 plus installation |
| StarCharge Halo | 7 to 11kW | ~$6,000; sold through Origin’s program |
| V2Grid Numbat | ~7kW | ~$10,000 plus GST |
| RedEarth / Ambibox | 22kW | ~$9,990 plus GST; deliveries from early 2026 |
| Wallbox Quasar 2 | 11.5kW | Australian release still pending; used in ACT trials |
Treat all of these as indicative: pricing, approval status and availability are changing quarter to quarter, and quotes should come from installers who confirm CEC listing and your network’s connection rules at the time of purchase. More entrants (including Enphase) have flagged Australian bidirectional products, which is the main reason to expect prices to fall.
Which cars can do it?
This is the real bottleneck. Bidirectional charging needs the car’s software to permit it, and manufacturer positions range from enthusiastic to warranty-voiding silence. Australian trials and early deployments have run bidirectional charging with the Nissan Leaf (the CHAdeMO-era veteran), Tesla Model Y, BYD Atto 3, Polestar 2, Volvo EX30 and Mitsubishi Outlander PHEV, and Hyundai has been switching on Ioniq 5 support via updates.
Two warnings before you get excited. First, having V2L does not mean a car can do V2G; they’re different systems. Second, a car working in someone’s trial is not the same as the manufacturer warranting daily bidirectional cycling of your battery. Before buying a $5,000-plus charger, get it in writing that your exact model, year and software version is supported by that charger and blessed by the carmaker.
Do the numbers stack up?
Run the honest version. A household drawing 10kWh across the evening peak at a 30c/kWh-plus rate, supplied instead from an EV charged overnight at around 8c (or from solar surplus at even less), saves roughly $2 to $2.50 a day, call it $700 to $900 a year. Against $5,000 to $10,000 of hardware plus installation, that’s a payback measured in many years, longer than most people keep a car.
The maths gets better fast in specific situations: wholesale-exposed plans that pay serious money for evening exports, big solar systems drowning in unexportable surplus, retailer V2G programs that subsidise the hardware, or genuine blackout-backup value in outage-prone areas. If none of those describe you, the arithmetic today says wait; the standard is settled, the market is arriving, and the second wave of hardware will be cheaper.
Should you wait?
Most people: yes. Charge the car on an overnight tariff or solar with a normal home charger for a tenth of the price, enjoy V2L for free if your car has it, and let early adopters fund the market’s learning curve. Revisit when hardware lands under $3,000 installed or your energy retailer offers a program that carries part of the cost. If you are the early-adopter household (big solar, wholesale plan, supported car, cooperative network), this is the first year the pieces genuinely connect, and the technology is no longer the thing standing in your way.
Frequently asked questions
What is a bidirectional EV charger?
A charger that can move energy both ways: into the car's battery as normal, and back out again to run your home (vehicle-to-home, V2H) or export to the electricity grid (vehicle-to-grid, V2G). It needs an inverter built in, which is why bidirectional units cost several times more than a normal 7kW wallbox.
Is V2G legal in Australia?
Yes, as of 2026 it has moved from trials to reality. The updated inverter standard (AS/NZS 4777.2, amended in 2025) covers bidirectional EV chargers, the first units are appearing on the Clean Energy Council approved list, and network operators are beginning to approve connections the same way they do solar inverters. Approval still varies by distribution network, so your installer must check your local rules.
How much does a bidirectional charger cost in Australia?
As of August 2026, roughly $4,850 to over $10,000 for the hardware alone, before installation. Announced pricing includes Sigenergy's bidirectional unit around $4,850, the StarCharge Halo around $6,000, and premium 22kW units around $10,000. That compares with $750 to $1,650 for a good one-way home charger.
Which cars support V2G in Australia?
It's a moving list, and charger compatibility matters as much as the car. Australian trials have run bidirectional charging on cars including the Nissan Leaf (CHAdeMO), Tesla Model Y, BYD Atto 3, Polestar 2, Volvo EX30 and Mitsubishi Outlander PHEV, and Hyundai has been enabling the Ioniq 5 via updates. Manufacturer warranty positions differ, so confirm both the car and the specific charger are supported before buying anything.
Is a V2G charger worth it yet?
For most households, not quite. Shifting a typical evening's usage from peak rates to stored EV power saves in the order of $700 to $900 a year, which is a long payback on $5,000 to $10,000 of hardware. The maths improves quickly for households on wholesale-exposed plans, with big solar systems, or inside retailer V2G programs, and hardware prices are expected to fall as more units reach the approved list.
