The short version
An electric car carries a battery roughly five to ten times the size of a typical home battery. The obvious idea — park it in the driveway and let the house, or the grid, draw on it — has been technically possible for a decade and practically impossible in Australia for almost as long, because there was no standard that let a car’s battery export through an inverter to the grid.
That changed with AS/NZS 4777.2:2020 Amendment 2:2024, which added clauses covering electric vehicle supply equipment and opened the door to bidirectional charging. The Clean Energy Council and distributors flagged a transition period, with the amended standard taking effect on 23 August 2025. Since then the pieces have arrived in order: the first standalone bidirectional charger onto the CEC approved inverter list, then network approvals, then real customers.
Two years ago V2G here was a trial you applied to join. In July 2026 it is a product you can buy, on two conditions: your distributor allows it, and your car is on a very short list.
Sorting out V2L, V2H and V2G — they are not the same purchase
The three terms get used interchangeably in marketing and they should not be.
| V2L (vehicle-to-load) | A power point on the car. Plug in a kettle, a power tool or a camp fridge. No electrician, no approval, no grid involvement. Many EVs sold here already do it — including models that do nothing else on this list. |
|---|---|
| V2H (vehicle-to-home) | The car powers the house through a bidirectional charger and a switchboard, usually with backup capability during an outage. Needs an approved device, a licensed installer and, in practice, distributor sign-off. |
| V2G (vehicle-to-grid) | Everything V2H does, plus exporting to the grid so you can sell energy at peak prices. This is the one that needs a formal connection application, a standards-compliant inverter and a retailer that will actually pay you for the export. |
Most of the money in the 2026 story is on the V2G line, because a home battery can only ever shave your own bill, while a car exporting into a wholesale-linked tariff can earn during price spikes. But most of the certainty is on the V2L line. Be clear which one a salesperson is quoting you.
Where you can actually connect one
V2G is a distribution-network question before it is a shopping question. Two networks stand out in mid-2026.
SA Power Networks describes itself as the first electricity distributor in Australia to allow network connection of V2G chargers outside trial conditions. Its rules are worth reading closely because they are the most explicit published anywhere here:
- The charger’s inverter must be on the Clean Energy Council approved inverters list.
- In South Australia it must also be on the Office of the Technical Regulator’s approved devices list. SA Power Networks states that V2G chargers must comply from 1 July 2026, including OCPP 2.1 and AS 5438 requirements.
- A V2G inverter is treated as a battery energy storage system for capacity purposes. For sites with 30kVA or less of generation, combined V2G plus home-battery capacity is capped at 10kVA per phase — inverters can be generation-limited to fit.
That last point catches people out. If you already have a home battery, a V2G charger does not sit outside your allowance; it competes with it.
Ausgrid, covering Sydney, the Central Coast and the Hunter, takes connection applications for CEC-approved bidirectional chargers through its normal process. Its published requirements are that the charger complies with AS/NZS 4777.2 and appears on the CEC approved inverter list, or has written equipment approval from Ausgrid; a connection application must be lodged for each premises. Ausgrid also invites distributors of chargers that are not yet CEC-listed but hold an AS/NZS 4777.2:2020 Amd 2:2024 suitability certificate to apply for approval directly.
Elsewhere it is patchier. Trials and case-by-case approvals exist in other network areas — Hyundai has been testing vehicles and third-party bidirectional hardware at Essential Energy facilities in Port Macquarie — but a blanket “yes, apply” is not yet the national position. Check your own distributor first; it is the cheapest step in the whole process.
The hardware, and the money
The first standalone bidirectional charger to clear CEC certification in Australia was the V2Grid Numbat, which also secured Ausgrid network approval. Others reported as available or approaching approval include the StarCharge Halo, Infypower’s Numbat7 and SigEnergy’s integrated system. It is a handful of devices, not a market.
Prices reported by Australian industry guides in 2026 cluster around $7,000 to $15,000 for the hardware, and $12,000 to $20,000 installed once you add the electrician, any switchboard work and, for backup capability, a changeover arrangement. Treat those as a range to budget against and get written quotes; installed cost varies enormously with what your board looks like.
Against that, the reported returns. Amber Electric, which runs the largest residential V2G programme in the country, has published case-study numbers from its trial: a Victorian customer with a 6.6kW solar system and no home battery earned roughly $150 to $200 in a single high-price event in June 2025, and more than $250 during another spike later the same month, when wholesale prices touched $16.60/kWh and briefly exceeded $20/kWh. In May 2026 reporting on the trial’s expansion put potential savings at up to about $2,500 a year, and cited a South Australian customer who earned around $500 in a single day during an Australia Day heatwave.
Those are real numbers from real customers, and they are also the good days. A $500 day is a wholesale price event, not a Tuesday. The honest arithmetic on a $15,000 installed system earning $1,000 to $2,500 a year is a payback measured in years, heavily dependent on staying on a wholesale-linked tariff and on price volatility continuing. Anyone quoting you a two-year payback is quoting you a heatwave.
The trial that is doing the heavy lifting
Most of what Australia knows about residential V2G at scale comes from one project. On 29 May 2026 ARENA announced an additional $13.6 million for Amber’s EV charging project, taking total ARENA funding to $16.8 million and expanding it from 50 to 1,000 households with V2G capability, alongside a smart-charging cohort growing from 950 to 2,000 households. BYD is a project partner supplying vehicles.
ARENA chief executive Darren Miller framed the point of the exercise as system-level rather than personal: the project “brings those pieces together to demonstrate how EVs can become an active part of the energy system,” meaning “savings for owners and better utilisation of the grid, which can bring down the cost of the network for everyone.” Reporting on the expansion noted the original trial drew more than 6,000 enquiries — demand is not the constraint.
What the trial has surfaced is more useful than the headline. Amber’s own write-up on lessons learned lists the actual blockers: only a handful of V2G chargers available in Australia, certification bottlenecks for network connection, network approval that varies by location, and most vehicle manufacturers lacking formal V2G support and warranty clarity. Every one of those is a supply-side problem, not a demand-side one.
Which cars — and the warranty question nobody wants to answer
This is where enthusiasm meets the spec sheet. Australia’s DC fast-charging standard is CCS2, and DC bidirectional charging uses the same plug, but the car’s own software has to permit export. Broad picture in mid-2026:
- Nissan Leaf — the original V2G car globally, working over CHAdeMO, with Nissan having formally approved certain chargers. The catch is that CHAdeMO is a dead end here; the Leaf’s successor is expected on CCS2.
- Hyundai Ioniq 5, Kia EV6 and EV9 — the CCS2 models most often cited as bidirectional-capable, with the caveat that capability depends on build date and firmware version.
- BYD — supplying vehicles into the Amber trial under a warranty-backed arrangement, but most BYD models sold retail here today do V2L only and cannot export to home or grid.
- Tesla — not a participant in retail V2G in Australia as of writing.
The warranty issue deserves its own paragraph because a carmaker put it on the record. In March 2026 Hyundai’s senior manager of future mobility and government relations, Scott Nargar, told The Driven that some V2G chargers available in Australia “achieve bi-directional charging operation by bypassing OEM software and hardware, which is not recommended due to potential safety risk.” The specific concerns raised were that manufacturer warranties and building insurance may not cover damage from non-approved equipment, that a vehicle could discharge without the driver’s knowledge, that a pack discharged to absolute zero could be damaged beyond repair, and that there is a thermal risk if a pack has not been properly inspected after accident repair.
You do not have to read that as a reason never to buy V2G. Read it as the reason to insist on one thing in writing before you do: that your car brand supports export through the specific charger you are installing, and that doing so does not affect your battery warranty. If the answer is vague, the risk is yours, not the installer’s.
Who this is actually for in 2026
| Owner of an Ioniq 5, EV6 or EV9 in an Ausgrid or SA Power Networks area, on a wholesale tariff | The one genuinely well-served case. The network will take your application, hardware exists, and the tariff is what turns the export into money. Get the warranty position in writing first. |
|---|---|
| Anyone choosing between V2G and a home battery | Home batteries are cheaper, simpler, always plugged in and covered by the federal battery rebate. V2G wins on capacity and on peak-price earning; it loses whenever the car is not home. In South Australia the two also share one 10kVA-per-phase allowance. |
| Buyers outside Ausgrid or SAPN | Ask your distributor before you shop. Approval, not hardware, is the binding constraint in most of the country right now. |
| Everyone who just wants backup power in an outage | V2H, or a home battery, is the cheaper and less complicated answer. You do not need grid export to keep the fridge running. |
| Buyers whose car does V2L only | Nothing to do here yet, and no firmware update is guaranteed. Do not buy a car today on the promise of V2G tomorrow. |
The bottom line
V2G in Australia crossed a real line in the past twelve months. The standard exists and is in force, chargers are certified, two significant distributors take applications from ordinary customers, and a thousand-household programme is being funded to prove the economics at scale. That is a genuine shift from “interesting overseas” to “installable here.”
What has not shifted is the cost curve or the car list. At $12,000 to $20,000 installed, with a handful of approved devices and a small set of eligible vehicles, this is early-adopter territory — worth it if you already own the right car, live in the right network area and are on a tariff that rewards exporting at the worst possible moment for everyone else. For most Australian EV owners in 2026 the sensible move is to keep an eye on it, buy the car you want on its own merits, and revisit when the approved-charger list runs to more than a handful of names. The direction of travel is clear. The value is not yet universal.
