V2H and V2G in Australia: Can Your EV Really Power Your Home in 2026?

For years, “your EV can power your house” was a line in a marketing brochure. In 2026, it’s finally real in Australia — but with real caveats.

The standards have caught up. The first bidirectional chargers are Clean Energy Council approved. Energex has a published connection process. And several major retailers and car brands have launched genuine vehicle-to-grid trials in Queensland. If you’re planning or upgrading a home energy system in South East Queensland, bidirectional charging is now worth considering — carefully.

Here’s an honest installer’s view of where it stands.

V2L, V2H, V2G — What’s the Difference?

These three acronyms get thrown around interchangeably. They’re not the same thing.

V2L — Vehicle-to-Load. The car has a built-in AC power outlet (or adapter) that lets you plug appliances in directly. Think camping fridge, power tools, or a kettle during a blackout. Typical output is 2.2–3.6 kW. Useful but limited — you can’t run a whole house from it.

V2H — Vehicle-to-Home. The car discharges through a bidirectional charger back into your home’s switchboard. During a blackout, or during peak tariff periods, your EV becomes a very large battery on wheels. Typical usable capacity: 40–80 kWh, which dwarfs most home batteries.

V2G — Vehicle-to-Grid. Same hardware as V2H, but the energy flows beyond your home and back into the public grid. This requires retailer participation, network approval, and the right tariff — you get paid for the energy you export.

V2L is the easiest to understand and the most widely available today. V2H and V2G need purpose-built bidirectional charging hardware, a vehicle that supports it, and network sign-off.

The Standards Finally Caught Up

The reason V2H and V2G took so long to arrive in Australia is regulatory, not technical.

Until recently, the inverter standard AS/NZS 4777.2 didn’t properly cover bidirectional EV chargers. AS/NZS 4777.2:2020 Amendment 2 was published in August 2024 and came into effect on 23 August 2025 — from that date, the Clean Energy Council only accepts applications compliant with Amendment 2. The new clauses cover Mode 3 and Mode 4 bidirectional EV charging, which gave networks the compliance framework they needed.

As of April 2026, a small but growing number of bidirectional chargers carry CEC approval and can be connected to the grid in Queensland through Energex’s Electrical Partners Portal. A separate future milestone to be aware of: from 1 July 2026, bidirectional chargers will need to meet demand-response requirements (OCPP 2.1 / AS 5438) as part of their connection.

Progress is real. The list of approved products is short.

Which Cars Actually Support It?

Supporting bidirectional charging requires the right hardware and the right software — and the manufacturer has to explicitly enable it. A car can be physically capable and still be locked out by firmware.

CCS2 (the dominant standard in Australia)

• Kia EV6, EV9 — V2L as standard. Kia launched V2H in the US in February 2025 and commercial V2G in the Netherlands in late 2025. In Australia both models are participating in the AGL national V2G trial — a 50-vehicle initial phase across VIC, NSW, QLD and SA, with a commercial V2G proposition targeted for 2026.
• Hyundai Ioniq 5, 6, 9 — V2L as standard. Hyundai Motor Group’s commercial V2G/V2H rollout began in Europe in late 2025. Hyundai is part of the same AGL 50-vehicle Australian trial.
• Polestar 3 — V2H announced in November 2025, launching in California first through a partnership with dcbel. Germany followed via a bidirectional-ready Zaptec Go2 AC charger. No Australian launch date has been confirmed.
• Cupra Born (77 kWh), VW ID. range — V2G hardware is present on the larger-battery European MEB platform cars. Pilots are running in Germany. Australian enablement timing is not confirmed — don’t buy one today assuming V2G will be switched on locally.
• Ford F-150 Lightning — Intelligent Backup Power (V2H) is native in the US with up to 9.6 kW home backup. Not officially sold by Ford Australia; available in small numbers via grey-market importers.
• BYD Atto 3, Seal, Dolphin — V2L via adapter (2.2–3.6 kW). V2H/V2G is not yet a production feature on any BYD sold in Australia. Amber Electric and BYD announced a warranty-backed V2G trial targeting a 2026 launch — worth watching.
• MG4 — V2L (2.2 kW) is standard across the entire range, including the 2026 MG4 Urban.

CHAdeMO (legacy)

• Nissan Leaf — the original V2G vehicle globally, and used in the Australian REVS trial. Existing Leafs work with CHAdeMO bidirectional chargers (Nissan has formally approved the Fermata Energy FE-20 in the US without impacting warranty). Nissan’s next-generation Leaf replacement is expected to move to CCS2 for Australian delivery, aligning the rest of the local market — confirm with your dealer before committing.

Before you buy a car expecting V2H or V2G, confirm the specific model, model year, and firmware with the Australian dealer. Marketing pages often describe future capability that hasn’t been enabled for Australian-delivered cars.

The Charger Side — What’s Actually Available in Australia

This is where the real bottleneck sits. A bidirectional DC charger is a meaningfully more complex piece of hardware than a standard 7 kW AC charger. It inverts DC battery power back to grid-quality AC, synchronises with the grid, and does it safely through thousands of cycles over the car’s life.

As of April 2026, the following products matter for Australian residential installations:

• V2Grid Australia Numbat — Australia’s first CEC-certified standalone bidirectional charger. 7 kW, supports both CCS2 and CHAdeMO, designed and manufactured locally. Targeted at residential.
• Sigenergy SigenStor EV DC Charging Module — a DC-coupled CCS2 bidirectional module (up to 25 kW) that bolts onto a SigenStor all-in-one solar+battery stack and charges/discharges directly across the stack’s DC bus. The effective grid-side export rate is set by the SigenStor inverter’s phase configuration — typically capped at 10 kW on a single-phase home, higher on three-phase. CEC approved, certified to AS/NZS 4777.2 Amd 2. If you’re installing a SigenStor battery anyway, this is the most deeply integrated solar+battery+V2H path on the Australian market.
• Red Earth / Ambibox — 11 kW three-phase bidirectional system, available in Australia. Successfully demonstrated V2H with a BYD Atto 3.
• JET Charge (and Ocular-brand AC products) — Participating in multiple ARENA-funded V2G trials including REVS in the ACT (completed November 2025) and a V2G deployment in South Australia. Commercial residential DC product roadmap for Queensland is still developing.
• Amber Electric’s V2G rollout — Amber has installed the first 50 residential V2G chargers in Australia under a $3.2M ARENA-funded trial and is progressively rolling out commercial V2G bundles tied to its wholesale-price retail plan.

What about Wallbox Quasar 2? Widely reported overseas, the 11.5 kW CCS2 Quasar 2 is being shipped to eligible Kia EV9 owners in the United States. As of early 2026 it is not CEC-approved for Australia and cannot be grid-connected here. Australian availability has not been confirmed by Wallbox.

Installed pricing for a bidirectional charger sits in the $7,000–$15,000 range depending on the unit, your switchboard, and the site. Hardware alone is typically $5,000–$11,000; installation and connection paperwork add another $2,000–$4,000.

Bidirectional chargers now come in both single-phase (typically 7–11 kW) and three-phase (up to 22–25 kW) configurations. Check your switchboard — single-phase homes may be limited to smaller units.

What Does It Actually Save You in SEQ?

Let’s be concrete for South East Queensland.

A typical household in the Energex network uses 13–20 kWh per day depending on size, pool, and air-conditioning load. Queensland flat-rate retail tariffs are sitting around 28–35 c/kWh for the 2025–26 regulated period. Feed-in tariffs have compressed. SEQ (Energex) has no regulated minimum — retailer offers are typically 4–10 c/kWh. Regional QLD (Ergon) has a regulated FiT of 8.66 c/kWh for 2025–26, with a draft determination for 2026–27 signalling a drop to around 6.15 c/kWh from 1 July 2026.

With V2H on a time-of-use arrangement, a reasonably sized EV (60+ kWh usable) effectively becomes the house battery. You charge from solar during the day — free, or near-free — and discharge through the evening peak to avoid 35 c/kWh grid energy. Back-of-envelope: 10 kWh of avoided peak consumption × 30 c/kWh ≈ $3 per day, or roughly $1,000 per year for a typical SEQ household.

With V2G on a dynamic wholesale-linked tariff (Amber being the clearest example), the upside is higher but so is the variance. NEM wholesale spot prices regularly spike above $1/kWh on hot evenings — particularly during summer load events. Amber has publicly indicated an indicative annual V2G value of around $3,000, and early trial customers have reported one-day earnings of $250–$300 on high-price days. Those are headline figures; real-world annual earnings will depend on your car’s availability, how aggressively you let software trade the pack, and market volatility.

Against a $7,000–$15,000 installed cost, payback lands somewhere between 4 and 10 years — before you factor in the EV battery warranty question below.

The Warranty Question Nobody Talks About Enough

This is the part installers don’t always flag clearly, and it matters.

Australian EV battery warranties are typically 8 years / 160,000 km with a 70% capacity-retention threshold (Hyundai, Kia, MG all use this structure; Nissan covers to 9 bars, roughly 66%). Using the car for V2H or V2G puts additional throughput on that battery. How manufacturers treat that varies:

• Nissan has formally approved the Fermata Energy FE-20 bidirectional charger for use with the Leaf in the United States, with confirmation that this doesn’t affect warranty. That’s US-specific — don’t assume it translates automatically to an Australian car.
• BYD + Amber are running a warranty-backed V2G trial in Australia targeting a 2026 commercial launch. Buying into that trial is structurally different from retrofitting a bidirectional charger onto a regular BYD.
• Hyundai and Kia are commercialising V2G through specific retailer/charger partnerships (the AGL national V2G trial is the Australian case). Blanket warranty coverage for any third-party bidirectional charger is not yet standard.
• Most other manufacturers have not published an Australian position on V2H/V2G warranty impact.

Before committing, get your manufacturer’s position in writing for your specific car, in Australia. If you plan to cycle the pack aggressively for V2G revenue, model degradation honestly against the trading income — the battery is the single most expensive component of your car, and accelerating its decline by a year or two can wipe out several years of V2G profit.

For low-intensity V2H — a couple of hours of evening peak shaving, backup during occasional blackouts — additional wear is modest and within most households’ risk tolerance.

Queensland Specifics

A few things that matter locally:

• You’re on the Energex network. SEQ homes connect through Energex (Brisbane, Logan, Ipswich, Moreton Bay, Gold Coast, Sunshine Coast). Regional Queensland is Ergon — different tariffs, different connection process. This post is about Energex.
• Energex has a published V2G connection process. Bidirectional charger applications go through Energex’s Electrical Partners Portal alongside your existing solar and battery. Export limits apply across your total site — your V2G capacity isn’t approved in isolation.
• Static vs Dynamic connections. Residential single-phase is typically capped at a 5 kW static export limit. If you want higher export (up to 10 kW single-phase / 30 kW three-phase), you can apply for a Dynamic Connection. Important caveat: those higher numbers are inverter-capacity ceilings, not guaranteed throughput. Under a Dynamic Connection, Energex can throttle your export in real time — down to as low as 1.5 kW, or occasionally zero, during network stress events. For V2G economics to work, most households will want Dynamic, but model your earnings on a realistic average rather than the ceiling.
• Tariff name matters. In SEQ, the relevant network tariff for a smart-metered household is Residential Time of Use Energy (Energex Network Tariff 6900). Smart-meter properties are now auto-assigned to this tariff. Your retailer’s name for the underlying plan will vary — “Tariff 12A” is a legacy retail code that still appears on some bills but isn’t the current network code.
• Queensland state rebates for EVs and home batteries have closed. The $6,000 QLD EV rebate and the QLD Battery Booster program have both wound up. The active incentive is the federal Cheaper Home Batteries Program (roughly 30% off eligible batteries 5–100 kWh). Important nuances: the battery portion of an integrated system like the SigenStor is eligible; the separate bidirectional EV charging module is not covered by the battery rebate. And the program structure changes on 1 May 2026 — the STC factor drops from 8.4 to 6.8, and rebates become tiered by capacity (100% for the first 14 kWh, 60% for 14–28 kWh, just 15% above 28 kWh). Eligibility is based on installation date, not order date — if you want the current, more generous settings you need the job booked and completed before that cutover.
• CEC-accredited installer required. Any grid-connected V2G install in SEQ needs a licensed electrician, SAA-accredited battery/solar installer, an Electrical Partners Portal connection application, and compliance with AS/NZS 4777.1 and 4777.2:2020 Amd 2. It’s a multi-touch approval path — not a drop-and-go job.

Should You Install One Now, or Wait?

Install now if:

• You already drive (or are about to buy) a confirmed V2H/V2G-capable EV with manufacturer support for the Australian market.
• You’re installing a SigenStor battery system and want the integrated bidirectional module — the incremental cost is lower than retrofitting later.
• You’re on, or willing to move to, a dynamic or time-of-use tariff and you’re comfortable letting software manage charging and discharging.
• Large-home blackout resilience matters to you and you’d rather use the car than add a second battery.

Wait if:

• Your current EV isn’t certified for V2H/V2G in Australia and the manufacturer hasn’t confirmed a local enablement date.
• You’re on a flat tariff and don’t plan to change.
• Your budget is tight — a well-sized solar + home battery combination still delivers most of the economic benefit at lower cost and lower complexity.

For most SEQ households in 2026, the pragmatic path is: install solar now, add a home battery before 1 May 2026 to lock in the current Cheaper Home Batteries Program settings, and pre-wire for a bidirectional charger if the site is going to be rewired anyway. Running the extra conduit and leaving breaker space costs very little today and saves thousands later.

Heads-up if you’re reading this in late April 2026: the Cheaper Home Batteries Program steps down on 1 May 2026 — STC factor drops from 8.4 to 6.8, and rebates are tiered (100% for the first 14 kWh, 60% between 14–28 kWh, 15% above). The rebate is assessed on installation date, not order date. For a typical 10–20 kWh SigenStor or equivalent battery, that’s often several thousand dollars of difference. If you’re already leaning toward a battery install, the clock is measured in days, not months — talk to your installer now.

What We’re Quoting Today

In practice, the bidirectional jobs High Energy is being asked to quote in early 2026 fall into three buckets:

1. SigenStor + DC module bundles — customers committing to a premium all-in-one battery who want the V2H capability included. This is the cleanest path we see today.
2. Numbat standalone installs — for customers with an existing solar/battery system who want to add bidirectional charging without replacing other hardware.
3. Future-proof pre-wiring — customers who don’t want a bidirectional charger yet but want the conduit, breaker space, and metering done now so the upgrade is a half-day job later, not a full rewire.

We’re not yet installing them in volume — the market is still early — but quote enquiries have roughly tripled over the last six months. That trend is real.

The Bottom Line

V2H and V2G are no longer science projects in Australia. They’re working, installable, approvable under Energex’s connection process, and — for the right household — they can meaningfully lower energy costs and add serious blackout resilience.

They’re not yet mainstream, and the cost/benefit is narrow enough that getting the setup wrong — wrong car, wrong tariff, wrong charger, wrong expectations — wipes out the benefit. This is a category where choosing an installer who understands both the electrical side and the energy-market side matters more than usual.

If you’re considering it, the first question isn’t “which charger?” It’s “what’s my car, what’s my tariff, and what am I actually trying to achieve?” Get those right and the hardware decision becomes much simpler.
