The battery in a modern electric vehicle holds much more energy than most home battery storage systems. V2X vehicle-to-home technology lets you put that energy to work beyond driving, by powering your home directly from your car. V2X is short for vehicle-to-everything, and vehicle-to-home is one part of it. You can also sell stored energy back to the grid, or run appliances directly from your EV on a job site or campsite.
The technology is real. The hardware exists. Trials are already underway in Australia. But for Perth homeowners, the real picture is more complex than the headlines suggest. This guide covers what is available now, what is genuinely coming, and the real-world caveats. Understanding these will help you make smarter decisions about your solar, battery, and EV setup today.
What V2X Actually Means
V2X is an umbrella term. It covers three different capabilities. Each one needs different hardware, faces different regulatory hurdles, and suits different practical uses.
V2H — Vehicle to Home
Your EV discharges power to your home. This can happen during a blackout, during a peak demand period, or simply in the evening when your solar is not generating. The car’s battery supplies electricity to your household loads. Think of it as a very large home battery on wheels, one that also takes you to work.
V2H does not need a grid connection or network approval. It operates entirely within your property. This makes it simpler to set up, from a regulatory standpoint, than V2G.
V2G — Vehicle to Grid
Your EV discharges power to the electricity grid. This earns you a credit or payment for the energy you export. V2G is the most commercially interesting capability, and also the most complex. It needs a bidirectional grid connection, network approval, a compatible tariff arrangement, and an aggregator or retailer to manage the dispatch. The current Australian trials focus on V2G, not V2H.
V2L — Vehicle to Load
V2L uses power outlets built into the EV itself. These let you plug in appliances directly from the car, without any home infrastructure. This capability is already active on a number of vehicles sold in Australia today, including several Hyundai, Kia, BYD, and Ford models. It needs no special charger and no network approval. V2L is the one form of V2X that Perth households can genuinely use right now.
Where V2X Is At in Australia Right Now
The most significant V2X development in Australia is the Amber Electric vehicle-to-grid trial. The Australian Renewable Energy Agency (ARENA) funds it. It started as a 50-household pilot. ARENA has since added $13.6 million in funding, bringing total government support to $16.8 million. The trial is now expanding to 1,000 participating households.
The trial is a genuine milestone. BYD has confirmed warranty coverage for participating vehicles. This addresses the single biggest concern that has held back wider V2G adoption. Early financial results have been striking. Some households have earned hundreds of dollars in a single day, or in one overnight session, by exporting from their EV during peak demand events.
The trial spans the ACT, New South Wales, Queensland, South Australia, and Victoria. Western Australia is not included.
When Can Perth Expect V2X?
This is where honesty matters more than enthusiasm. The short answer is: not soon. The reasons are structural.
Western Australia’s energy market is fundamentally different from the east coast states. Synergy, Western Power, and the Economic Regulation Authority are all state-owned. The WA electricity market is non-contestable. There is no competitive retail sector, no private grid operator, and no independent aggregators competing to offer V2G products the way Amber Electric does in NSW and Victoria.
In the NEM states, competition drives market innovation. Private retailers, energy aggregators, and grid operators have a commercial incentive to develop and launch new products quickly. In WA, regulatory change needs government and state-owned entities to align. This process is typically more deliberate, more conservative, and much slower.
Technologies like V2G need new tariff structures, network agreements, metering arrangements, and grid operator protocols. In WA’s non-contestable environment, that regulatory and commercial development takes longer by default. Perth households who are excited about V2G should understand this: even as the east coast moves toward commercial availability, WA is likely to be several years behind.
V2H operates off-grid within the property, so it depends less on regulation. It could be available to Perth households sooner. But it still needs compatible hardware and a vehicle that supports bidirectional discharge. Those constraints are significant today.
Western Power, WA’s distribution network operator, does have a dedicated EV-to-grid connection page. It is actively fielding enquiries from suppliers about V2G. Western Power advises customers to stay in contact with their supplier. Customers should also confirm that equipment is registered with the Clean Energy Council and compliant with Western Power’s network requirements. This is a positive sign that the groundwork is being laid. But registration, compliance, and network approval frameworks still need to mature before V2G is practically available in WA.
The EV Warranty Caveat
This consideration rarely makes it into V2X marketing material. But it is one of the most important things to understand before planning around V2H or V2G.
Every time your EV discharges to power your home or the grid, the battery cycles. In battery terms, those cycles are equivalent to driving. They add throughput, they contribute to degradation, and in most EV warranties, they count toward the limits that decide your coverage.
EV batteries are warranted on a mix of time and either kilometres driven or total kWh throughput. If you discharge your vehicle battery to cover household loads every evening, this adds extra cycles on top of normal driving use. You may use up your warranty allowance much faster than a driver who only uses the car for transport. A vehicle that would otherwise sit comfortably within warranty at year eight could reach its throughput limit by year five, if it has also been powering the house.
The warranty position varies a lot by manufacturer. BYD is currently the standout. The Amber Electric trial is specifically warranty-backed by BYD, meaning V2G discharge does not void the battery warranty for participating vehicles. This is a deliberate and meaningful commitment. Most other manufacturers have not made a similar commitment. For many vehicles on Australian roads today, bidirectional discharge is not covered under the standard battery warranty, even where the hardware technically supports it.
Before you plan any V2H or V2G setup around a specific vehicle, confirm the warranty position for that make and model with the manufacturer. This is not a small consideration. An EV battery is a $20,000 to $40,000+ component, and the consequences of operating outside warranty terms can be significant.
Home Batteries vs Your EV: The Right Tool for Each Job
For covering household loads, a dedicated home battery is still the better solution. This is likely to stay true even as V2X becomes more accessible.
A home battery is designed specifically for daily cycling. Its warranty is calculated around that use case. It stays permanently connected to your solar and inverter system. It charges and discharges automatically, based on your generation, your loads, and your tariff. It does not depend on whether your car is at home, plugged in, or charged enough. And it does not add cycles to a vehicle battery that has its own warranty obligations.
V2X, particularly V2H, has genuine appeal as a backup or emergency capability. An EV battery is a large reservoir of energy. In an extended grid outage, it could provide meaningful backup beyond what a home battery alone could offer. But as your main daily energy management tool, it brings complications that a dedicated home battery does not: vehicle availability, warranty implications, and charging round-trips.
Our recommendation: invest in a well-sized home battery system as the foundation of your energy setup. If V2X becomes available, and your vehicle supports it with warranty coverage, it can add to your home battery rather than replace it.
Which EVs Support Bidirectional Charging in Australia?
The honest picture: very few vehicles currently available in Australia have activated bidirectional capability. This is despite most modern EVs having the underlying hardware to support it.
- Nissan Leaf (older models, CHAdeMO): One of the earliest V2H-capable vehicles in the world. It uses the CHAdeMO charging standard. Australia is phasing out CHAdeMO in favour of CCS2, which limits its future relevance.
- CUPRA Born: Supports V2H through a compatible bidirectional AC charger. It is one of the few CCS2 vehicles with active V2H capability in Australia.
- BYD models: BYD is furthest ahead on bidirectional technology in Australia, especially given its warranty coverage commitment through the Amber Electric trial. Strong hardware support and manufacturer backing make BYD the standout option for V2G participation as the technology develops.
- Mitsubishi Outlander PHEV: Supports bidirectional charging through compatible chargers. It is a plug-in hybrid rather than a full EV, with a smaller battery, but it is an established V2H option.
Most EVs currently sold in Australia, including many Hyundai, Kia, Tesla, and other popular models, have hardware that could in theory support bidirectional charging. But the manufacturer has not activated that capability. Software updates, warranty commitments, and regulatory framework development are all needed before most of these vehicles are practically usable for V2H or V2G.
Positive Energy Solutions and Bidirectional-Ready Hardware
Positive Energy Solutions currently supplies and installs two chargers with bidirectional capability built into the hardware:
SigEnergy Bidirectional DC Charger
The SigEnergy DC charger is among the fastest home-capable DC chargers available in Australia, at 25kW. It is built with bidirectional V2X hardware as part of the SigenStor integrated energy system. Its DC architecture charges and discharges through direct current, rather than converting to AC. This matters for V2X because it allows more efficient energy transfer between the EV battery and the home energy system.
SigEnergy’s bidirectional capability is not yet activated in Australia. It is waiting on vehicle compatibility standards and regulatory frameworks. But the hardware foundation is already in place. Customers who install the SigenStor with the DC charger today are positioned to access bidirectional functionality as those standards develop, and as more vehicles with compatible support arrive.
Fronius Wattpilot Flex
The Fronius Wattpilot Flex is hardware-ready for bidirectional charging through ISO 15118. This is the international standard that enables Plug and Charge and bidirectional V2X communication between the vehicle and the charger. Like the SigEnergy DC charger, the Fronius Flex currently operates in AC charging mode, while the regulatory and vehicle compatibility landscape for V2X develops in Australia.
Fronius has been active in contributing to bidirectional charging standards in Australia. It is well-positioned to activate V2X capability as the framework allows. Customers installing a Fronius Wattpilot Flex today are investing in hardware that is ready for that transition.
For Perth households, both chargers are a forward-looking choice. They are solid, capable EV chargers today, with the hardware foundation to support V2X when the regulatory and vehicle ecosystem in WA is ready.
The Bottom Line for Perth Households
V2X is a genuinely exciting technology, and the direction of travel is clear. But for Perth homeowners making decisions today, here is the practical picture. V2G is not available in WA, and is unlikely to be for some time. V2H is possible in limited circumstances, but it comes with EV warranty implications that you must take seriously. V2L is available now on compatible vehicles.
The best foundation for a Perth home energy setup is still solar, a well-sized home battery, and, if you are ready, an EV charger. Want to be ready for V2X once it becomes viable in WA? Choose bidirectional-ready hardware, like the SigEnergy DC charger or Fronius Wattpilot Flex, and a vehicle from a manufacturer with a clear warranty position on bidirectional use. Those are the smart moves to make now.
Positive Energy Solutions can help you design a system that is optimised for today and ready for what is coming.

Frequently Asked Questions
Can I do V2H right now in Perth?
V2L, powering appliances directly from your EV through built-in outlets, is available now on compatible vehicles. It needs no special installation. True V2H means your EV discharges through a bidirectional charger to power your home. This needs a compatible vehicle with active bidirectional support, a bidirectional charger, and in most cases manufacturer warranty confirmation. The hardware is available, but the vehicle compatibility and warranty picture is limited for most models currently on Australian roads.
What happens to my EV warranty if I use V2H?
This depends entirely on your vehicle manufacturer’s warranty terms. For most EVs currently sold in Australia, bidirectional discharge is not explicitly covered, and it could affect your battery warranty. BYD is currently the standout exception. It has confirmed warranty coverage for V2G discharge for participants in the Amber Electric trial. Always check with your manufacturer before using your vehicle for V2H or V2G. The battery is a high-value component, and the warranty implications are significant.
Is V2X a replacement for a home battery?
No, at least not for most Perth households at this stage, and arguably not even as the technology matures. A home battery is designed and warranted for daily energy cycling. It is permanently available, automatically managed, and does not depend on vehicle availability. It also does not add warranty risk to another high-value asset. V2X can add to a home battery, particularly for extended backup scenarios, but a dedicated home battery remains the better foundation for daily solar energy management.
Do I need a special EV for V2X?
Yes. Bidirectional charging needs a vehicle that supports it. Specifically, it needs an onboard charger that can discharge DC power back through the charge port. Most EVs currently available in Australia have the hardware capability, but the manufacturer has not activated bidirectional mode. Check with your vehicle manufacturer for the current position on your specific model.
When will V2G be available in WA?
There is no confirmed timeline. The Amber Electric V2G trial currently operates across the ACT, NSW, QLD, SA, and Victoria. WA is not included. Western Australia’s energy market is non-contestable, with state-owned retailers, a single grid operator, and one regulator. This means the competitive market innovation driving V2G development on the east coast does not apply here in the same way. WA households should expect to be behind the east coast states by a meaningful margin when V2G does eventually arrive.
