Electric vehicles are no longer just for driving. With V2L and V2H technology in Australia, your EV can now send power back to your home or appliances. But can it fully replace a dedicated home battery? Let’s take a look at how V2L adapters, V2H chargers, and V2G chargers work — and whether the technology is ready for everyday Australians.
What is V2L, V2H, and V2G? A simple breakdown
These three terms all involve your electric vehicle (EV) sharing its stored energy. But they work differently and serve different purposes.
Vehicle-to-Load (V2L) lets you plug appliances directly into your car using a V2L adapter or V2L cable. Think of it like a giant power bank on wheels. You can run a kettle, charge a laptop, or even power a campsite.
Vehicle-to-Home (V2H) is more advanced. A V2H charger connects your EV to your home’s electrical system. Your car can then power lights, appliances, and even air conditioning during a blackout or peak-rate period.
Vehicle-to-Grid (V2G) goes even further. A V2G charger allows your car to export power back to the electricity grid. In Australia, V2G charger trials are underway, but a widespread rollout is still in development.
Powering up your EV with solar
If you’re thinking of buying an EV, adding an EV charger to your solar system is a smart way to “fuel” your car with clean, renewable energy.
How does a V2L adapter work?
A V2L adapter plugs into your car’s charging port and converts DC battery power to AC power. It’s a simple, portable solution for low-demand situations.
Common uses for a V2L adapter include:
- Powering tools on a worksite
- Running appliances during camping trips
- Keeping essentials on during a short blackout
- Charging e-bikes or smaller EVs
The V2L cable is usually included with compatible vehicles or sold separately. Brands like Hyundai, Kia, and Genesis offer built-in V2L capability on several of their EV models in Australia.
A V2L adapter typically provides around 3.6 kW of power output. That’s enough for most household appliances, but not your whole home.
What makes a V2H charger different?
A V2H charger is a bidirectional charger installed at your home. It allows power to flow both ways — into the car to charge it, and out of the car to supply your home.
Unlike a V2L adapter, a V2H charger connects to your home’s switchboard. This means it can power circuits throughout your entire house, not just individual devices.
Key advantages of a V2H charger include:
- Can power your entire home during outages
- Works alongside rooftop solar to maximise self-consumption
- Reduces reliance on the grid during peak pricing periods
- Potentially offsets or replaces the need for a standalone home battery

V2H charger in Australia: What’s available right now?
The V2H charger market in Australia is still in its early stages, but options are emerging. The Nissan LEAF (with CHAdeMO) has been used in V2H setups for years. More recently, the Nissan Ariya and several Japanese domestic-market vehicles have expanded this space.
Here’s a summary of what’s currently shaping up in Australia:
| Feature | V2L Adapter | V2H Charger | V2G Charger |
| Power output | ~3.6 kW | Up to 6–10 kW | Up to 10+ kW |
| Powers the whole home? | No | Yes | Yes |
| Grid export? | No | No | Yes |
| Installation required? | No | Yes (licensed electrician) | Yes (licensed electrician) |
| Cost (approx.) | $300–$700 | $3,000–$8,000+ | $5,000–$12,000+ |
| Australia availability | Wide | Limited but growing | Trials only |
| Compatible EVs (AUS) | Hyundai IONIQ 5/6, Kia EV6, Genesis GV60 | Nissan LEAF (CHAdeMO), select new EVs | Nissan LEAF (trial), future models |
Can a V2H charger replace a home battery?
This is the big question for Australian homeowners. The short answer: it depends on your situation.
A dedicated home battery has a fixed capacity (typically 13.5 kWh). Your EV battery, by comparison, is often 60–100 kWh. That’s a significant advantage in raw storage. Check our page for our recommended solar products.
However, there are some important trade-offs to consider:
- Daily driving needs — If you need your car in the morning, you may not want to leave it drained overnight.
- Battery degradation — Frequent deep cycling for home use could affect your EV battery’s long-term health.
- Charger compatibility — Not all EVs support V2H, and not all V2H chargers are compatible with every car.
- Upfront cost — A quality V2H charger and installation can cost as much as a home battery system.
- Solar integration — V2H systems can integrate with solar, but setup complexity varies.
For some Australians — especially those with large EV batteries, solar panels, and a second vehicle for daily use — a V2H setup could replace a standalone battery. For others, a combined approach may be more practical.
V2G charger in Australia: The future of energy flexibility
A V2G charger takes the concept further by letting your EV export energy to the grid. This turns your car into a revenue-generating asset during high-demand periods.
In Australia, V2G charger trials have been conducted through programs such as the Ausgrid Virtual Power Plant and various state-level energy initiatives. The potential benefits are significant:
- Earn credits or payments for exported energy
- Support grid stability during peak demand
- Reduce household electricity bills further
- Help Australia transition to a cleaner, smarter energy grid
The main barrier to widespread adoption of V2G chargers in Australia is vehicle compatibility. Most EVs sold in Australia today do not yet support V2G. However, this is changing fast as manufacturers prepare next-generation platforms.
Which EVs support V2L and V2H in Australia?
Not every EV on the market supports bidirectional charging. Here’s a quick look at what’s available or coming:
V2L-Capable EVs (available now in Australia):
- Hyundai IONIQ 5 and IONIQ 6
- Kia EV6 and EV9
- Genesis GV60 and GV70
- BYD Atto 3 (limited V2L function)
V2H-Compatible EVs (limited availability):
- Nissan LEAF (CHAdeMO port required)
- Mitsubishi Outlander PHEV (via specific charger setup)
V2G-Ready EVs (emerging):
- Nissan LEAF (trial-ready in Australia)
- Future models from Hyundai, BYD, and Ford (F-150 Lightning — not yet sold in AUS)
As more automakers commit to bidirectional charging standards, the range of compatible vehicles will expand rapidly over the next two to three years.
What to consider before installing a V2H charger in Australia
If you’re thinking about investing in a V2H charger in Australia, here are the key questions to ask:
- Does your current EV support V2H or bidirectional charging?
- Do you have rooftop solar, and how much excess energy do you generate?
- What are your energy usage patterns — do you use most power at night?
- Are you in an area with frequent outages or high grid tariffs?
- What is the total installed cost versus a home battery alternative?
Speaking with a qualified solar and EV specialist will help you assess whether V2H makes financial sense in your specific situation. Energy Matters can connect you with trusted, accredited installers across Australia who specialise in EV charging and solar-integrated energy systems.
The cost comparison: V2H vs home battery in Australia
Costs vary depending on system size, brand, and installation complexity. As a general estimate:
- Home battery: ~$12,000–$16,000 installed
- V2H charger (hardware + installation): ~$5,000–$10,000
- V2L adapter: ~$300–$700 (no installation required)
When you factor in that your EV battery already exists and may store 4–8x more energy than a dedicated home battery, V2H starts to look very competitive. The key is ensuring your EV and charger are compatible and that your usage patterns suit the technology.
Is now the right time to invest?
V2L technology is ready right now — if you own a compatible EV, a V2L adapter or V2L cable is a low-cost, practical purchase. No installation needed.
V2H is ready for early adopters — the technology works, compatible vehicles are available (particularly with CHAdeMO), and installers are gaining experience. Costs are still higher than they’ll likely be in a few years, but the benefits are real.
V2G is on the horizon — the V2G charger Australia ecosystem is building, with trials showing strong results. If you’re buying a new EV today, look for one with future V2G capability, so you’re ready when the market matures.
