What the Wallbox Quasar 2 actually does
The Quasar 2 is a DC bidirectional charger. That distinction matters. Standard home chargers supply alternating current to your car and let its onboard converter handle the step down to DC for the battery. The Quasar 2 bypasses that. It talks directly to your vehicle’s high-voltage battery pack via CCS2, charging at up to 12 kW and discharging at up to 12.48 kW, with 11.5 kW rated output even at 50°C ambient, per Wallbox’s North American technical datasheet.
Because it bypasses the car’s onboard charger, it can pull energy back out of the battery at meaningful speeds. That is what makes V2H (powering your home from your car) and V2G (selling energy back to the grid) possible.
This is different from V2L, the socket in the boot of a BYD Atto 3 or Kia EV6 that can run a kettle or charge a laptop. V2L taps the battery through a standard AC socket and is limited to around 2 to 3 kW. The Quasar 2 can transfer over 11 kW in and out of your home’s wiring, more than a typical electric shower draws at full power.
Wallbox also notes that drawing power at a consistent, steady rate is far less demanding of your EV battery than the frequent high-power demands of accelerating and braking.
Is the Wallbox Quasar 2 actually on sale in the UK in 2026?
Not quite. As of June 2026, the Wallbox UK product page presents a register-your-interest sign-up rather than a checkout, and no UK retail date has been confirmed.
The broader context: Wallbox has started the rollout elsewhere. In North America, pre-orders opened for Kia EV9 owners under Wallbox’s partnership with Kia, and Wallbox has announced its first Quasar 2 V2H installations in California.
For a UK buyer today, you can register your interest, speak to specialist installers, and plan your install. You cannot yet place a confirmed delivery order.
How much will it cost?
Wallbox has not published a final UK retail price. Based on European pricing reported at launch, the unit is widely cited at around £6,100 before installation. Treat that figure as an estimate until Wallbox publishes UK pricing.
That is not the total cost. The Quasar 2 requires a specialist installer, a DNO G99 application (necessary because the charger can export to the grid, and approval can take several weeks), and grid isolation hardware so your home can run from the car safely. You may also need a G100 export cap review depending on your local grid constraints. Installation quotes will run well beyond a standard home charger fitting; get itemised quotes before committing.
Wallbox states that owners can “save up to £850 annually.” That is a vendor claim based on specific time-of-use tariff assumptions, excluding grid fees, taxes and levies; treat it as an upper bound. Octopus Power Pack, the UK’s only mass-market V2G tariff, cites savings of approximately £620 per year for a 7,500-mile-a-year driver against a standard variable tariff, but that figure is built on Quasar 1 hardware. Set those annual savings against a five-figure-adjacent total outlay and the simple payback period runs well past a decade, assuming savings begin from day one. For most households, the financial case alone does not yet stack up. The Quasar 2 is a long-term technology bet, not a five-year return-on-investment purchase.
Which cars actually work with it?
Every CCS2-compatible EV can charge from the Quasar 2. The list of cars that can use V2H or V2G is much shorter.
Bidirectional operation requires the vehicle to support DC bidirectional communication via its CCS2 port, and Wallbox confirms that bidirectional functionality is only permitted with certain makes and models. Confirmed compatible vehicles include:
- Kia EV9, confirmed through Wallbox’s partnership with Kia, which underpinned the North American launch
- Cupra Born 77 kWh, confirmed by Wallbox as the first European EV with Quasar 2 bidirectional compatibility
Some sources suggest the Hyundai Ioniq 5 and Ioniq 6 may follow, but Wallbox has not confirmed this for the Quasar 2.
Popular UK EVs including the VW ID.3, VW ID.4, Polestar 2, Tesla Model 3, Tesla Model Y, Renault Megane E-Tech, and BMW iX are not currently compatible with the Quasar 2 for bidirectional operation.
For a full list of bidirectional-capable vehicles available in the UK, see our V2H Compatible Cars 2026 guide.
Does the Wallbox Quasar 2 work with Octopus Power Pack?
Not yet. This is the most commercially significant question for UK buyers, and the current answer is no.
Octopus Power Pack is the UK’s first mass-market V2G tariff. It manages your car’s charging and discharging automatically, buying cheap electricity overnight and selling energy back at peak times. For a driver covering 7,500 miles a year, Octopus estimates savings of approximately £620 annually versus a standard variable tariff.
Power Pack currently works with the Wallbox Quasar 1, the older CHAdeMO-socket unit, paired with the Nissan Leaf, Nissan e-NV200 or Mitsubishi Outlander PHEV. Octopus has said it is working on more integrations, but the Quasar 2 is not on the current approved hardware list as of June 2026.
Until the Quasar 2 is added to Power Pack, UK buyers cannot access the V2G export income that underpins much of the product’s financial case. If you want V2G income from Octopus today, the Quasar 1 remains the only confirmed UK route.

Installation: what a UK fitter actually has to do
A standard Pulsar Max or Andersen A3 installation takes a qualified charge point installer about half a day. The Quasar 2 is a different project entirely.
A UK install involves:
- Specialist installer: Wallbox’s installation network or a certified third-party installer is required; this is not a task for a standard EV charger fitter
- DNO G99 application: required because the charger can export to the grid; approval can take several weeks, and your installer should handle it, but factor the wait into your planning
- Grid isolation hardware: needed so blackout mode can safely island your home from the grid during an outage; in North America Wallbox pairs the Quasar 2 with its Power Recovery Unit, and the equivalent UK hardware requirement should be confirmed with your installer as separate kit at additional cost
- Potential G100 export cap: some DNOs apply a low default export limit; a G99 application lets you request a higher allowance, but approval is not guaranteed
None of this is impossible. But the Quasar 2 install is a multi-week project with specialist compliance requirements, not a same-week fitting job. Budget for both the lead time and the additional hardware costs before committing.
What about solar?
The Quasar 2 is compatible with solar charging, letting homeowners use rooftop solar energy for both vehicle and home use, and taking DC power into the battery without the conversion losses that AC-coupled charging incurs.
In practical UK terms, the summer yield from a typical 4 kW domestic array can contribute meaningfully to daytime EV charging, particularly for shorter commuter journeys. The Wallbox app can prioritise solar charging when PV generation exceeds home demand.
For most UK households, solar integration is a useful feature rather than a headline reason to buy. Solar generation alone will not power a significant V2H discharge cycle; it is better understood as a way to reduce your EV’s running cost rather than a standalone energy-independence solution.
Quasar 2 vs Quasar 1: which one do you actually want?
These two chargers serve different buyers.
Wallbox Quasar 1 (CHAdeMO): Available now. Supported by Octopus Power Pack. Cheaper. Works with CHAdeMO vehicles such as the Nissan Leaf. If you have a Leaf, want V2G income from Octopus today, and can meet the install requirements, this is the more practical choice in 2026.
Wallbox Quasar 2 (CCS2): Not yet at UK retail. Not yet on Power Pack. More expensive. But it uses the connector that current and future bidirectional EVs in Europe will use, and it is the right long-term platform if your next car supports CCS bidirectional charging.
If you are buying a new EV from a manufacturer actively adding CCS bidirectional support, such as Kia or Cupra, the Quasar 2 is the more future-proof investment. If you need V2G working and earning today, the Quasar 1 with a compatible Leaf is the more straightforward path.
Frequently Asked Questions
Is the Wallbox Quasar 2 available in the UK? As of June 2026, no. The Wallbox UK product page offers a register-your-interest sign-up rather than a checkout, and a firm UK retail date has not been confirmed. Wallbox has begun deliveries in North America under its Kia EV9 partnership.
How much does the Wallbox Quasar 2 cost in the UK? A UK retail price has not been published. Based on European pricing reported at launch, the unit is widely cited at approximately £6,100 before installation. A specialist install, including the DNO G99 application and grid isolation hardware, adds significantly to that; get itemised quotes rather than relying on estimates.
Which cars work with the Wallbox Quasar 2 for V2H or V2G? All CCS2 EVs can charge from the Quasar 2. Bidirectional V2H and V2G functionality is confirmed by Wallbox on the Kia EV9 and Cupra Born 77 kWh. Most mainstream UK EVs, including the VW ID range, Tesla, Polestar and Renault, cannot currently use V2H or V2G with this hardware.
Does the Wallbox Quasar 2 work with Octopus Power Pack? Not as of June 2026. Octopus Power Pack, the UK’s only mass-market V2G tariff, currently supports the older Wallbox Quasar 1. Octopus has said it is working on more integrations, but the Quasar 2 is not yet on the approved list.
How long is the Wallbox Quasar 2 warranty? Two years, per Wallbox’s North American technical datasheet. UK warranty terms have not been separately confirmed; verify with your installer before purchase. Note that UK consumer law provides separate statutory rights against the seller under the Consumer Rights Act 2015.
Is the Wallbox Quasar 2 worth it? For most UK buyers in 2026, not yet. The product is not at retail, Octopus Power Pack does not support it, and compatible vehicles remain a short list. Early adopters with a Kia EV9 or Cupra Born, off-street parking, and a 10-year planning horizon are the right audience now.
