Indra Smart PRO vs Wallbox Quasar 2

> V2G boundary: A “V2G-ready” label or ISO 15118 support does not by itself provide bidirectional power conversion, export approval or a live energy service. Confirm the compatible car, genuinely bidirectional hardware, certified complete system, installer, service and network approval before assigning value to the claim. Read the UK V2G explainer.

A £5,705 gap — and it isn't close to an apples-to-apples comparison

These are not competing products. The Indra Smart PRO is a £395 AC home charger that puts electrons into your car. The Wallbox Quasar 2 is a £6,100 bidirectional DC unit that — in theory — puts electrons into your car and sends them back to your house or the grid. One is a commodity you can have fitted next week. The other is a pre-registration page and a vision of the future.

• Indra Smart PRO — £395, 7.4 kW AC, OZEV-approved, includes surge protection and CT clamp. A straightforward smart charger with a low effective cost.
• Wallbox Quasar 2 — £6,100, up to 12.8 kW bidirectional DC, CCS2, not OZEV-approved, UK pre-registration only. The reference V2H/V2G product for early adopters.

The £5,705 between them buys a technology class change, not a feature upgrade. Most readers should stop here and buy the Indra.

What the Indra Smart PRO actually costs on the wall

The sticker says £395. The box includes a surge protection device — typically £100–£150 off the electrician's bill — and a CT clamp for solar diversion, which would otherwise add another £50–£100. Factor those in and the effective unit cost lands somewhere around £150–£250 before you touch the install itself. For eligible renters and flat owners, the £500 OZEV grant covers the unit outright and chips into the install costs too.

Installation runs £400–£600 for a standard single-phase fit. Smart tariff scheduling works with Octopus Intelligent Go, Octopus Go, OVO Charge Anytime, and EDF GoElectric. The app is basic compared to the Ohme Home Pro or Hypervolt Home 3 Pro, and the installer network is smaller. But at this price, with those included accessories, it is hard to argue with the maths. If you want a deeper look at how it stacks up against the mainstream field, the Ohme Home Pro vs Indra Smart PRO comparison is the more useful matchup for most buyers.

What the Quasar 2 promises — and what it demands

The Quasar 2 is the most ambitious home charger on the UK market, at least on paper. Bidirectional DC at up to 12.8 kW means it can discharge your car's battery to power your house during a peak-rate evening, or export to the grid when the price is right. For a household with solar panels, a compatible EV, and a time-of-use tariff like Octopus Agile, the arithmetic could work — eventually.

The demands are steep. The unit costs £6,100 before installation. Installation itself runs £1,500–£3,000 or more, requires a specialist installer, and needs a DNO G99 application with a 30–60 working-day lead time. Total outlay could exceed £9,000. The warranty is 3 years — the same as the Indra at one-fifteenth the price, and shorter than the 5 years offered by the Rolec EVO or the 10 years from Simpson & Partners Home 7. The OZEV grant does not apply.

And the hardest constraint: the car. Bidirectional DC via CCS2 is supported by a handful of vehicles — the Kia EV9 is the headline name. Most UK Teslas, most Volkswagen Group cars, most everything else on British driveways today cannot use the V2H or V2G features. You would be paying £6,100 for a charger whose defining capability depends on a car you may not yet own.

When the Quasar 2 makes financial sense

It needs three things to align. First, a bidirectional-capable car — not "coming soon", but in your driveway. Second, a V2G export tariff that pays enough per kWh to offset the hardware cost within a reasonable timeframe. Third, the patience to navigate G99 approval and a product that is, as of April 2026, still on pre-registration with no confirmed UK shipping date or final GBP price.

If all three are in place, the Quasar 2 is the only mainstream residential product that does what it does. That is a genuine position. But if even one is missing, the money goes further elsewhere. A GivEnergy EV Charger at £444 paired with a home battery gives you time-of-use arbitrage without needing a compatible car. A Zaptec Go 2 at £638 or a NexBlue Point 2 at £534 holds a V2G-ready position at a fraction of the Quasar's cost, ready for the day the ecosystem matures.

The verdict

Buy the Indra Smart PRO if:

• You want a smart charger on the wall for the lowest effective cost, including included SPD and CT clamp
• You charge on a smart tariff and need scheduling that works today, not next year
• You are OZEV-eligible and want the £500 grant to cover the unit and contribute to install

Buy the Wallbox Quasar 2 if:

• You already own or have ordered a bidirectional-capable car like the Kia EV9
• You have a V2G tariff lined up and have done the payback maths on a £7,600+ installed total
• You accept pre-registration status, G99 lead times, and a 3-year warranty on a £6,100 unit

For the overwhelming majority of UK EV owners, the Indra Smart PRO at £395 is the right answer. It charges your car, it talks to your tariff, and it leaves £5,705 in your pocket. The Quasar 2 is a fascinating product aimed at a future that has not quite arrived — and priced as though it already has.
