myenergi Zappi GLO 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 solar charger versus a power station that isn't here yet

These two products do not compete in any normal sense. The myenergi Zappi GLO costs £599, charges your car from the grid or your roof, and ships tomorrow. The Wallbox Quasar 2 costs £6,100, promises to push power back from your car into your house or the grid, and — as of April 2026 — is a UK pre-registration page with a "keep me updated" button. The gap between them is £5,501 and, more importantly, several years of market readiness.

• Zappi GLO — £599, AC charger with best-in-category solar diversion. Works now. OZEV-approved.
• Quasar 2 — £6,100, bidirectional DC unit for V2H and V2G. Pre-registration only. Not OZEV-approved.

What the Zappi GLO does that you can use today

The Zappi GLO exists to solve one problem well: matching your car's charging to your solar generation. Eco+ mode draws only from surplus panel output — nothing from the grid. Eco mode blends grid and solar to maintain a minimum charge rate. Both modes work through the myenergi app and integrate with the wider myenergi ecosystem — the eddi for hot-water diversion, the libbi for home battery storage. If your roof generates it, the Zappi decides where it goes.

At £599, this is not cheap by AC charger standards. A Sync Energy Wall Charger 2 costs £400; a VCHRGD Seven Pro costs £430. The Zappi's premium buys solar intelligence. Without panels, the premium buys you nothing — an Ohme Home Pro at £539 handles smart tariffs more adeptly, and the Zappi's lack of built-in 4G means it depends on your home Wi-Fi reaching the driveway. For solar homes, though, the Zappi GLO remains the reference product. Our solar charger guide covers the alternatives in full.

What the Quasar 2 promises — and what it requires

The Quasar 2's proposition is different in kind. It is a bidirectional DC charger: up to 12.8 kW flowing either direction through a CCS2 connector. In V2H mode, your car becomes a backup battery for the house. In V2G mode, it exports to the grid, potentially earning revenue on a time-of-use tariff like Octopus Agile.

The list of dependencies is long. Your car must support bidirectional DC — today that means the Kia EV9 and a small handful of others. Your DNO must approve a G99 application, a process taking 30–60 working days with a possible G100 export cap. Installation is specialist work, not a standard wallbox fit: expect £1,500–£3,000+ on top of the £6,100 unit price, putting the total above £7,600. The £500 OZEV grant does not apply. And the 3-year warranty — the same length as the Zappi GLO's — covers a unit that costs more than ten times as much.

None of this makes the Quasar 2 a bad product. It makes it an early-adopter product. The technology is real; the ecosystem around it is not mature. The NexBlue Point 2 at £534 publishes ISO 15118 communication support, but that is not bidirectional conversion or a no-upgrade promise. The Indra Smart PRO at £395 is a one-way AC charger.

The maths of waiting versus buying

A solar household installing the Zappi GLO today — £599 hardware, perhaps £500 for a standard install — is operational for around £1,100. With decent panel output and Eco+ mode, a meaningful share of annual charging comes from the roof at zero marginal cost. Pair it with an off-peak tariff like EDF GoElectric at 6.99p/kWh for overnight top-ups, and the running costs are negligible.

The Quasar 2 household, by contrast, faces £7,600+ before a single kilowatt-hour flows in either direction — and the car must be parked at home to serve as a battery. A dedicated home battery (from myenergi's libbi range or GivEnergy's ecosystem via the GivEnergy EV Charger) plus an AC wallbox will cost less, store energy without immobilising the car, and work with every EV on the market. The Quasar 2 only wins the arithmetic when V2G export tariffs pay enough to offset the hardware premium and your car supports bidirectional DC. That combination exists for a few hundred UK households at best.

The verdict

Buy the myenergi Zappi GLO if:

• You have solar panels and want to charge from them automatically
• You want a charger you can order, install, and use this month
• You value the myenergi ecosystem — eddi, libbi, single-app control

Buy the Wallbox Quasar 2 if:

• You own (or have ordered) a CCS2 car with confirmed bidirectional support
• You have a V2G tariff and DNO approval already in progress
• You understand this is a £7,600+ investment with a short warranty and a short compatible-car list

For the vast majority of UK homes — solar or otherwise — the Zappi GLO is the sensible wall-mounted purchase. The Quasar 2 is a fascinating piece of hardware aimed at a future that has not quite arrived. When it does, this comparison will read differently. Today, it reads like £599 versus a waiting list.
