Enphase IQ EV Charger 2 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 £5,050 gap — and a category boundary

Placing the Enphase IQ EV Charger 2 next to the Wallbox Quasar 2 is less a comparison than a taxonomy exercise. One is a 7.4 kW AC wallbox that happens to talk fluently to Enphase solar kit. The other is a 12.8 kW bidirectional DC unit that can push power back from your car into your house or the grid. The Enphase costs £1,050. The Quasar 2 costs £6,100 — and you cannot yet order it in the UK.

• Enphase IQ EV Charger 2 — a solar-ecosystem charger. Charges the car from surplus PV as low as 1.38 kW, integrates tightly with Enphase microinverters and IQ Battery, and does nothing the car can't already do with electrons: receive them.
• Wallbox Quasar 2 — a bidirectional DC charger. Sends power to the car and draws it back for home backup or grid export via CCS2. A different animal entirely.

Who the Enphase is for — and who it isn't

The Enphase makes its case in a single scenario: you already own Enphase IQ microinverters and, ideally, an IQ Battery. In that context, the charger slots into the Enphase app as a fourth node — panels, battery, home, car — with AI-led source selection and 1A-increment solar tracking every thirty seconds. The 7.5-metre tethered cable is among the longest on the UK market, and the built-in MID-certified meter means accurate self-consumption data without an add-on CT clamp.

Outside an Enphase system, the argument thins. At £1,050, the unit alone costs roughly double a Wallbox Pulsar Max at £513 or a Hypervolt Home 3 Pro at £625 — both OZEV-approved, both smart, both cheaper installed. The Enphase lacks direct integration with Octopus Intelligent Go, Octopus Agile, or any half-hourly UK tariff. If solar diversion matters but Enphase hardware does not, the myenergi Zappi GLO does the job for £599 and carries OZEV approval. For a fuller look at that pairing, see the Zappi GLO vs Enphase comparison.

What the Quasar 2 promises — and what it asks in return

The Quasar 2 is the reference product for residential V2H and V2G in the UK. Up to 12.8 kW bidirectional DC through a CCS2 connector means, in principle, your car becomes a home battery. A 64 kWh Kia EV9 could back up a typical household for a day or more during a power cut, or export to the grid on a V2G tariff during peak pricing.

The cost of that promise is steep. The £6,100 unit price — converted from the European list, UK RRP still unconfirmed — is only the start. Installation runs £1,500–£3,000+, a DNO G99 application adds 30–60 working days of lead time, and the installer pool is thin. The warranty is three years, shorter than the Enphase's five and shorter than several AC chargers at a tenth of the price. The £500 OZEV grant does not apply to bidirectional DC units. And the list of cars that can actually use bidirectional DC remains short — the Kia EV9 is the headline; most UK EVs cannot participate.

The honest maths: the Quasar 2 installed will likely cost £7,600 or more. A decent AC wallbox plus a dedicated home battery — say a GivEnergy EV Charger at £444 paired with a GivEnergy battery — delivers home backup and solar storage for considerably less, without needing the car parked on the drive to keep the lights on.

Neither charger qualifies for the grant

Both the Enphase and the Quasar 2 sit outside the £500 OZEV grant. The Enphase's approval is unconfirmed; the Quasar 2, as a bidirectional DC unit, is ineligible outright. Grant-eligible renters and flat owners looking for solar integration would do better with the Zappi GLO or the Ohme Home Pro — both approved, both hundreds less.

The verdict

Buy the Enphase IQ EV Charger 2 if:

• You already run Enphase IQ microinverters and want one app for panels, battery, and car
• You value MID-certified metering and 1A solar-tracking granularity
• You accept paying a premium for ecosystem coherence over tariff smarts

Buy the Wallbox Quasar 2 if:

• You own (or have ordered) a CCS2-compatible bidirectional car — today, that largely means the Kia EV9
• You want true vehicle-to-home backup, not just AC charging
• You are comfortable with pre-registration timelines, G99 paperwork, and a total outlay north of £7,600

For most UK EV owners arriving at this page, the answer is neither. The Enphase is expensive without Enphase solar. The Quasar 2 is expensive full stop — and not yet available. If you want a well-priced smart charger that works with any car and any tariff, the Ohme Home Pro at £539 or the Hypervolt Home 3 Pro at £625 will serve you better and sooner. The Quasar 2 is a product for a future that is arriving slowly. The Enphase is a product for a present that only some households share.
