Andersen Quartz vs Enphase IQ EV Charger 2: Design finish or solar ecosystem?

£695 for the finish, £779 for the ecosystem

Two chargers above £650, neither confirmed for the £500 OZEV grant, and neither the obvious choice for a buyer who simply wants a competent 7kW box on the wall. These are both niche purchases — the question is which niche is yours.

• Andersen Quartz — £695. Eleven finishes, seven-year warranty, IP65, Intelligent Octopus Go integration. A design charger that does the electrical and tariff job properly.
• Enphase IQ EV Charger 2 — £779. Solar-surplus charging from 1.38kW, 1A incremental current control, tight single-app integration with Enphase microinverters and IQ Battery. A charger that exists to complete an Enphase energy system.

What the £84 gap actually buys

The Enphase costs £84 more than the Andersen Quartz. For that money, you get a longer tethered cable (7.5m versus 5.5m standard), MID-certified metering accurate to ±1%, OCPP 2.0.1 support, and ISO 15118 hardware readiness — future-facing specs that look good on paper. You also get a charger that weighs 11kg, carries only a five-year warranty against the Andersen's seven, and drops from IP65 to IP55. In a country where the charger lives outdoors, that IP rating difference is not trivial. IP65 means jet-washed without flinching; IP55 means protected against water jets but not the sustained kind.

What you lose is more pointed. The Enphase has no integration with Intelligent Octopus Go, Octopus Go, Octopus Agile, or OVO Charge Anytime. The Andersen Quartz supports Intelligent Octopus Go and OVO Charge Anytime directly. For any buyer on a smart tariff — and that is most EV owners chasing cheap overnight rates — the Andersen does something useful that the Enphase cannot.

The Enphase case: solar homes, but only *these* solar homes

The Enphase IQ EV Charger 2 can chase solar surplus from as little as 1.38kW, adjusting in 1A increments roughly every 30 seconds. That is genuinely fine-grained solar diversion — better than the Andersen's CT-clamp-based Adaptive Fuse, which works but lacks the same resolution. Paired with Enphase IQ microinverters and an IQ Battery, the charger lets AI-led source selection decide whether your car draws from panels, battery, or grid, all visible in one app.

The catch: that integration requires an Enphase IQ Gateway on site. Without the rest of the Enphase stack, the charger is a £779 7.4kW box with no tariff smarts and an install cost of £900–£1,300 — significantly above the Andersen's £435–£800 range. If you have solar panels but *not* Enphase microinverters, the myenergi Zappi GLO at £750 does solar diversion without locking you into a single manufacturer's ecosystem. And if your priority is tariff optimisation alongside solar, the Ohme Home Pro at £535 handles half-hourly tariffs better than either charger here and costs considerably less.

The Andersen case: looks, warranty, and tariff sense

The Andersen Quartz is the entry point to Andersen's design language — eleven standard finishes, optional Accoya and carbon inserts, compact at 286 × 172 × 110mm. It is not the Andersen A3 with its hidden cable drum, but it is £300 less than the A3 and still looks like something you chose rather than something that was installed.

The seven-year warranty matters. At this price point, you are paying a premium over mainstream chargers — the Hypervolt Home 3 Pro does similar electrical work for £690, and the Tesla Wall Connector for £478 — so the warranty needs to justify the outlay. Seven years does that. Five years, the Enphase's offer, is standard. Nothing wrong with it, but nothing that earns a premium either.

The Andersen also handles tariffs. Intelligent Octopus Go integration means the charger can accept slot allocation from Octopus, charging when rates drop to 7p/kWh without you setting a manual schedule. The Enphase offers no equivalent. For the majority of UK EV owners whose savings come from off-peak electricity rather than rooftop panels, this is the more useful charger.

Which to buy

Buy the Andersen Quartz if:

• You want a charger that looks considered on the wall and carries a seven-year warranty
• You are on or plan to join Intelligent Octopus Go or OVO Charge Anytime
• You have solar but not an Enphase-specific system

Buy the Enphase IQ EV Charger 2 if:

• You already own Enphase microinverters and an IQ Battery and want one app for everything
• Fine-grained solar surplus charging from 1.38kW matters to your daily generation profile
• You value OCPP 2.0.1 and ISO 15118 hardware readiness for future-proofing

For most buyers arriving at this comparison, the Andersen Quartz is the sounder purchase. It costs £84 less, lasts two warranty years longer, weathers better, and talks to the tariffs that save real money. The Enphase is a good charger trapped inside an ecosystem argument — compelling if you are already in that ecosystem, hard to recommend if you are not.
