Andersen Quartz vs Enphase IQ EV Charger 2

£672 against £1,050 — and why the gap is wider than it looks

The Andersen Quartz and the Enphase IQ EV Charger 2 are not competitors in any ordinary sense. One is a design-led home charger that happens to do solar diversion. The other is the final node in an Enphase energy system that happens to charge a car. The £378 between them is not a feature premium — it is the price of ecosystem loyalty.

• Andersen Quartz — £672. Eleven finishes, seven-year warranty, IP65, Intelligent Octopus Go integration. A handsome charger that does the job and looks good on the wall.
• Enphase IQ EV Charger 2 — £1,050. Solar-surplus charging from 1.38kW, AI source selection across panels, battery and grid — but only if you already have an Enphase IQ Gateway and the rest of the Enphase stack.

The Enphase only earns its price inside an Enphase house

Strip away the ecosystem and the Enphase is a 7.4kW tethered charger with a 5-year warranty, IP55 rating, and no smart-tariff integration. At £1,050, that is expensive by any measure. The Ohme Home Pro does more with tariffs for £539. The Hypervolt Home 3 Pro is a stronger all-rounder at £625. Even the Tesla Wall Connector — £475, no OZEV approval either — undercuts it by £575.

Where the Enphase becomes a different proposition entirely is in a home already running Enphase microinverters and an IQ Battery. There, the charger draws surplus solar from as little as 1.38kW, adjusting current in 1A increments roughly every 30 seconds. The Enphase app governs panels, battery and car in one view, with AI-led source selection deciding whether to pull from the roof, the wall or the grid. That is a genuinely integrated energy system, and no other UK home charger replicates it at that level of granularity within Enphase's own stack.

The catch: you need the Gateway on site, and the total system cost — panels, battery, gateway, charger — runs well into five figures. The charger is the cheap part.

The Andersen Quartz does more for less — and covers more tariffs

The Andersen Quartz is not cheap either, at £672. But it brings a seven-year warranty (two years longer than the Enphase), IP65 weatherproofing (a grade above IP55), and a compact 286 × 172 × 110 mm body in eleven standard finishes. It integrates with Intelligent Octopus Go and OVO Charge Anytime — two tariffs the Enphase cannot talk to at all.

It also includes a CT clamp for solar diversion via its Adaptive Fuse feature. The tracking is not as fine-grained as the Enphase's 1A increments from 1.38kW, but it works with any solar installation, not just Enphase's. If solar charging matters and you do not run Enphase panels, the Andersen handles it — and the myenergi Zappi GLO at £599 handles it better still. Our solar charger guide covers the field in more detail.

Neither charger has confirmed OZEV approval, so the £500 grant is not guaranteed for either. That is worth checking before you commit, particularly at the Enphase's price point.

Install costs widen the gap further

The Andersen Quartz typically installs for £435–£800. The Enphase IQ EV Charger 2 runs £900–£1,300 — partly because the installer often needs to configure the Gateway integration and verify the whole Enphase system communicates correctly. Add unit to install and you are looking at roughly £1,100–£1,470 all-in for the Andersen, against £1,950–£2,350 for the Enphase. That is a meaningful difference for a pair of single-phase 7kW-class chargers doing the same electrical job.

Which to buy

Buy the Andersen Quartz if:

• You want a good-looking charger with a seven-year warranty and do not run Enphase solar
• You use or plan to use Intelligent Octopus Go or OVO Charge Anytime
• You want solar diversion that works with any panel brand, not just one

Buy the Enphase IQ EV Charger 2 if:

• You already own Enphase microinverters, an IQ Battery, and an IQ Gateway
• Single-app control over panels, battery and car is worth the £378 premium to you
• You do not need smart-tariff integration — your savings come from the roof, not the grid

For the vast majority of buyers, the Andersen Quartz is the sounder purchase. It costs £378 less, lasts two warranty years longer, weathers worse walls, and talks to the tariffs most EV owners actually use. The Enphase is a fine piece of hardware locked behind a system requirement most homes do not meet. If yours does, it earns its place. If it does not, you are paying £1,050 for a charger that several £500-range alternatives outperform.
