Indra Smart PRO vs Enphase IQ EV Charger 2: Solar logic or ecosystem lock-in?

The £180 question: open charger or closed ecosystem?

Both the Indra Smart PRO at £599 and the Enphase IQ EV Charger 2 at £779 can chase solar surplus. Both deliver 7.4 kW on single-phase. Both have tethered Type 2 cables. The resemblance ends there. The Indra is a general-purpose smart charger that happens to include solar diversion. The Enphase is a purpose-built node in a proprietary energy system — brilliant inside that system, expensive outside it.

• Indra Smart PRO — £599, OZEV-approved, includes surge protection and CT clamp, integrates with Intelligent Go and Octopus Go. A charger that works for most households.
• Enphase IQ EV Charger 2 — £779, OZEV status unconfirmed, 7.5-metre cable, 1A-increment solar tracking, MID-certified metering. A charger that works superbly for *Enphase* households.

What the Enphase does that the Indra cannot

The Enphase's solar-surplus logic is finer-grained than anything the Indra offers. It adjusts current in 1 A increments roughly every 30 seconds, and it can begin diverting from as little as 1.38 kW of excess PV. Paired with an Enphase IQ Battery and IQ Gateway, the charger lets the app's AI decide whether your car draws from panels, battery, or grid — all visible in one interface. That level of orchestration does not exist on the Indra, or on most chargers at any price.

It also carries a 7.5-metre tethered cable — 1.5 metres longer than the Indra's 6-metre lead. For driveways where the consumer unit sits at the far end of the house, that extra reach can save a wall-mount relocation.

The 5-year warranty is two years longer than the Indra's. And the IP55 / IK10 enclosure rating edges out the Indra's IP54, though in practice either is fine on a UK exterior wall.

What the Indra does that the Enphase cannot

The Indra talks to UK smart tariffs. It integrates with Intelligent Octopus Go, Octopus Go, OVO Charge Anytime, and EDF GoElectric. The Enphase has no direct API link to any half-hourly or off-peak UK tariff. If you are not running Enphase solar, the Enphase charger is a £779 box that schedules via a timer — and for that, a Sync Energy Wall Charger 2 does the same job for £362.

Then there is install cost. The Indra ships with a surge protection device (SPD) in the box — a component most electricians would otherwise add for £100–£150. It also includes the CT clamp for solar, saving another £50–£100. Indra quotes from £899 fully installed. The Enphase's typical install runs £900–£1,300, partly because its 11 kg weight and Enphase Gateway requirement add labour. The all-in gap between the two can reach £400–£500 once the sparks have left.

And the Indra is OZEV-approved. Eligible renters and flat owners can claim the £500 grant, which covers most of the £599 unit price and contributes to install costs. The Enphase's OZEV status is unconfirmed — a risk worth checking before you commit.

When the Enphase earns its premium

There is exactly one scenario where the Enphase justifies £779: you already own Enphase microinverters, an IQ Gateway, and ideally an IQ Battery. In that context, the charger slots into a single-app energy system that no competitor replicates. The 1A solar tracking is measurably tighter than the Indra's CT-clamp approach. The MID-certified metering gives you ±1% accuracy on every kWh — useful if you are tracking self-consumption closely.

If you have solar panels but *not* Enphase hardware, the myenergi Zappi GLO at £750 is a more versatile solar charger with OZEV approval and a larger installer network. Solar buyers weighing those options may find the Zappi GLO vs Indra Smart PRO comparison more useful.

The verdict

Buy the Indra Smart PRO if:

• You want smart-tariff scheduling with Intelligent Go, Go, or OVO Charge Anytime
• You want the lowest total installed cost, thanks to the included SPD and CT clamp
• You are eligible for the £500 OZEV grant and want a confirmed-approved charger

Buy the Enphase IQ EV Charger 2 if:

• You already run Enphase microinverters and an IQ Gateway
• Single-app control over panels, battery, and car matters more than tariff automation
• The 7.5-metre cable solves a specific reach problem the Indra's 6-metre lead does not

For most buyers — including most solar households — the Indra is the sounder purchase. It costs £180 less at the unit, potentially £400+ less installed, and it plays nicely with the UK's best off-peak tariffs. The Enphase is a fine piece of hardware trapped inside a narrow use case. Unless your roof is already covered in Enphase kit, the maths do not add up.
