Indra Smart LUX vs Enphase IQ EV Charger 2

£504 is a lot of money to spend on an ecosystem

The Indra Smart LUX costs £546. The Enphase IQ EV Charger 2 costs £1,050. Both deliver 7.4 kW on a single-phase supply. Both are tethered Type 2 units with IK10 impact ratings and built-in PEN fault detection. The gap between them — £504 — is larger than many standalone chargers on the market. That gap buys precisely one thing: membership of the Enphase energy ecosystem.

• Indra Smart LUX — £546, OZEV-approved, IP67, 78 mm deep, solar diversion via CT clamp, integration with 1,000+ UK tariffs. The charger that does everything independently.
• Enphase IQ EV Charger 2 — £1,050, OZEV approval unconfirmed, 7.5 m cable, solar chase from 1.38 kW surplus, single-app control — but only alongside Enphase microinverters and an IQ Gateway.

When the Enphase earns its price

The Enphase has a narrow, specific strength: if your roof already carries Enphase IQ microinverters and you have an IQ Battery in the garage, this charger slots into the same app and the same control logic. It adjusts current in 1A increments roughly every 30 seconds, chasing solar surplus down to 1.38 kW. The AI-led source selection across solar, battery and grid is tidy engineering. MID-certified metering at ±1% accuracy is a nice touch for anyone tracking self-consumption closely. The 7.5-metre cable is generous — 1.5 metres longer than the Indra's standard tether.

Outside that context, the argument collapses. The Enphase has no direct integration with Octopus Agile, Octopus Intelligent Go, or any other half-hourly UK tariff. It requires an Enphase IQ Gateway on site to behave as advertised. Its OZEV approval is unconfirmed, which means the £500 grant — available to eligible renters and flat owners — may not apply. At £1,050 for the unit alone, with install costs of £900–£1,300, the all-in figure approaches £2,000. That is a hard number to justify for a 7.4 kW home charger.

What the Indra does that the Enphase cannot

The Smart LUX claims integration with over 1,000 UK energy tariffs, including Agile-style half-hourly scheduling. The Enphase offers nothing comparable. For a buyer on Octopus Go or EDF GoElectric, the Indra can schedule charging into the cheapest window automatically. The Enphase cannot — not without manual scheduling through its own app, disconnected from the tariff itself.

Solar diversion on the Indra works via an included CT clamp. It is not as granular as the Enphase's 1A-increment tracking, but it does not require £5,000 worth of Enphase hardware upstream to function. The Indra is also OZEV-approved, so grant-eligible buyers can knock £500 off the £546 unit price — the grant covers the unit outright and chips into the install costs too.

Physically, the Indra is the more resilient product. IP67 against water — submersible, not just splash-proof — versus the Enphase's IP55. At 78 mm deep and 3.6 kg, it sits almost flush against the wall. The Enphase is 118 mm deep and 11 kg. Neither measurement is disqualifying, but if the charger sits on an exposed exterior wall, the Indra's protection rating is materially better.

The trade-off: the Indra's standard warranty is three years, extendable to five for £100. The Enphase includes five years from the outset. And the Indra's 4G connectivity option costs an extra £250 — a sting when chargers like the Ohme Home Pro include a SIM as standard at £539.

Better solar alternatives for less

Buyers drawn to the Enphase for its solar-surplus charging but who do not own Enphase panels should look elsewhere. The myenergi Zappi GLO at £599 is purpose-built for solar diversion, brand-agnostic, OZEV-approved, and available with a three-phase option. It does the solar job better than the Enphase for £451 less. For those with a GivEnergy battery system, the GivEnergy EV Charger at £444 offers comparable ecosystem integration at a fraction of the cost. Our solar charger guide covers the full field.

The verdict

Buy the Indra Smart LUX if:

• You want tariff integration, solar diversion and robust build quality for £546
• You are OZEV-eligible and want the grant to cover the unit price entirely
• Your charger sits on an exposed wall and IP67 protection matters

Buy the Enphase IQ EV Charger 2 if:

• You already own Enphase microinverters and an IQ Battery and want single-app control
• MID-certified metering and 1A-increment solar tracking are priorities
• You accept the £1,050 price as the cost of ecosystem coherence

For the vast majority of UK buyers — including those with solar panels from any other manufacturer — the Indra Smart LUX is the better charger at less than half the price. The Enphase is a fine piece of hardware trapped inside a narrow use case. If you do not already live inside the Enphase ecosystem, there is no reason to start here.
