Indra Smart PRO vs Rolec EVO: British-Built Value Showdown

Two British Underdogs Go Head to Head — Which Delivers More for Less?

If you've narrowed your shortlist to the Indra Smart PRO and the Rolec EVO, you're clearly someone who values substance over hype. Neither of these chargers comes from the household names that dominate EV charging conversations — you won't find them plastered across Tesla forums the way an Ohme or myenergi might be. But both are designed and manufactured right here in the UK, both pack in solar integration and dynamic load balancing as standard, and both aim to save you money not just on your electricity bill but on installation day too.

The question is whether the Rolec EVO's aggressive £449 price tag and longer warranty make it the smarter buy, or whether the Indra Smart PRO's included surge protection device and tethered convenience justify the £150 premium. Let's dig into the details.

In a nutshell:

• Indra Smart PRO (£599): A tethered, British-made charger whose included SPD genuinely reduces installation costs, with smart tariff integration and a clear path into Indra's V2G ecosystem.
• Rolec EVO (£449): A feature-packed untethered charger with built-in PME fault detection, solar Eco modes, OCPP support, and a 5-year warranty — all at a price that embarrasses much of the competition.

Spec Comparison

Smart Tariff Integration and Scheduling

Both chargers support scheduled charging, which is essential if you're on one of the UK's growing number of EV-specific tariffs. The Indra Smart PRO explicitly advertises smart tariff integration with major UK energy providers, making it straightforward to set your car to charge during Octopus Go's 7.5p/kWh window (00:30–04:30) or similar off-peak slots on OVO Smart Charge and British Gas Electric Driver. According to topcharger.co.uk, the Indra's tariff mode lets you input your specific tariff details so charging automatically starts when the cheap rate kicks in — a genuinely useful feature that removes the need to set manual timers.

The Rolec EVO offers charge scheduling through its app, and its OCPP 1.6J support opens the door to third-party energy management platforms down the line. However, its tariff integration isn't as explicitly baked in as the Indra's dedicated tariff mode. If you're the sort of person who wants to set and forget your off-peak charging with minimal fuss, the Indra has a slight edge here.

On a practical level, charging a typical 60kWh Tesla Model 3 battery from 20% to 80% on either charger takes roughly 5 hours at 7.4kW — comfortably within any overnight off-peak window. At Octopus Go rates, that session costs around £2.70 compared to roughly £10 at the standard variable rate. Over 7,400 miles of annual driving, that's savings of approximately £300–£400 per year.

Solar Integration

Both chargers include a CT clamp for solar diversion at no extra cost, which is a genuine bonus — some competitors charge £50–£100 for this accessory. The Rolec EVO distinguishes itself with two dedicated solar modes: Eco mode, which blends solar and grid power to maintain a steady charge, and Eco+ mode, which charges exclusively from solar surplus. This dual-mode approach gives you more granular control over how green (and how cheap) your charging sessions are.

The Indra Smart PRO also supports solar matching, and electriccarguide.co.uk notes that its solar power matching works well in practice. However, the Rolec's Eco/Eco+ distinction is a more refined implementation that solar panel owners will appreciate, particularly during the summer months when surplus generation can comfortably handle a full charging session.

If you've got a 4kW+ solar array on your roof, the Rolec EVO's solar modes arguably represent the more sophisticated solution.

Build Quality and Installation Considerations

The Rolec EVO is impressively compact at just 3 kg and 260 × 260 × 112mm, with an IK10 impact rating — the highest available — meaning it can withstand a 20-joule impact. It also won a Red Dot Design Award in 2024, which tells you something about its aesthetics. The IP54 weatherproofing is identical on both units and perfectly adequate for a typical UK outdoor installation.

The Indra Smart PRO is a larger, heavier unit at 5 kg, but it includes a surge protection device (SPD) as standard. Since the 18th Edition wiring regulations effectively require SPDs for new EV charger installations, this inclusion genuinely saves you £100–£150 on installation costs. The Rolec EVO counters with built-in PME/PEN fault detection and a Type A RCD with 6mA DC protection, which can eliminate the need for a separate PEN device or earth rod — a saving of £100–£200 depending on your installer and local ground conditions.

Both chargers, then, include components that reduce installation costs, but in different ways. The Rolec's built-in PEN fault detection is arguably the more valuable saving, as earth rod installations can be particularly expensive in areas with rocky or shallow soil. As electriccarguide.co.uk notes, the Indra range includes O-PEN fault detection as well, but the Smart PRO data provided doesn't explicitly confirm this is built into the unit itself.

One significant practical difference: the Indra Smart PRO comes tethered with a 6-metre Type 2 cable permanently attached. The Rolec EVO is untethered only, meaning you'll need to plug in your own cable each time. For many Tesla owners who keep a cable in the boot anyway, this is no hardship. But if you want the grab-and-go convenience of a tethered charger — especially in the rain — the Indra wins on daily usability.

App and Connectivity

The Rolec EVO takes a clear lead on connectivity hardware: Wi-Fi 6, Bluetooth 5.0, and a wired Ethernet port give you three reliable connection options. The Indra Smart PRO offers Wi-Fi and Bluetooth, which is perfectly adequate for most homes but lacks the Ethernet fallback that can be invaluable in garages with thick walls or poor Wi-Fi coverage.

Both chargers are controlled via their respective apps — the Indra app and the Rolec EVO app. Neither is considered best-in-class; the Indra's app has been described as basic compared to market leaders like Ohme, while the Rolec EVO's app is still maturing as a newer product. If app polish is a priority, neither charger will blow you away, but both handle the essentials: scheduling, energy monitoring, and charging status.

Price and Value

The £150 price gap is significant. Even accounting for the Indra's included SPD (saving ~£100–£150), the Rolec EVO matches or beats it on effective cost thanks to its own built-in PEN fault detection savings. The Rolec also throws in a 5-year warranty versus the Indra's 3 years, two RFID cards, and OCPP support — features that collectively represent outstanding value at £449.

Who Should Buy Which?

Buy the Indra Smart PRO if:

• You want a tethered charger with a permanently attached cable for daily convenience
• Smart tariff integration with a dedicated tariff mode is a priority
• The included SPD matters for your specific installation requirements
• You're interested in Indra's broader ecosystem and potential future V2G developments
• You prefer a British brand with a focused EV charging heritage

Buy the Rolec EVO if:

• You want the best feature-to-price ratio currently available in the UK market
• You have solar panels and want dedicated Eco and Eco+ charging modes
• A 5-year warranty gives you peace of mind over a 3-year one
• Built-in PEN fault detection and RCD protection matter for reducing your installation bill
• You value connectivity options including Wi-Fi 6 and Ethernet

Our recommendation: For most UK Tesla owners, the Rolec EVO is the stronger buy. It delivers a more comprehensive feature set at £150 less, backs it with a longer warranty, and its built-in safety features can save as much on installation as the Indra's included SPD. The untethered design is the main compromise, but if you can live with plugging in a cable each time, the EVO's value proposition is genuinely hard to beat. The Indra Smart PRO remains a solid choice if you specifically want a tethered charger or if its tariff mode integration aligns perfectly with your energy setup — but on pure value, the Rolec takes this one.
