myenergi Zappi GLO vs Indra Smart LUX: Solar Showdown or Slim Design Win?

Two Solar-Capable Chargers at £600 — Which Actually Deserves Your Money?

The myenergi Zappi GLO and Indra Smart LUX land at almost identical price points — £599 and £615 respectively — and both promise solar diversion, smart tariff support, and solid build quality. On paper, they look like direct rivals. In practice, they're designed around quite different priorities.

In a nutshell:

• myenergi Zappi GLO: The solar specialist with an unmatched energy ecosystem behind it
• Indra Smart LUX: The slim, tough all-rounder with the widest tariff compatibility in the UK

Is the Zappi GLO's Solar Diversion Actually Better?

Both chargers can divert surplus solar energy into your car. But the depth of that capability is not equal.

The Zappi GLO offers three charging modes: Fast (full power from the grid), Eco (a blend of solar and grid), and Eco+ (charges exclusively from surplus solar — zero grid draw). That Eco+ mode is genuinely unique. No other mainstream home charger matches it. And if you've already got a myenergi eddi diverting excess solar to your hot water tank, or a libbi home battery, the Zappi GLO slots into that ecosystem seamlessly. Your entire home energy strategy lives in one app.

The Indra Smart LUX does include a CT clamp for solar surplus diversion, and it works. But it doesn't offer the same granular control or the broader ecosystem play. If solar is your primary motivation for spending £600 on a charger, the Zappi GLO is the obvious choice. Our best EV charger for solar guide goes deeper on this.

Does the Indra Smart LUX Justify Its Price Without Solar?

Here's where the Indra starts to carve out its own territory. At just 78mm deep and 3.6 kg, it's the slimmest tethered smart charger you can buy in the UK. If your charger needs to sit on a narrow wall, beside a garage door, or somewhere aesthetically sensitive, this matters more than you'd think.

Then there's durability. IP67 plus IK10 is overkill for most driveways — but overkill is reassuring. IP67 means it can survive temporary submersion; IK10 means it'll shrug off a stray football or a reversing mishap. The Zappi GLO's IP65 is perfectly fine for UK weather, but the Indra's rating is a class above.

The Indra also comes with built-in SPD and PEN fault detection as standard, which can simplify installation and potentially shave cost off your electrician's bill. Its quoted installation range of £300–500 reflects that — slightly lower than the Zappi's £400–600 estimate.

Smart Tariff Support: Indra Casts a Wider Net

The Zappi GLO works with Intelligent Octopus Go, which is excellent if you're on that specific tariff. But the Indra Smart LUX integrates with over 1,000 UK energy tariffs, including Octopus Agile's half-hourly variable pricing. That breadth matters if you're not with Octopus, or if you switch providers regularly.

For anyone focused purely on squeezing every penny from their electricity bill across multiple tariff types, the Indra's flexibility is a real advantage. Check our EV tariff comparison to see which tariffs each charger supports.

That said, neither charger's app is best-in-class. The myenergi app has improved considerably but still feels a step behind the slickest competitors. The Indra app is functional and supports OTA updates and OCPP 1.6, which future-proofs it nicely — but don't expect a premium software experience from either.

The 4G and Warranty Question

Both chargers rely on Wi-Fi as standard. The Indra offers optional 4G connectivity, but it costs an additional £250 — a steep add-on that pushes the total cost well past the Zappi GLO. The Zappi has no 4G option at all.

Warranties are identical at three years, but the Indra lets you extend to five years for £100 extra. The Zappi GLO doesn't offer an extension. If long-term peace of mind matters, that's £100 well spent on the Indra — though it does mean the total outlay creeps towards £715 for the extended warranty model.

Which Should You Buy?

Buy the myenergi Zappi GLO if:

• You have solar panels and want the best surplus diversion on the market
• You already own (or plan to buy) other myenergi products like eddi or libbi
• You want the option of an untethered socket version
• Eco+ mode — charging entirely from free solar — appeals to you

Buy the Indra Smart LUX if:

• Wall space is limited and the 78mm slim profile matters
• You want the toughest build quality available (IP67 + IK10)
• You're on a non-Octopus tariff or want the widest possible tariff support
• Built-in SPD and PEN fault detection could reduce your installation cost

For most Tesla owners with solar panels, the Zappi GLO remains the default recommendation — its three-mode solar diversion is unmatched, and the myenergi ecosystem gives it a long-term upgrade path nothing else offers. Without solar, the calculus shifts. The Indra Smart LUX is a beautifully engineered, UK-made charger that's tougher, thinner, and more tariff-flexible. At this price, neither is a mistake — but knowing which strength matters to you makes the decision straightforward. For more options, see our best smart EV charger guide.
