myenergi Zappi GLO
Quick summary: The myenergi Zappi GLO is a 7kW / 22kW myenergi home charger priced at £779, with a 3 years warranty and a 4.6/5 rating. Best for solar. Installation costs £400–600 and it's compatible with all Tesla models via the standard Type 2 connector.
The myenergi Zappi GLO is the undisputed champion for solar panel owners in the UK. It offers three distinct charging modes -- Fast (full power from the grid), Eco (a blend of solar and grid power that tops up from the grid when solar drops below a threshold), and Eco+ (100% surplus solar only, giving you completely free charging when the sun is producing enough). No other charger on the market does solar diversion this well or with this level of granularity. The GLO is the 2025 successor to the popular Zappi 2.1, ditching the built-in screen for a cleaner, more modern design controlled entirely through the myenergi app. What makes the Zappi truly special is its ecosystem: pair it with an eddi to divert surplus solar to your hot water tank, or a libbi battery to store solar energy for overnight EV charging. It is an entire home energy management system, not just a charger. At £779 it is the most expensive unit on this list, but if you have solar panels the investment pays for itself through free charging on sunny days.
Best for: Solar panel owners who want the most sophisticated solar diversion on the market and the option to build a complete home energy ecosystem.
Installation
The Zappi GLO weighs 5.4 kg and measures 439mm x 282mm x 130mm, making it one of the larger chargers on the market. The 6.5-metre tethered cable is a good middle ground -- shorter than the Tesla Wall Connector's 7.3 metres but longer than the Ohme's standard 5 metres. For solar diversion to work, the installer needs to fit a myenergi CT clamp (current transformer) to your electricity meter tails, which reads your home's energy import and export in real time. This is a standard part of a Zappi installation and most myenergi-accredited installers will include it as part of the job. The charger requires a dedicated 32A circuit. It does not include a built-in RCD or SPD, so these will need to be added at the consumer unit. The GLO is IP65 rated, making it fully weatherproof for exposed outdoor mounting. It is also available in an untethered version if you prefer a socket-only installation.

Tariff Compatibility
The Zappi GLO supports smart tariff scheduling through the myenergi app, with direct compatibility with Octopus Intelligent Go and Octopus Go. You can set charging schedules to match your off-peak window, and the charger will only draw from the grid during those hours. However, the Zappi's tariff integration is not as seamless as the Ohme Home Pro's. Where the Ohme communicates directly with Octopus via API to request extra off-peak slots and optimise for half-hourly pricing on Agile, the Zappi relies on manual schedule setting. For Zappi owners, the real cost saving comes from solar, not tariff optimisation. In Eco+ mode, every kilowatt-hour comes from your panels at zero marginal cost, which beats even the cheapest off-peak tariff rate. The ideal setup is Eco+ during the day (free solar) and a scheduled off-peak slot overnight (cheap grid).

Price Breakdown
| Cost element | Amount |
|---|---|
| Unit price | £779 |
| Typical installation | £400--600 |
| Total installed cost | £1,179--1,379 |
| After OZEV grant (renters/flat owners) | £829--1,029 |
The Zappi GLO is the most expensive charger on this list at £779 for the unit alone. That is a significant premium over the Tesla Wall Connector (£475) and the Ohme Home Pro (£535). However, the maths changes dramatically if you have solar panels. A typical 4kW solar array in the south of England generates enough surplus energy to charge a Tesla Model 3 for roughly 8,000--10,000 miles per year for free in Eco+ mode. At the standard electricity rate of around 24p/kWh, that is worth £500--600 per year in avoided charging costs. The Zappi's premium over a basic charger pays for itself within 12 months for most solar households. For details on eligibility, see our OZEV grant guide.
How It Compares
The Zappi GLO's main rivals are the Tesla Wall Connector (if you do not need solar) and the Hypervolt Home 3 Pro (which offers basic solar diversion at a lower price). For a full breakdown of solar capabilities, see our Zappi GLO vs Hypervolt Home 3 Pro comparison. If you are torn between solar features and budget, our Zappi GLO vs GivEnergy EV Charger comparison covers the differences between dedicated solar diversion and battery-to-EV charging. The Zappi also competes with the EO Mini Pro 3 on solar -- see our Zappi GLO vs EO Mini Pro 3 comparison for a side-by-side on solar features versus compact size.

Specifications
Pros
- +Best-in-class solar diversion with three modes — Eco+ charges entirely from surplus solar for free
- +Part of the myenergi ecosystem (eddi hot water diverter, libbi battery) for whole-home energy management
- +Intelligent Octopus Go compatible for cheapest grid charging
- +RFID access supports up to 126 users — useful for shared driveways or small businesses
- +Available in tethered and untethered versions
- +IP65 rated — fully weatherproof
- +35% lower embodied carbon than the previous Zappi 2.1
Cons
- -Most expensive charger at £779 unit-only — the solar features only justify this if you actually have solar panels
- -No built-in 4G — relies on Wi-Fi connectivity
- -The myenergi app has improved but still isn't as polished as Ohme's or Tesla's
- -Screen removed in the GLO version — some users preferred the on-unit display of the older Zappi 2.1
Our Verdict
If you have solar panels, buy the Zappi GLO. Full stop. No other charger matches its solar diversion capabilities, and the myenergi ecosystem lets you build a complete home energy system over time. If you don't have solar panels, this charger is overpriced — the Ohme Home Pro or Tesla Wall Connector are better choices for grid-only charging.
