Is the myenergi zappi compatible with Tesla?

Yes. The myenergi zappi uses the Type 2 connection used by UK Tesla models. Actual AC charging speed is limited by the lower of the vehicle's onboard-charger limit, the property's supply and the charger's 7kW single-phase capability.

What warranty does the myenergi zappi come with?

The myenergi zappi comes with a 3 years (5 with £120 extension) warranty. It is currently recorded as OZEV-approved; the property, vehicle and installer must also meet the grant rules.

What is the power output of the myenergi zappi?

The myenergi zappi supports 7kW on single phase and up to 22kW on a suitable three-phase supply. A 20–80% time depends on the Tesla model's usable battery capacity and AC limit as well as the available supply.

Can the myenergi zappi charge from solar panels?

Yes. The myenergi zappi has native solar support and can prioritise measured surplus generation for the car when the required metering is installed.

Does the myenergi zappi work with smart energy tariffs?

The myenergi zappi can integrate directly with supported supplier tariffs. Compatibility, eligibility and rates vary by provider, so confirm the specific tariff before switching.

The installed range is an estimate. The source date above is separate from the editorial review date.

The original solar charger, still on sale beside its cheaper sibling. myenergi now sells two zappis: this one — the 2.1, with the backlit LCD, the buttons and the full menu — and the screenless zappi GLO at £599. myenergi's own framing is that the standard zappi is for people who want to "deep dive into settings", the GLO for those who don't. The settings are the point. Eco mode blends solar with up to 1.4 kW of grid; Eco+ charges from surplus only; a Min Green Level slider lets Eco+ start on a partly cloudy day rather than waiting for the full 1.4 kW of export. The GLO has Eco+ and a timer, and none of the rest.

It is also the only zappi with a 22 kW three-phase version and an Ethernet port, and the only one in white. What it shares with the GLO is the ecosystem — eddi for hot water, libbi for storage — and the tariff links, which are now the best on the market outside Ohme.

Best for: Solar households that want to see and tune what the charger is doing on the wall, and anyone needing 22 kW or a wired network connection.

Installation

Fitting the myenergi zappi.

438 × 282 × 122 mm, IP65 and IK10; 5.5 kg tethered on single-phase, 3.0 kg untethered. The installer fits one grid CT clamp on the meter tails (three on three-phase) — it comes with a 5 m lead in the box, and a harvi wireless sensor is only needed where the clamp cannot be wired back. Built-in 6 mA DC detection plus PEN fault protection, so no earth rod; the Type A RCD goes upstream as with most units. Since July 2026 every zappi ships with "zapsafe", a dual-sensing PEN scheme myenergi introduced to cut the nuisance trips owners complained about on earlier firmware. Wi-Fi and Ethernet are built in, so the old hub is gone. Typical fit £400–£600. Full walkthrough in our installation guide.

Specification

Max Power Output: 7kW single-phase / 22kW three-phase (multiphase unit)
Cable Length: 6.5 metres (tethered version)

Dimensions: 438mm × 282mm × 122mm
Weight: 3.0 kg untethered / 5.5 kg tethered (single-phase)
IP Rating: IP65 + IK10
Protection: 6mA DC detection and zapsafe PEN fault protection built in; Type A RCD upstream
Display: Backlit LCD with buttons, PIN lock
Certification: OLEV/OZEV approved (all variants), UK Smart Charge Point Regulations

Tariff compatibility

What it costs to run.

Strong. Octopus Intelligent Go supports a zappi-side integration on every zappi from firmware V3 — the charger sits in Eco+ so solar diversion keeps working during the day while Octopus schedules the overnight slots, which the vehicle-API route cannot do. OVO Charge Anytime requires a 2.1 or GLO on firmware v5.733+ and a grid CT. Octopus Agile is handled natively: set a maximum price and plug-in window in the myenergi account and the zappi writes its own boost timer each afternoon. E.ON Next Drive names the zappi for its charger-led Smart route. No documented British Gas or EDF link — those run on the timer. Detail in our smart-tariff chargers guide.

Price

What you actually pay.

The unit is currently £684. £400–£600 is the working installation range, putting a typical installed total at £1,084–£1,284. 7 kW tethered 6.5 m (ZAPPI-2H07TB-G) at a trade retailer; untethered £663. myenergi's own store charges £799 tethered / £779 untethered; 22 kW from £833.

Five-year total

£1,898

Charger, installation, and five years of electricity on Octopus Agile, at 10,000 miles a year.

Less £500 if you qualify for the OZEV grant.

Against the field

How it compares.

Against the zappi GLO: same solar brain, same tariff links, same 6.5 m cable; the 2.1 adds the screen, classic Eco mode, Min Green Level, Ethernet, 22 kW and white, for £85. If you will never touch a setting on the wall, buy the GLO. Against the Ohme Home Pro: the Ohme still gets the extra Intelligent Go slots and is cheaper; the zappi is the better solar charger by a distance. Against the Hypervolt Home 3 Pro: the Hypervolt is tougher and better-looking; its solar mode is a CT-clamp add-on next to the zappi's three modes.
