myenergi Zappi review

The myenergi zappi is the charger for homes with solar panels, a three-phase supply or an OVO tariff. Its Eco+ mode charges from surplus generation only, pausing rather than importing from the grid, and a CT clamp comes in the box. The price you pay for that is a higher bill than most rivals at independent installers, a three-year warranty and an owner-survey record that sits mid-table.

Price and what’s included

myenergi sells the current zappi 2.1 from £779 for the 7kW single-phase untethered version. Tethered and 22kW three-phase models cost more, as listed below. myenergi publishes no installed price — it sends buyers to its Product Champion installers for a free quote — but OVO Energy fits the zappi from £949 with a standard installation (up to 10m of cable, no groundworks), and independent installers list it at about £1,095 to £1,190.

Our price score uses OVO’s published figure, the lowest fitted price we found. Expect more from an independent installer, and see our installation cost guide for what pushes a quote up. Wiring regulations also require your installer to fit a separate surge protection device, because myenergi says the zappi’s built-in surge protection does not replace one. We found no Amazon UK listing for the charger itself.

Where to buy (prices seen on 10 October 2026, and they can change):

• myenergi direct: 7kW £779 untethered / £799 tethered; 22kW £833 / £865
• myenergi Product Champion installers: Free quote; installed price not published
• Electrical wholesalers (Yesss, CEF, Expert Electrical): Trade-listed; Yesss confirms 6.5m tethered, IP65; prices not captured

Smart features and tariffs

Solar is the headline. The zappi has three modes. Eco blends solar or wind with grid power and adjusts as generation changes. Eco+ uses surplus only and pauses when it would have to import. Fast ignores solar. The grid CT clamp must see all import and export. An optional wireless CT (harvi) is available. Our solar EV charging guide explains how the modes work in practice, and the CT clamp guide covers placement.

The zappi works with Intelligent Octopus Go: Octopus lists it as generally available. It also works with OVO Charge Anytime on the 2.1 and GLO, which Ohme no longer does. Other tariffs run through schedules. The CT clamp lets the charger adjust continuously to other loads, but one Australian retailer lists “no load management”, so treat balancing several chargers as unverified.

The app is the myenergi app, and the unit also has a front display and buttons. Current “H” models have built-in Wi-Fi and Ethernet and no hub is needed, though the zappi needs a 24-hour internet connection to operate and has no 4G. It slots into myenergi’s ecosystem (eddi, libbi battery, harvi). myenergi does not advertise OCPP.

Installation and safety

Built-in PEN fault protection means no earth rod. Be careful on the RCD, because myenergi’s wording has changed over time. The current installer FAQ describes a Type A function with 6mA DC leakage detection but still asks for a separate upstream 30mA Type A RCD. Older statements claimed a built-in 30mA Type A RCD, so check the manual for your unit. Our PEN fault and earthing guide explains the rules.

The install guide requires IP65 glands and trade listings give IP65 and IK10, though those figures are not on myenergi’s own page. The same goes for dimensions: a retailer lists the zappi at about 439 x 282 x 122mm, so it is large next to an Ohme or Wallbox. The warranty is three years as standard; What Car? says it can be extended to five, but we could not verify the terms or price. The zappi is made in the UK. Choose 7kW or 22kW according to your supply: most homes are single-phase, where 7.4kW is the ceiling.

What owners report

The evidence is at brand level. In the What Car? owner survey (published on a page sponsored by Pod), myenergi scored 3 out of 5 and tied for 5th of 11: installation 4, reliability 3, fault repairs 3. A fifth of owners reported a fault, 27% of complaints were unresolved and about half of problems ended in a replacement unit. Autotrader’s 2026 Drivers’ Choice awards named myenergi a runner-up for Best Home Charger, behind the Hypervolt.

Specific complaint data is thin. The one product-level note we found is from OVO, whose staff say Charge Anytime onboarding needs the latest firmware and a CT clamp fitted the right way round. We found no zappi-specific forum threads in our sources, so we cannot say more about connectivity or app problems than the survey does.

How it compares

The Hypervolt Home 3 Pro is the closest solar rival, with a better owner record and a tougher case but no three-phase option. The Ohme Home Pro is smaller and cheaper installed, with 4G and the most mature IOG integration, but it has no three-phase model.

Our verdict

We score the myenergi zappi 7.0 out of 10. It earns 9.0 on smart features, level with the Hypervolt, 6.6 on price (OVO fits it from £949 with a standard installation) and 6.0 on flexibility, but only 5.7 on reliability. If you generate solar power, have a three-phase supply or are with OVO, it is the best fit. If you are mainly chasing cheap overnight rates on IOG, an Ohme is cheaper and smaller; if you want the strongest owner record, choose the Hypervolt.
