What stands out
Main limitation
The installed range is an estimate. The source date above is separate from the editorial review date.
The charger you buy because you have solar panels. In Eco+ mode, the Zappi runs the car entirely on surplus solar — whatever your panels produce above household load goes to the battery, and nothing else does. Free miles while the sun's out. Eco mode softens the rule, topping up from the grid when solar dips. Fast mode ignores solar altogether and pulls full power like any other charger. No other unit here handles surplus solar with this much control.
The rest of the story is the myenergi ecosystem. Pair the Zappi with an eddi to divert spare solar into the hot-water tank, or a libbi battery to store daytime solar for overnight car charging. At £599, it is no longer one of the expensive chargers here, but without solar that premium still buys nothing the Tesla Wall Connector or Ohme Home Pro don't already deliver for less.
Best for: Solar households. The bigger the array, the better the fit. No solar? The Tesla or Ohme is probably your charger.
Installation
Fitting the myenergi Zappi GLO.
Larger than the Ohme or Tesla at 5.4 kg, 439 × 282 × 130 mm, but straightforward on a dedicated 32A circuit. For Eco and Eco+ to work, the installer fits a myenergi CT clamp on the meter tails — it reads your home's import and export in real time. Accredited installers include it as standard; budget for it if your electrician is new to myenergi. Tethered 6.5-metre cable, or an untethered version if you'd rather bring your own. No built-in RCD or SPD; both get added at the consumer unit. IP65 — fully weatherproof. Full walkthrough in our install guide.

Tariff compatibility
What it costs to run.
Better than the myenergi app suggests. Octopus Intelligent Go, OVO Charge Anytime and EDF's Smart Charging add-on all schedule the zappi directly — you give the supplier a departure time and it decides when the car draws. Octopus Agile works differently, and it's worth being precise: no supplier controls a charger on Agile. The zappi reads the day-ahead prices Octopus publishes at 4pm and books the cheap half-hours itself, which gets to the same place by the other road. Fixed two-rate tariffs like Octopus Go are a window set once in the app. The right setup for most Zappi owners: Eco+ during daylight (free surplus solar), the tariff's cheap hours overnight (cheap grid). More on combining the two in our solar + EV charging guide.

Less £500 if you qualify for the OZEV grant.
Against the field
How it compares.
Against the Tesla Wall Connector: wins on solar, overkill without it. Against the Hypervolt Home 3 Pro: more sophisticated solar control; less polished on everything else. Against the Ohme Home Pro: better for solar, weaker on tariff automation. Head-to-heads: vs Hypervolt, vs GivEnergy, vs EO Mini Pro 3. Full pattern in our solar chargers guide.
What we loved
- PlusSurplus-solar diverting in three modes — Eco+ runs the car entirely from what the panels are generating
- PlusPlugs into the myenergi ecosystem: eddi for hot water, libbi for battery storage
- Plus22kW three-phase option if your property supports it
- PlusRFID access for up to 126 users — useful on shared driveways
- PlusAvailable tethered (6.5 m) or untethered
- PlusIP65 — fully weatherproof
- Plus35% lower embodied carbon than the previous Zappi 2.1
What we didn't
- Minus£599 unit-only — money wasted without solar panels to feed it
- MinusNo built-in 4G; Wi-Fi only
- MinusOn Intelligent Go the Ohme still negotiates extra off-peak slots the zappi doesn't get
- MinusThe on-unit screen from the old Zappi 2.1 is gone — everything happens in the app
