Andersen A3 vs myenergi Zappi

The Andersen A3 and the myenergi Zappi sit at the premium end of the home charger market, and both offer full solar diversion — sending surplus generation from your panels into the car instead of the grid. Both are grant eligible and both charge at 7kW on a single-phase supply. The split is simple — the A3 is the design purchase, the Zappi the flexible one — and the Zappi starts £216 cheaper.

Where the Andersen A3 wins

On the wall, it’s not close. The A3 hides its 5.5m cable behind a magnetic lid, so no lead drapes down your brickwork, and it comes in 247 colour and finish combinations, from 13 standard metals to Accoya wood and a custom palette service. The Zappi offers nothing comparable on finishes.

The warranty runs 7 years to the Zappi’s 3, though full on-site cover requires installation by Andersen or an approved affiliate. And on tariffs the A3 lists three integrations — Intelligent Octopus Go (native), OVO Charge Anytime and EDF GoElectric — where the Zappi lists only OVO Charge Anytime.

Where the myenergi Zappi wins

Price, first: £779 unit-only against £995, with installations starting at £800 against the A3’s £1,374 via Andersen.

Configuration, second. The A3 comes one way: 7kW, single-phase, tethered with a 5.5m lead. The Zappi comes tethered or untethered, 7kW single-phase or 22kW three-phase, so it fits more properties and more future plans.

Then the solar ecosystem. Both divert surplus solar, but the Zappi’s eco and eco+ modes are the class benchmark, and it doubles as the hub for myenergi’s home battery and immersion diverter. It also offers Ethernet alongside Wi-Fi, where the A3 relies on 2.4GHz Wi-Fi with no Ethernet or 4G fallback.

The deciding factors

Price. The unit gap is £216. Installed, Andersen quotes £1,374–£1,430, while Zappi jobs run £800–£1,500 depending on installer and cable run — so a straightforward Zappi install can undercut the A3 by £500 or more, but a difficult one won’t.

Warranty. Seven years against three. Four extra years of cover claws back a meaningful part of the A3’s premium — provided you use an Andersen or approved-affiliate installer to qualify for full on-site support.

Solar and tariff fit. With panels and a myenergi battery, or plans for either, the Zappi’s ecosystem is the stronger platform. On Intelligent Octopus Go or EDF GoElectric, only the A3 lists an integration. On OVO Charge Anytime, both work — so decide on looks, configuration and price instead.

Whichever you choose, installation cost varies more by property than by charger, so get quotes before you commit: find a home charger installer.
