The ZAPPI-2H22TW-G is a 22kW three-phase tethered Type 2 EV charger in white for faster AC charging on 400V supplies.

Designed for properties with three-phase power, this version of zappi suits buyers who want the speed potential of 22kW AC charging, a fixed charging lead and a lighter-looking installation on pale walls. The tethered white model keeps the same core energy and connectivity platform as the other current 22kW zappi variants, including built-in WiFi, Ethernet, clip-on grid sensing, ECO, ECO+ and FAST modes, and the current -G smart charge point compliance package. What changes here is the cable format and finish. A permanently attached 6.5m Type 2 lead makes everyday charging quicker and simpler, while the white and grey housing sits more naturally on render, white garage doors and light masonry where a darker charger can feel more visually prominent than the owner wants.

• Best suited to three-phase properties that want a fixed white charger

White 22kW charger with a fixed Type 2 lead

The case for choosing the tethered white version is straightforward. It gives the user a permanently attached 6.5m lead so the charger is always ready to use, while keeping the housing visually lighter on pale exteriors. That combination suits properties where the charger is mounted on visible render, painted masonry or light brick and the owner wants the installation to feel more integrated with the building. The tethered format also simplifies everyday charging because there is no separate lead to retrieve from the boot, uncoil, reconnect and repack after each session. On homes with one main EV and a familiar parking pattern, that small difference quickly becomes one of the most appreciated parts of the installation. The 6.5m cable length also helps on wider driveways and side parking positions where a shorter lead may feel restrictive.

Three-phase charging for the right supply

A 22kW charger is only appropriate when the property has a suitable 400V three-phase supply, so this is not the universal option for every home. Where that supply is available, though, the charger gives much more AC charging headroom than a 7kW unit. That can benefit three-phase homes, higher-spec domestic projects and some smaller workplace or mixed-use sites. The practical point buyers need to understand is that the charger can offer up to 22kW, but the vehicle still decides what it can actually accept from AC charging. Some EVs take 22kW AC, others take 11kW, and some remain lower. For that reason, this model should be chosen for the capability of the site and the likely vehicle mix over time, not only the rating of the current car. It gives the installation room to support faster-capable vehicles later.

ECO, ECO+ and FAST with solar and tariff logic

zappi remains different from a basic three-phase charger because it actively manages where charge energy comes from. ECO mode continuously adjusts charge current to blend imported power with any surplus generation available on site. ECO+ is more selective and will only continue charging when enough genuine surplus generation is available, pausing if that surplus drops below the minimum required by the vehicle. FAST ignores that optimisation and delivers full-rate AC charging from whatever source is available, which is useful when time matters more than self-consumption. That mix of modes gives the charger genuine range in practice. It can behave like a straightforward 22kW charger, a solar-aware charger or a charger scheduled around cheaper time-of-use tariff periods, depending on what the property and user actually need.

App control, Ethernet and firmware support

The current zappi platform includes the connectivity most buyers now expect without demanding extra hardware. Built-in WiFi supports standard domestic installations where the charger is within reliable router range, and Ethernet offers a stable wired route where signal strength is less predictable or where the installer wants a more fixed communications path. Through the myenergi app, users can change charge modes, schedule sessions and review charging activity remotely. Charge and event logging adds operational visibility, while automatic firmware checking helps keep the charger current as the wider smart charging environment develops. For a 22kW charger, that matters because higher-power AC charging is often installed on more considered projects where the owner expects better control, more transparency and a charger that still feels manageable once it becomes part of the property’s everyday routine.

Three CT sensors and current-aware installation

Three-phase zappi models are supplied with the sensing hardware needed for three-phase monitoring, which means a CT sensor must be fitted around each live tail. That measurement layer is fundamental to the charger’s solar-aware and load-aware behaviour. It is what allows the unit to respond to imported power, exported power and wider site demand instead of charging blindly at one fixed rate. The three-phase platform also supports current limiting and load balancing functions so the charger can be configured to respect the actual capacity available on site. That is particularly useful where the supply is three-phase but still needs careful management because of other building loads. Buyers often focus on the 22kW headline, but the real value here is that the charger can use that three-phase supply intelligently rather than simply drawing at maximum current whenever a vehicle is connected.

Protection and upstream device requirements

zappi includes built-in protection against loss of the PEN conductor and built-in 6mA DC residual current protection in accordance with EN 62955. Those are important details because they address two of the key protection areas that EV charger buyers and installers actively look for. At the same time, the installation manual makes clear that an upstream Type A RCD or RCBO is still required. That point matters because built-in EV charger protection does not remove the need for proper upstream design and coordination. On a three-phase installation, that wider circuit design becomes even more important because the charger is part of a higher-capacity supply arrangement. In practice, the charger arrives with core EV-specific protective functions in place, but the installer still needs to design the full circuit to match local regulations and the earthing system on site.

White EV charger for render and pale brick

The white and grey housing is the visual reason to choose this version over the black equivalent. On pale render, white-painted walls, cream brick and lighter garage surrounds, a white charger generally feels less heavy once mounted. That is especially relevant on a tethered unit because the cable and plug stay visible between charging sessions and form a more obvious part of the external finish. A darker charger can work perfectly well electrically, but the overall installation may feel more visually pronounced than the owner wants on a front or side elevation. With IP65 weather protection and IK10 impact resistance, the enclosure is designed for permanent outdoor use as well as indoor mounting, so finish choice is part of a real installation decision rather than a showroom-only preference. On lighter exteriors, the white case often gives a neater-looking result.

Myenergi accessories and related choices

The charger works as a standalone unit, but it also fits logically into the broader myenergi range. Where a site makes wired CT routing awkward, the myenergi harvi can simplify the sensing side of the installation. Homes already diverting excess generation to hot water can add the myenergi eddi so charging and hot-water diversion sit within the same ecosystem. Buyers comparing the broader zappi family should view this model as the fixed-cable, lighter-finish option for three-phase sites. It suits users who want the convenience of a permanently attached lead and a charger body that blends better into pale walls, while still keeping the same core smart charging platform as the other 22kW versions.

Choosing between white, black and socketed

Choose the white tethered version when the building has a light exterior finish and the driver wants the fastest possible plug-in routine from a permanently attached lead. That is usually the right fit for pale render, white garage doors and predictable parking positions. The black tethered model keeps the same 22kW three-phase platform and fixed 6.5m lead but suits darker surroundings better. An untethered 22kW zappi is more suitable when the user wants a cable-free front between sessions, prefers to use a separate lead or expects cable length requirements to change later. Across the four 22kW variants, the fundamental decisions are supply type, lead preference and visual finish rather than changes to the core smart charging behaviour.
