The ZAPPI-2H22TB-G is a 22kW three-phase tethered Type 2 EV charger in black for faster AC charging on 400V supplies.

Built for sites with a three-phase supply, this version of zappi suits households, estates and smaller premises that want higher AC charging capacity, smart energy control and the convenience of a fixed lead. The tethered black model combines a permanently attached 6.5m Type 2 cable with built-in WiFi, Ethernet, current sensing and the current UK smart charge point feature set used on the -G range. It is a practical fit where the vehicle usually parks in the same place and the user wants the quickest possible daily routine without handling a loose cable at every session. Black and grey trim also gives the charger a quieter visual fit on darker brick, cladding, fencing and anthracite details, which matters more on a tethered unit because the cable remains part of the outside appearance between charges.

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

22kW three-phase charging with a 6.5m lead

A 22kW AC charger only makes sense when the supply and vehicle can use it, but where those conditions are met it gives much stronger charging performance than a 7kW unit. The three-phase tethered zappi is designed for that setting. A permanently attached 6.5m Type 2 cable keeps the charger ready to use at all times, which is valuable on regular overnight charging, shared family use and sites where the car returns to the same bay each day. There is no separate lead to unpack from the boot, no cable to leave damp in the car after bad weather and no question about whether the right lead is available. That makes the fixed-cable format especially useful on busy daily-use installations where convenience matters just as much as the electrical rating.

Do all EVs take 22kW AC?

Not every vehicle can use the full 22kW available from a three-phase charger, and that is one of the most important buying points to explain clearly. The charger can offer up to 22kW on a suitable 400V three-phase supply, but the actual rate still depends on the onboard AC charger in the vehicle. Some EVs can accept 22kW AC, some are limited to 11kW on three-phase, and others take less. That does not make the charger the wrong choice. It means the site is being equipped with a higher-capacity charger that can support current vehicles properly and still suit future vehicle changes. On homes or premises with multiple EVs over time, that future flexibility can matter more than the charging rate of the first car using it.

Solar charging, tariffs and battery-aware logic

zappi’s real advantage is the way it manages energy rather than simply its headline power. ECO mode blends imported electricity with available self-generated energy and adjusts charge current continuously in response to what the property is producing and consuming. ECO+ takes that further by prioritising genuine surplus generation and pausing when there is not enough export available, which is useful on sites trying to raise solar self-consumption rather than just charge quickly. FAST mode turns the charger into a conventional full-rate AC unit when the priority is replenishing the vehicle as quickly as the installation allows. The platform is also designed to work with broader home energy arrangements, so solar generation, battery storage and time-of-use tariffs can all influence when and how charging takes place.

WiFi, Ethernet and charge logs as standard

Built-in connectivity is one of the reasons zappi remains commercially useful after installation rather than only on day one. WiFi gives a straightforward route for sites with dependable local wireless coverage, while Ethernet offers a hard-wired alternative where more stable communications are preferred. Once online, the charger can be monitored and adjusted in the myenergi app for charge modes, timing and day-to-day control. Charge and event logging, remote access and automatic firmware checking make the system easier to manage over time, especially on installations where electricity cost, solar generation or fleet usage patterns change. For buyers comparing 22kW chargers, that matters because high output on its own is only one part of the decision. Long-term visibility and usable control are what make the charger easier to live with.

Three-phase CT sensors and current limiting

Three-phase zappi models are supplied with the clip-on grid sensors needed for a proper three-phase current-sensing setup, which means a CT needs to be fitted around each live tail. That sensing arrangement is central to how zappi manages solar charging and load-aware behaviour. It also supports current limiting and load balancing options that can help protect the site from drawing more than the installation should allow. Device limits can be set where the circuit capacity is restricted, and the three-phase platform also includes settings such as neutral current limiting for installations that need that level of control. For the installer, that means the charger is not simply a 22kW output box. It is a more considered three-phase charging platform that can be tuned to the actual supply conditions on site.

PEN protection, 6mA DC and upstream Type A

Protection detail matters on any serious EV charging project, especially on three-phase supplies where the buyer is often more technically aware. 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 parts of the charger’s internal protection package, but they do not remove the need for correct upstream circuit design. myenergi’s installation material also makes clear that an additional upstream Type A RCD or RCBO is required. In practice, that gives electricians a charger with key EV-specific protective functions already integrated, while still leaving the wider installation to be designed in line with current regulations and the earthing arrangement actually present on site.

Black charger for darker exteriors

Colour is not only decorative on an EV charger that lives permanently on an outside wall. The black and grey housing on this version makes practical sense on dark brick, darker render, timber cladding, metal fencing and anthracite trims because the unit tends to stand out less once installed. On a tethered charger, that matters even more because the cable and plug remain visible between sessions. A darker case and matching plug reduce how visually dominant the charger feels on those elevations. The enclosure is rated IP65 and IK10, so the finish is part of a body designed for permanent outdoor exposure rather than a sheltered indoor-only application. For prominent wall positions, colour choice can change how acceptable the finished install feels to the homeowner long after the electrical work is complete.

Related myenergi add-ons and buying choices

The charger can operate on its own, but it also fits naturally into the wider myenergi ecosystem. Sites where CT wiring is awkward often pair zappi with the myenergi harvi to avoid difficult cable routes for sensing. Homes already diverting surplus generation to hot water can add the myenergi eddi so vehicle charging and domestic diversion sit within the same control environment. Buyers comparing the broader zappi range should treat this model as the fixed-cable option for three-phase supplies. The key reason to choose it is not simply that it is black or tethered. It is that the site has three-phase capacity, the user wants a lead always ready to go, and the installation will benefit from the charger’s energy-aware control features.

Choosing between the 22kW zappi variants

Choose the black tethered version when the property has a 400V three-phase supply, the vehicle usually parks in a predictable position and a permanently attached 6.5m cable suits the layout. That combination makes the charger fast to use and visually quieter on darker surroundings. The white tethered version keeps the same charging format and electrical capability but suits pale render, light brick and lighter garage surrounds better. An untethered 22kW zappi is more suitable when the owner wants a cleaner front between charges, prefers to use the vehicle’s own cable or wants flexibility around lead length and storage. Across all four variants, the core difference is less about energy logic and more about cable handling, supply type and how the charger will sit on the building after installation.
