The myenergi zappi ZAPPI-2H22TW-G is a 22kW three-phase tethered EV charger in white with a 6.5m Type 2 cable. It is the fixed-cable three-phase zappi for sites where the charger should be ready to plug in without a separate lead. The 22kW rating is intended for 400V AC three-phase supplies and is vehicle dependent, so it suits workplaces, commercial buildings and three-phase homes with compatible EVs. The tethered format is especially useful for repeat users because the Type 2 plug remains at the charge point. The charger includes a graphical backlit LCD, front LED status indication, ECO, ECO+ and FAST modes, built-in Wi-Fi and Ethernet, dynamic load balancing and integrated 6mA DC residual current protection. For range context, place it under zappi EV chargers.

Where does the tethered 22kW model fit?

The tethered 22kW zappi is made for three-phase sites where users return to the same charger regularly. A fixed 6.5m Type 2 cable removes the need to carry a separate lead to the unit, so it suits staff parking, fleet return bays and homes where the EV parks in a consistent position. The trade-off is that cable storage must be planned properly.

The 22kW rating only delivers its benefit where both supply and vehicle support it. Many domestic vehicles do not accept 22kW AC, so the installer or buyer should confirm the vehicle onboard charger before selecting three-phase equipment. Where the vehicle is limited to 7kW or 11kW AC, the charger cannot force a higher charge rate.

Solar-aware charging on three-phase power

zappi can take power from the grid, solar, wind generation or a combination of sources, depending on system configuration and mode. FAST mode charges at the maximum available Mode 3 rate. ECO mode adjusts charging in response to site generation and consumption, limiting grid electricity while allowing charging to continue.

ECO+ mode can pause the charge when import exceeds the configured threshold and continue only when enough surplus power is available. This is particularly useful on three-phase sites where EV charging is one of several significant electrical loads. It lets the charger respond to the building rather than simply drawing hard whenever a vehicle is plugged in.

The myenergi app gives remote control and monitoring, while the front display gives local status and menu access. For households or businesses comparing tariff-led charging, the LAMPS EV tariff guide can sit alongside the product page as a supporting internal link.

Protection and supply design

For ZAPPI-2H22TW-G, the three-phase datasheet verifies 22kW rated power, 400V AC three-phase supply, 50Hz frequency and 32A maximum rated current. Integrated 6mA DC residual current protection is listed with RDC-DD characteristics to EN 62955. The installer must still design the upstream circuit, isolation and protection for the site.

Dynamic load balancing is available as an optional setting to limit current drawn from the unit supply or the grid. This is important where a three-phase charge point shares capacity with other loads, such as workshops, offices, HVAC equipment or commercial kitchens. Correct CT positioning and phase configuration are essential for useful load management.

The zappi enclosure is IP65 weatherproof and IK10 impact rated. It is designed for permanent indoor or outdoor mounting, with cable entry through rear, bottom or side positions. External installs should account for water ingress protection, cable support, impact risk and the parked vehicle’s plug position.

Display, connectivity and OCPP use

The screen-based zappi provides a graphical backlit LCD and a multicolour front LED, so users can check status at the charger. That can be important on shared or commercial sites, where the person plugging in may not be the account holder or installer. The display also differentiates this standard zappi from the screen-free GLO family.

Built-in Wi-Fi and Ethernet provide internet connectivity without a separate hub on later models. The myenergi user manual lists OCPP 1.6J support for later Wi-Fi zappi model codes, including the -G versions, through the myenergi gateway. A myenergi account, firmware update and correct vHub setup are required for that route.

Smart charging regulation features include setup wizard changes, automatic firmware checking, tamper detection and encrypted communication. zappi also supports pin-code lock, programmable timers and charge event logging. These features help the charger suit more than basic domestic plug-in use.

Choosing between 22kW zappi formats

Choose this tethered model where the same users need quick plug-in access and the 6.5m cable reaches the vehicle bay comfortably. Choose the white untethered zappi where different cable lengths, cleaner wall appearance or shared cable ownership matter more.

Black variants are available where the charger needs to sit against darker posts, cladding or brickwork. The black tethered zappi keeps the same fixed-cable format with a different finish. For properties without three-phase supply, a 7kW single-phase model should be considered instead.
