What Is the myenergi zappi 22kW Untethered Charger?

The myenergi zappi 22kW Three-Phase Untethered Black EV Charger (SKU ZAPPI-2H22UB-G) provides an intelligent, eco-smart charging solution for residential homes and workplaces with three-phase power supplies. Housed in a robust black polycarbonate enclosure, this charger is famous for its advanced solar diversion capabilities. It allows owners to maximize their self-consumption of green energy generated by wind or solar PV arrays. By operating at up to 22kW, it provides high-speed AC charging for vehicles capable of three-phase charging, while remaining backward compatible with standard single-phase cars. The untethered design features a clean Type 2 socket, offering flexibility for users with different charging cables. This system makes it easy to integrate vehicle charging with complete home microgeneration plants.

zappi 22kW Solar Matching and Harvi Sensor

The defining feature of the zappi is its three distinct charging modes: ECO, ECO+, and FAST. In ECO+ mode, charging pauses if grid import exceeds user-defined thresholds, resuming only when there is surplus local generation, enabling 100% free, green charging. The unit features built-in Wi-Fi and Ethernet ports, allowing direct connection to the internet for remote control and firmware updates. It also includes an eSense input for economy tariff detection, enabling the charger to prioritize cheap overnight grid rates. The front of the charger features a graphical backlit LCD screen and a multi-color LED indicator that reflects the current charging status. A pin-code lock function is built-in to prevent unauthorized setting changes or charging cycles.

Installing the zappi 22kW On Site

This charger is rated IP65 weatherproof and IK10 impact resistant, making it suitable for permanent installation in both indoor and outdoor locations. The physical enclosure measures 439mm high, 282mm wide, and 122mm deep. It has a standby power consumption of just 3W, ensuring energy efficiency when not in use. Electricians can route cables from the rear, bottom, or sides of the enclosure, adapting to the specific wiring path of the building. The unit is designed to operate in temperatures ranging from -25°C to +40°C, provided it is mounted out of direct sunlight. A secure, flat mounting base is critical to ensure proper seal compression.

Wiring and CT Clamp Setup for the zappi 22kW

Installers must connect the supply wiring to the heavy-duty internal terminal blocks, which support standard three-phase connections up to 32A. The unit features built-in PME fault protection, meaning an external earth rod is not required, simplifying the installation and reducing onsite labor. For solar matching and active load balancing, install the supplied grid CT clamps around the main incoming conductors. The CT sensors support a maximum primary current of 100A and accept cable diameters up to 16mm. If running physical data cables is impractical, the unit can integrate with the wireless Harvi sensor. Upstream circuit protection should consist of a dedicated three-phase circuit breaker and appropriate RCD protection conforming to current regulations.

zappi 22kW Handover and App Setup

After mounting and wiring the unit, guide the customer through the initial configuration using the graphical LCD display and the front control buttons. Show them how to set a secure PIN code to prevent unauthorized access and how to connect the charger to their home Wi-Fi network. Demonstrate how to switch between ECO, ECO+, and FAST modes, and explain the grid sensor readings. Ensure the customer downloads the myenergi app to monitor their charging history and configure smart schedules. Record the serial number in the handover pack for warranty registration and future service reference.

Common questions

Does the untethered zappi include a charging cable?

No, this model features a universal Type 2 socket. Users must connect their own separate Type 2 cable to charge their vehicle.

What is the purpose of the Harvi sensor?

The Harvi is an optional wireless energy sensor that transmits CT readings to the zappi wirelessly, avoiding the need to run long data cables.

Can this charger be installed on a single-phase supply?

Yes, while rated at 22kW three-phase, the zappi can be configured by the installer to run on a standard 7kW single-phase supply if required.

How does ECO+ mode handle intermittent sunshine?

In ECO+ mode, charging will temporarily pause if the surplus generated solar power drops below the minimum 1.4kW threshold, and will automatically resume once generation increases.

What is the CT clamp's maximum sensing current?

The supplied CT sensors support a maximum primary current of 100A, with cable diameters up to 16mm.

zappi 22kW Untethered vs Tethered vs 7kW

The myenergi zappi 22kW Untethered Black is perfect for untethered three-phase setups. If you prefer a tethered cable, the myenergi zappi 22kW Tethered Black comes pre-installed with a 6.5m lead. For single-phase only installations, the Zappi 7kW Untethered Black offers the same solar-matching technology at a lower price point. You can also integrate it with the myenergi eddi Power Diverter for complete home energy management.
