Zaptec Go 7.4kW Smart EV Charger — UK Version with Integrated PEN Fault Protection, Type 2, Wi-Fi + 4G

Why the Zaptec Go?

Connectivity and Smart Features

The Zaptec Go connects via Wi-Fi 2.4GHz (802.11 b/g/n) and 4G LTE-M, with Bluetooth Low Energy (BLE 4.2) for local pairing and setup. Both Wi-Fi and 4G are active simultaneously — the charger uses whichever connection is strongest, providing a resilient, always-online setup that doesn't depend on your home broadband. The 4G LTE-M connection is provided free by Zaptec for the entire lifetime of the charger, with no SIM card to insert and no monthly data charges.

All smart features are managed through the Zaptec App (iOS and Android), which provides:

• Start/stop charging remotely from anywhere
• Live charging status and session monitoring
• Full charging history and energy usage data (~3% accuracy via integrated energy meter)
• Manual charge scheduling — set charging windows to align with off-peak tariff times
• Eco Mode — automated scheduling using Nord Pool electricity price data (requires variable/dynamic tariff)
• Cable lock control — permanently lock the Type 2 cable to the charger via the app
• RFID tag management — add, remove, and manage RFID access cards and fobs
• Access sharing — grant charging access to other users (family, fleet drivers, guests)
• Push notifications for charging events, completed sessions, and fault alerts
• Remote firmware update management

The Zaptec Portal provides a cloud-based management interface for multi-charger environments — monitoring all chargers in real time, viewing per-unit energy consumption breakdowns, and managing user access across a portfolio of locations. Particularly relevant for fleet operators, housing developers, and commercial property managers.

For third-party integration, the Zaptec Go supports OCPP 1.6J cloud-to-cloud communication, plus REST API and Webhooks for custom software integration. Documentation is available at zaptec.com/ocpp.

Eco Mode — Automated Cheap-Rate Charging

Eco Mode uses historical electricity price data from the Nord Pool market to automatically identify the cheapest charging windows and schedule charging accordingly. In Eco Mode, you simply plug in your vehicle and activate the mode — the Zaptec Go determines when to charge based on price data, with options to set a departure time and minimum energy required. This means the vehicle will be charged to the required level in time for departure, using the cheapest electricity available overnight. Eco Mode works best with variable or dynamic electricity tariffs (such as Octopus Agile or similar) where prices genuinely vary hour-by-hour. For single flat-rate tariffs, manual scheduling to the off-peak window is the more effective approach.

Zaptec Sense — Optional Load Balancing

The Zaptec Go is compatible with Zaptec Sense, an optional energy monitoring unit fitted in the consumer unit that measures total household electricity consumption in real time. When Zaptec Sense is installed, the Zaptec Go automatically adjusts its charging speed based on the available headroom in the property's total electrical supply — preventing the main fuse from tripping when high household loads (electric ovens, showers, heat pumps) coincide with EV charging. Zaptec Sense is available separately for 1-phase, 3-phase 150A, and 3-phase 600A installations.

LED Status Ring — At-a-Glance Charger Status

The Zaptec Go has a distinctive RGBW LED ring positioned directly above the Type 2 socket. The LED provides instant at-a-glance status information:

Colour Options — One Charger, Six Colours

The Zaptec Go body and colour fascia are available in six colours. The core charger unit is the same across all colours; colour variant part numbers are listed in the product header comment above. All colours are finished in a matte UV-resistant coating suited for outdoor installation.

Frequently Asked Questions

PEN Fault Protection — Technical Note

This UK model (serial prefix ZGBxxxxxx) includes integrated open PEN fault protection as standard, complying with BS 7671:2018 Amendment 1:2020 clause 722.411.4.1 (iv) — the legal requirement for outdoor EV chargers on PME (Protective Multiple Earth) supplies. No external protection device (GARO, Matte:e, etc.) is needed. The charger also includes an integrated RDC-DD 6mA per IEC 62955, so no Type B RCD is required in the consumer unit — only a standard 30mA Type A RCD and max 40A circuit breaker.

The protection continuously monitors line-to-neutral voltage and disconnects the vehicle if it detects a fault (above 253V or below 207V rms for more than 5 seconds). The LED ring turns red, charging stops, and the Zaptec app shows a notification. Once stable voltage returns for 30 seconds, the charger resumes automatically. If a PEN fault is confirmed, call your DNO on 105. An independent test report is available from Zaptec on request.
