Teltonika TeltoCharge 7.4kW Single Phase Home EV Charger

Teltonika TeltoCharge 7.4kW Home EV Charger — Overview

The Teltonika TeltoCharge is a 7.4kW single-phase Mode 3 electric vehicle charger for residential and light commercial use in South Africa. Combining robust hardware with smart charging software, the TeltoCharge delivers up to 32A of regulated AC charge current through a standard Type 2 socket — the universal EV charging connector for all vehicles sold in South Africa. Adjustable charge current from 6A to 32A enables load management, solar self-consumption optimisation, and dynamic current limiting.

Charging Speed: What to Expect in South Africa

At maximum 7.4kW output, the TeltoCharge adds approximately 35–40km of EV range per hour of charging, depending on vehicle battery size and efficiency. A 40kWh battery (Nissan Leaf 40kWh) charges from empty to 80% in approximately 4.5 hours. A 77kWh battery (VW ID.4) takes approximately 9 hours for a full charge — ideal for overnight charging at home. Charging at reduced currents (16A / 3.7kW) doubles charging time but reduces peak demand on your home’s electrical installation and can be integrated with solar self-consumption management.

Smart Charging Features

The TeltoCharge’s built-in Wi-Fi and OCPP 1.6J protocol compliance enable integration with home energy management systems and EV charge management platforms. Time-of-use scheduling allows the charger to start automatically during off-peak Eskom tariff periods, reducing electricity costs. Dynamic current adjustment allows a solar inverter or energy management system to modulate charge current in real time based on available solar generation, maximising solar self-consumption during daylight hours.

Installation Requirements for South Africa

The TeltoCharge requires a dedicated 40A single-phase circuit with a 30mA earth leakage protection device (RCCB) and a suitably rated overcurrent breaker. Installation must be carried out by a registered electrician in accordance with SANS 10142-1 and the latest Eskom or municipal distribution code requirements. An electrical Certificate of Compliance (CoC) is required. The unit is wall-mounted and requires a conduit or surface cable entry for the supply cable.

EV Compatibility

The TeltoCharge Type 2 socket is compatible with all electric vehicles sold in South Africa that use Type 2 onboard charging, including BMW i3, BMW iX, Nissan Leaf, Nissan Ariya, Volvo XC40 Recharge, Volvo C40, Volkswagen ID.3, Volkswagen ID.4, Hyundai Ioniq 5, Kia EV6, and Mini Electric. A Type 2 to Type 2 charging cable (Mode 3, 32A rated) is required and sold separately.

Frequently Asked Questions

Does the TeltoCharge work with all electric vehicles in South Africa?
The TeltoCharge has a Type 2 socket compatible with all EVs sold in South Africa that support AC Type 2 charging. Tesla vehicles require a Type 2 to Tesla adapter. CHAdeMO or CCS DC fast charging is not supported — the TeltoCharge is an AC Mode 3 charger only.

Can the TeltoCharge be connected to solar panels?
Yes, indirectly. When paired with an energy management system that supports OCPP or dynamic current control, the TeltoCharge can be instructed to reduce or increase charge current based on available solar generation, enabling solar-powered EV charging with minimal grid import.

Is the TeltoCharge approved for outdoor installation in South Africa?
Yes. The TeltoCharge is IP54 rated, meaning it is protected against dust ingress and water splashing from any direction. It is suitable for covered outdoor installation such as a carport or garage wall. Avoid installation in direct weather exposure without additional shelter.

What circuit protection is required for the TeltoCharge?
A dedicated 40A single-phase circuit is required with a Type A or Type B 30mA RCCB (earth leakage breaker) and a 40A or 32A MCB overcurrent breaker. Your registered electrician will specify the correct protection devices based on your installation.
