Mobile connectivity for a single-phase home charger

The NRG Charge Velox 7kW 4G combines the domestic single-phase charger format with an added mobile-network connection. It is designed for a suitable 230V supply, operates at up to 32A and uses an untethered Type 2 socket. Its main reason to exist alongside the standard Velox 7kW is connectivity: this version adds 4G where the installation should not depend only on local Wi-Fi or a wired LAN route.

That can be useful at a detached garage, an external parking area at the edge of home Wi-Fi coverage or a property where extending the local network would be awkward. Mobile connectivity is not a substitute for checking coverage and service conditions. Confirm the current SIM, activation, data term and renewal arrangement before ordering, because those commercial details determine the long-term value of the 4G hardware.

When to choose 4G instead of the standard Velox 7kW

Choose between the two 7kW models by looking at the mounting position rather than assuming that more connectivity is always better. The standard unit is the simpler route where reliable Wi-Fi reaches the charger or a LAN cable can be installed. The 4G unit is more relevant where a mobile connection provides a practical backup or primary route.

Do not order by the `4G` label alone. Verify signal where the charger will be mounted and understand who provides the service, how it is activated and what happens at the end of any included period.

A Type 2 socket keeps the cable removable

This is an untethered charger, so it does not have a vehicle lead fixed permanently to the enclosure. A separate Mode 3 Type 2 charging cable connects the socket to the car. The cable can be removed after charging, leaving the compact charger body on the wall without a coiled lead.

Measure from the intended wall position to the vehicle inlet before selecting a cable. Include the normal parking direction and avoid a route that stretches the lead or crosses a doorway or footpath. Browse EV charging cables after the installer or project designer has confirmed the required rating and reach.

App control, two RFID fobs and open access mode

NRG documents list three ways to start a session. App mode supports remote start/stop, status and supported scheduling through the NRG consumer application. RFID mode requires an approved key fob and is useful where the charger is physically accessible to other people. Two RFID key-fob tags are documented as included. Plug-and-charge removes the separate authorisation step for a private location.

These control modes should not be confused with direct compatibility with a particular electricity tariff. A charging schedule can be arranged through the supported charger or vehicle controls, but any named tariff's current eligibility and integration route must be checked with the provider.

The included sensor supports dynamic load balancing

The 7kW 4G model uses the same single-phase load-management principle as the standard 7kW unit. One grid current sensor is documented for the 7kW pack. Correctly installed and configured, it allows the charger to respond to the property's wider demand rather than assuming that its maximum output is always available.

This feature helps manage the charger alongside other substantial household loads, but it does not increase the incoming supply. The electrician remains responsible for the supply assessment, main fuse limit, circuit design, earthing, protective arrangement, cable route, sensor polarity, testing and configured charging limit.

Solar monitoring is an additional installation choice

Velox can use a second current sensor to monitor the solar inverter output. That is separate from the grid sensor used for load balancing. With the required hardware and configuration, the charger can respond to PV generation and can combine a solar contribution with a configured amount of grid power.

Include the extra sensor and its wiring route in the installation design. The available documents do not establish universal coordination with every battery-storage system, so a property with both solar and a battery needs its intended power flows reviewed before commissioning.

Five finishes without five duplicated chargers

The complete charger is supplied in Black. LAMPS also plans to stock Anthracite Grey, Pure White, Sapphire Blue and Sage Green fascia covers. These are separate visible cover components, not separate electrical charger models.

Use the Velox front fascia page to select an alternative finish. Confirm whether the cover is being ordered separately or bundled with the charger, and ensure the basket line cannot be mistaken for a complete charge point.

Modular construction and network planning

The enclosure separates into a passive wiring backbox, the main electronic body and the click-on fascia. This lets the installer plan power, current-sensor and communications connections at the backbox before securing the charger body and selected cover.

For the 4G version, commissioning must include both the electrical work and the intended communications route. Bluetooth is documented for configuration, while ongoing connected operation can use the available network interfaces. The charger must be installed and commissioned by qualified and competent personnel; the modular structure does not make it a DIY product.

Specification

Common questions

What does 4G add to the Velox 7kW?

It adds a mobile-network connection to the model's Wi-Fi and LAN options. This can help where the charger position has weak home-network coverage, but mobile signal and the current service/SIM terms still need to be checked.

Can the 7kW 4G charger work through Wi-Fi?

Yes. The 4G version does not remove Wi-Fi or LAN. The installer should commission the connection route that suits the property and confirm how the mobile service is intended to operate.

Is a Type 2 cable supplied?

No vehicle charging cable is included in the cleared core list. This is an untethered Type 2 socketed charger, so a separate compatible Mode 3 cable is needed.

Does the charger include load balancing?

NRG's 7kW documentation lists one grid current sensor as standard. The sensor and property limit must be installed and configured correctly by the electrician.

Can I add a different coloured front?

Yes. LAMPS plans to stock Anthracite Grey, Pure White, Sapphire Blue and Sage Green fascia covers for compatible Velox units. They change the visible finish rather than the electrical specification.
