Masterplug Smart EV Charger review

The Masterplug Smart EV Charger is a charger you have fitted at home to charge an electric car, and it can also use spare power from solar panels. It charges at 7.4 kW, the usual speed for a home charger: about 25 to 30 miles of range for every hour plugged in. It works with overnight EV tariffs that only need a timer, but it is not on the Octopus, E.ON Next or OVO smart tariff lists.

Is the Masterplug Smart EV Charger right for you?

The questions most people start with, answered from Masterplug's own documents.

How fast does it charge?

7.4 kW

About 25 to 30 miles of range for every hour plugged in, and about 10 to 11 hours for a full charge for most cars. There is no 22 kW version.

  • 7.4 kW single-phase

Is the Masterplug Smart EV Charger tethered or untethered?

Both

You can choose a fixed cable (5 m), or a socket where you plug in your own cable. Installers call a fixed cable "tethered" and a socket "untethered".

  • Fixed cable, 5 m
  • Socket for your own cable

Is the Masterplug Smart EV Charger compatible with Intelligent Octopus Go?

Not listed

Octopus does not list it as a charger, so Intelligent Octopus Go would need a car Octopus supports instead. E.ON Next and OVO do not list it either. It works with any overnight tariff that only needs a timer, such as EDF GoElectric.

  • OctopusNot listed
  • E.ON NextNot listed
  • OVONot listed

Can it charge from solar panels?

Yes

It can charge your car with spare power from your panels, instead of sending it back to the grid.

Does it work with all electric cars?

Type 2

It uses the Type 2 connector, which most electric cars sold in the UK use. Check the charging socket on your car, or ask your installer.

Does the Masterplug Smart EV Charger support V2H or V2G?

No

Masterplug does not publish vehicle-to-home (V2H) or vehicle-to-grid (V2G) support for it, so it charges the car only. Chargers with vehicle-to-grid hardware.

Can it stay connected without Wi-Fi?

No

It connects by Wi-Fi or a network cable, and has no mobile data. Check your Wi-Fi reaches the driveway, or ask about running a cable.

  • Wi-Fi
  • Network cable
  • Mobile data (4G)

Does the Masterplug Smart EV Charger need an earth rod?

Usually not

It has a built-in safety feature (Masterplug calls it PEN fault protection) that usually means no earth rod is needed. Your installer checks all of this first.

How long is the warranty?

3 years

3 years.

Masterplug Smart EV Charger features explained

Every feature, from Masterplug's datasheet, manual and product pages.

What is the Masterplug Smart EV Charger?

Masterplug, a brand of Luceco plc, sells a Mode 3 smart wall charger in socketed and 5 m tethered versions, in black or white. It charges at up to 7.4 kW on a single-phase supply and is controlled through the Sync Energy app; Sync Energy is another Luceco brand.

Charging power: 7.4 kW single-phase, no 22 kW version

The charger delivers up to 7.4 kW (32 A), configurable from 6 A to 32 A, on a 220 V to 240 V single-phase supply. There is no three-phase version. The rate your car charges at is also limited by its own onboard charger.

Tethered or untethered: the cable options

Four models are listed: socketed (EVCM3SS7B black, EVCM3SS7 W white) with a Type 2 auto-locking socket, and tethered (EVCM3ST7B black, EVCM3ST7 W white) with a 5 m Type 2 cable. The unit has integrated cable storage.

Solar charging

Masterplug says the charger supports solar charging with no additional cost or subscription. Its specification sheet describes auto solar charging in the Sync Energy app, and a load management clamp is supplied with the charger.

Smart charging with Octopus, E.ON Next and OVO

The Sync Energy app provides Tariff Sense, which schedules charging according to your tariff's rates, tracks costs in real time and lets you control the charger remotely.

On the energy suppliers' own lists (checked 4 October 2026), Masterplug is not listed by Octopus for Intelligent Octopus Go, by OVO for Charge Anytime, or by E.ON Next for Next Drive Smart.

Load balancing, earthing and installation

A load management clamp is supplied, supporting circuits up to 120 A. The specification sheet lists integrated PEN protection (earth disconnection) and states that an earth rod is not required; it supports TT, TN-C-S and PME earthing. Residual current protection is an integrated Type A RCD with 30 mA AC and 6 mA DC detection. Masterplug lists a 40 A MCB or 30 mA Type A RCBO for the consumer unit, depending on cable type and route.

App, Wi-Fi and connectivity

The charger connects over Wi-Fi (2.4 GHz) or Ethernet and supports OCPP 1.6J. Bluetooth is used for set-up through the installer app. It has an internal meter (2%, Class C equivalent) and supports an external RS485 Modbus meter, with an RGB LED and buzzer for status.

Size and dimensions: 304 x 236 x 129 mm

The charger measures 304 x 236 x 129 mm. The UV-resistant polycarbonate enclosure is rated IP65 and IK08 in the specification sheet and product page (Masterplug's EV landing page gives IP55), and operates from -25°C to +50°C with integrated thermal protection. Masterplug lists compliance with the Electric Vehicles (Smart Charge Points) Regulations 2021, including Schedule 1.

Warranty: 3 years

Masterplug gives a 3-year standard warranty on the charger.

Masterplug Smart EV Charger FAQs

How long does the Masterplug Smart EV Charger take to charge a car?
At 7.4 kW it adds about 25 to 30 miles of range an hour. A typical top-up of about 162 miles takes about 5h 21m, so it fits in a night. A full charge from empty takes about 10 to 11 hours for most cars. Your car's battery size changes this.
Do I need solar panels to use it?
No. It charges like any home charger without them. Using spare solar power is an extra for homes that have panels.

If you rent, or own a flat with private off-street parking, the EV chargepoint grant can cover 75% of the cost of buying and installing a chargepoint, up to £500. Check on GOV.UK (checked 4 October 2026). Homeowners in houses are not eligible.
