## Masterplug Smart EV Charger features explained

### 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 installation

- **Supply:** Single-phase, up to 7.4 kW

1. **Survey.** An installer checks your supply, consumer unit, main fuse and earthing, and where the charger and its cable will go. Many do this from photos first.
2. **Notify the network operator (DNO).** Your installer tells your local network operator (DNO) about the charger, and applies first where the supply needs checking.
3. **Fit and test.** The charger goes on its own circuit and is tested. Ask for the supply sensor for solar charging to be fitted on the same visit.
4. **Connect it.** The installer connects the charger to Wi-Fi, Ethernet or Bluetooth and sets it up in the maker's app.
5. **Set up your tariff.** Set a charging schedule for your tariff's cheap hours. Smart tariffs that control the charger directly do not list it, but some work through a compatible car.

## Masterplug Smart EV Charger FAQs

### Which app does the Masterplug Smart EV Charger use?

The Sync Energy app. Masterplug and Sync Energy are both brands of Luceco plc, and the app provides auto solar charging and Tariff Sense rate-based scheduling.

### Can the Masterplug charger use solar power?

Masterplug says the charger supports solar charging with no additional cost or subscription, through auto solar charging in the Sync Energy app. A load management clamp is supplied.

### What is the IP rating of the Masterplug Smart EV Charger?

IP65, with an IK08 impact rating, according to Masterplug's specification sheet and product page. Masterplug's EV landing page lists IP55; the specification sheet is the more detailed document.

### Does the Masterplug charger need an earth rod?

Masterplug's specification sheet lists integrated PEN protection and says an earth rod is not required. It supports TT, TN-C-S and PME earthing.

### Which smart EV tariffs work with the Masterplug Smart EV Charger?

It is not on the Octopus, OVO or E.ON Next smart tariff charger lists (checked October 2026). Fixed-window EV tariffs, such as EDF GoElectric, E.ON Next Drive and Octopus Go, need only a timer on the charger or the car.

### Which chargers are similar to the Masterplug Smart EV Charger?

Andersen Quartz, Cord Zero and EO Mini Pro 3 share the most charger types with it (such as solar charging, cable type and smart tariff listings). They are listed by how many types they share, then A to Z; this is not a ranking. Compare any two side by side on our compare page.

### 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 the Masterplug Smart EV Charger, so it charges the car only.

### How much does the Masterplug Smart EV Charger cost?

We do not list prices, because they change often and most people buy a charger fitted, so the price depends on the installer and your home. Ask two or three installers for a fitted price for the Masterplug Smart EV Charger by name. 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.

## EV charger terms explained

- **Tethered charger:** A charger with the charging cable fixed to the unit.
- **Untethered (socket) charger:** A charger with a Type 2 socket instead of a fixed cable, so you plug in your own charging cable.
- **Type 2:** The standard connector for AC charging on cars sold in the UK and Europe.
- **Single-phase and three-phase:** Most UK homes have a single-phase supply, which limits a home charger to about 7 kW (32 A). A 22 kW charger needs a three-phase supply, and the car must accept 22 kW on AC to use it.
- **kW and kWh:** kW is charging power; kWh is energy. A 7 kW charger adds up to about 7 kWh an hour, less charging losses.
- **Solar charging:** A mode that varies the charging current to follow surplus solar generation, measured by a sensor on your supply, so the car uses power you would otherwise export.
- **CT clamp:** A current sensor clipped around a supply cable. It tells the charger how much power the home is importing or exporting.
- **Load management:** The charger lowers its charging current when the rest of the home is using a lot of power, so the main fuse is not overloaded.
- **PEN fault protection:** Protection that disconnects the charger if the combined neutral and earth (PEN) conductor in the supply fails. Chargers with it built in can usually be installed without an earth rod; your installer confirms what your supply needs.
- **RCD and RCBO:** Devices that cut the power if current leaks to earth. Some chargers need a Type A RCD or RCBO fitted at the consumer unit; the maker's installation notes say which.
- **OCPP:** Open Charge Point Protocol, an open standard that lets a charger connect to a third-party management platform as well as the maker's app.
- **RFID:** A card or key fob reader on the charger, used to stop other people starting a charge.
- **IP and IK ratings:** IP rates protection against dust and water (IP65 is dust tight and protected against water jets); IK rates impact resistance, from IK00 to IK10.
- **Vehicle-to-grid (V2G) and vehicle-to-home (V2H):** Sending power from the car's battery back to the grid or the home. It needs a bidirectional charger, a compatible car and approval from your network operator, and V2G also needs a supplier offer.
- **Smart tariff charger list:** The chargers an energy supplier says it can control for its smart EV tariff, such as Octopus's list for Intelligent Octopus Go. Suppliers add and remove chargers, so we show the date we checked.
- **EV chargepoint grant:** A GOV.UK grant for people who rent, or own a flat, with private off-street parking. It can cover 75% of the cost of buying and installing a chargepoint, up to £500 (checked 4 October 2026).
