Humax MX7 EV charger review

The Humax MX7 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 Humax MX7 right for you?

The questions most people start with, answered from Humax'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 Humax MX7 tethered or untethered?

Both

You can choose a fixed cable (5 m or 7.5 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
  • Fixed cable, 7.5 m
  • Socket for your own cable

Is the Humax MX7 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 Humax MX7 support V2H or V2G?

Not yet

Humax says its hardware is ready for vehicle-to-grid (V2G), but the feature is not active yet.

Can it stay connected without Wi-Fi?

No

It connects by Wi-Fi and has no mobile data, so check your Wi-Fi reaches the driveway.

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

Does the Humax MX7 need an earth rod?

Usually not

It has a built-in safety feature (Humax 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?

5 years

5 years, when registered online.

Humax MX7 features explained

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

What is the Humax MX7?

The MX7 is a single-phase home charger from Humax, sold through Humax Direct with or without installation. It comes as a socket version or a tethered version with a 5 m or 7.5 m cable, in black. Its distinguishing features are vehicle identification, which uses a PLC module to recognise approved cars, and V2G-ready hardware that is not yet active.

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

The MX7 charges at up to 7.4 kW on a 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

The socket version (SKU H95-0132) has a Type 2 socket. The tethered version (SKU H95-0131) has a Type 2 cable of 5 m or 7.5 m.

Solar charging with CT clamps

Humax calls its solar feature SolarSmart, or Auto Solar. It sends surplus solar power to the car once the home's own energy needs are met. A CT clamp and connector are supplied in the box.

Vehicle identification and bidirectional hardware

Humax says the built-in PLC module recognises your car when it is plugged in, so only approved vehicles can charge, and that charging is blocked and you are notified if an unrecognised car is plugged in. Humax says this can also separate personal and company-car charging for reimbursement.

The MX7 includes a PLC module and supports the ISO 15118 protocol, which Humax describes as V2G-hardware ready. Humax also states that V2G and V2H are "currently not commercially supported": AC-based V2G and V2H need the car and charger to be approved by the network operator, and the software and certification are still in progress. Humax says the MX7 cannot currently provide home backup power during an outage.

Smart charging with Octopus, E.ON Next and OVO

The Humax Charge app starts and stops charging remotely, shows charging history and energy use, manages schedules and handles multiple vehicles. Humax says tariff management prioritises off-peak electricity rates.

On the energy suppliers' own lists (checked 4 October 2026), Humax is not listed by Octopus for Intelligent Octopus Go, by OVO for Charge Anytime, or by E.ON Next for Next Drive Smart. Octopus and OVO can also connect through compatible cars rather than the charger.

Load balancing, earthing and installation

Humax lists built-in dynamic load balancing to keep charging within the home's available supply, and built-in PEN fault protection, stating that no earth rod is required. The charger has a tamper switch and a built-in temperature sensor. Humax Direct's standard installation includes up to 10 m of cabling, mounting on a suitable wall, protection equipment, testing, commissioning and notifications.

App, Wi-Fi and connectivity

The MX7 connects over Wi-Fi and Bluetooth. Humax recommends a stable Wi-Fi connection at the charger for app features, remote control and updates, and says basic charging works without an internet connection. Two RFID cards are supplied.

Build

Humax lists an IP65 rating and an ABS body, with adjustable LED brightness and a digital security lock. Humax does not publish dimensions, weight or an impact rating on the product pages we checked.

Warranty: 5 years

Humax Direct lists a 5-year warranty when the product is registered online.

Humax MX7 FAQs

How long does the Humax MX7 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.
Is there a grant for a home EV charger?
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.
Who can install the Humax MX7?
A qualified electrician who installs EV chargers. They check your fuse box and earthing, fit it on its own circuit, tell your local network operator, and set it up in the app. Our directory lists EV charger installers in 50 UK cities with their Google ratings.
Can the Humax MX7 do vehicle-to-grid?
Not yet. Humax says the MX7 has V2G-ready hardware (a PLC module and ISO 15118 support), but that V2G and V2H are currently not commercially supported, with the software and certification process still in progress. It also says the MX7 cannot provide home backup power during outages at present.
What is Humax vehicle identification?
Humax says the MX7's PLC module recognises your car when it is plugged in, so only vehicles you have approved can charge, and it notifies you if an unrecognised car is plugged in.
Does the Humax MX7 work with Intelligent Octopus Go?
Humax is not on Octopus's list of supported chargers for Intelligent Octopus Go, or OVO's or E.ON Next's lists for their smart tariffs (checked 4 October 2026). Humax says the MX7 can schedule charging into off-peak windows, and Octopus can also connect through some cars instead of the charger.
How much does the Humax MX7 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 Humax MX7 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.
