The Hypervolt Home 3 Pro HV3PROAASG075T2 is a 7.4kW single-phase tethered EV charger with a 7.5m Type 2 cable in Space Grey. It is the middle cable-length option in the Space Grey Home 3 Pro family, sitting between the compact 5m model and the longest 10m version. The 7.5m lead suits driveways where the charge point cannot be mounted directly next to the vehicle inlet, while still keeping cable handling more manageable than a 10m lead. The charger supports app control, scheduled charging, solar modes, lock function and automatic load management. Its IP66 and IK10 enclosure ratings support exposed home installations when the unit is installed correctly. For buyers comparing variants, this model belongs in the approved Hypervolt collection and the wider home EV chargers category.

Why choose the 7.5m Space Grey cable?

The 7.5m cable is often the practical middle ground for domestic driveways. It gives extra reach where the charger is mounted by the consumer unit route, meter position or garage wall, rather than exactly beside the vehicle inlet. That helps customers whose car may be parked nose-in one day and reversed in the next.

This cable length also gives more tolerance for future vehicle changes. A new EV may have its AC inlet on the opposite side or at the rear quarter, and a 5m lead can become restrictive when the parking habit changes. The 7.5m variant keeps the Home 3 Pro tethered convenience while reducing the likelihood that the customer needs to replace the charger later for cable reach alone.

Charging modes for solar and schedules

The Home 3 Pro gives the user Boost, Eco and Super Eco modes. Boost is for direct full-output charging, Eco uses solar and grid input, and Super Eco is the solar-only mode within the charger’s mode list. That makes the charger useful for homes with existing PV generation and for customers who want a charger that can sit alongside a future solar installation.

Scheduled charging and the lock function are available through the Hypervolt app. Scheduling lets the user align charging sessions with planned departure times or off-peak windows. The charger can also be controlled through app settings for maximum charge rate and LED brightness, giving the household some control over how the unit behaves day to day.

Official tariff support is important for customers specifying a charger around running costs. Octopus provides Hypervolt connection steps for Intelligent Octopus Go, while OVO lists the Hypervolt Home 3 Pro as compatible with Charge Anytime. Link customers comparing tariff support to EV tariff guidance or the LAMPS page on Intelligent Octopus Go compatible chargers.

Protection and load management detail

For HV3PROAASG075T2, Hypervolt lists internal 6mA DC RCD-DD and integrated PEN fault protection. The charger still requires external AC protection, and the manufacturer recommends Type A double-pole overcurrent protection using a B or C curve 40A device. This should be selected by the installer after assessing the supply, cable route and site conditions.

The integrated PEN fault protection removes the need for an additional earth rod on PME supplies when installed in line with the manufacturer guidance. The system is designed to isolate all conductors if the protective earth and neutral conductor is damaged or disconnected. Compatible earthing systems listed for the Home 3 Pro include TN-C-S, TN-S and TT.

Automatic Load Management uses a CT clamp at the service origin to measure the property load and solar export. When activated, the charger can reduce charging current to as low as 6A to avoid the charging load overloading the electrical service to the property. Installers working on constrained supplies should review the ALM setting as part of commissioning rather than leaving it as an afterthought.

Wi-Fi, Ethernet and commissioning

The charger supports Wi-Fi at 2.4GHz and Bluetooth LE 4.2, with an internal RJ45 connection for optional hardwired Ethernet. Hypervolt recommends hardwired Ethernet as an option because it is less affected by atmospheric changes and Wi-Fi stability issues. This matters where the charger is fitted to an outside wall, detached garage or meter cupboard area with weak signal.

Cable planning involves both the electrical supply and CT data. The installation guide states that the Hypervolt requires one connection for supplying electricity and one for sending CT information. CT wiring can be extended up to 50m using Cat5e cable or 100m using HyperConnect or EV-Ultra cable, which gives practical options for longer meter-to-driveway layouts. Approved EV cabling can be reviewed alongside the charger before the install is booked.

The installer app supports adoption, network configuration, customer handover and automated tests. After installation, the unit must be registered as installed within 48 hours to validate the warranty. That point should be included in the handover process because the installation guide states that failure to register within that period will void the warranty.

Space Grey variants compared by reach

The Space Grey siblings differ by cable length only. Choose the 5m Space Grey Home 3 Pro when the vehicle inlet sits close to the wall and the customer wants the tidiest cable coil. Choose this 7.5m model when the mounting position, parking direction or vehicle inlet position needs more reach. Choose the 10m Space Grey Home 3 Pro where the charger must serve a longer bay, a second parking position or a more awkward route.

Colour choice is separate from cable choice. The 7.5m Ultra Black Home 3 Pro suits darker finishes, while the 7.5m Ultra White Home 3 Pro suits pale render and white exterior details. The Home 3 Pro technical platform remains the same across the colour variants.
