Wallbox 7 kW Solax X1-HAC-7S Home Car Charging
The Solax X1-HAC-7S is a 7.2 kW single-phase wallbox for home charging of electric and plug-in hybrid vehicles, with a Type 2 socket, IP65/IK10 protection rating, and management via the SolaX app.
Can be integrated with your photovoltaic system to charge your car using surplus solar energy (zero-export), it supports RFID, Wi-Fi/LAN, and the OCPP protocol. Wall-mounted installation by a qualified electrician.
The Solax X1-HAC-7S is a 7.2 kW single-phase wallbox designed for home charging of electric and plug-in hybrid cars. It is wall-mounted and connects to the standard single-phase home line, without redesigning the electrical system. Thanks to integration with the SolaX photovoltaic inverter (or with OCPP-compatible systems), it allows you to charge your car using surplus solar energy, maximizing self-consumption and reducing grid draw.
What is the Solax X1-HAC-7S wallbox for?
A wallbox is a fixed charging station, much safer and faster than a traditional household socket. With its 7.2 kW single-phase power, the X1-HAC-7S drastically reduces charging times compared to the “Schuko” cable supplied with the car (limited to 2–3 kW) and protects the system thanks to integrated protections, including 6 mA DC fault detection (DC 6 mA), which avoids having to install an expensive upstream Type B RCD.
It is the ideal solution for those who have a photovoltaic system: the dynamic load balancing system, combined with the included current sensor (CT), prevents exceeding the contracted power and directs to the car the solar energy that would otherwise be fed into the grid at a low price.

How long does it take to charge my car?
With a 7.2 kW single-phase wallbox, charging times depend on two factors: the car’s battery capacity and the maximum AC power the car’s onboard charger can accept. On a single-phase line, most cars charge at around 7 kW; some budget city cars stop at 6.6 kW. Here is a realistic estimate for the most common and best-selling models in Italy in 2025:
| Electric car | Battery (kWh) | Power with this wallbox | Charge 0→100% | Charge 20→80% |
| Tesla Model 3 (RWD) | ~57 kWh | 7.2 kW | ~8 hours | ~4h 45min |
| Tesla Model Y (RWD) | ~60 kWh | 7.2 kW | ~8h 20min | ~5 hours |
| Leapmotor T03 | ~37.7 kWh | 6.6 kW | ~5h 45min | ~3h 25min |
| Dacia Spring | ~27 kWh | ~6.6 kW | ~4 hours | ~2h 25min |
| Fiat 500e (42 kWh) | ~37 kWh usable | 7.2 kW | ~5h 15min | ~3h 10min |
| Renault 5 E-Tech (52 kWh) | ~52 kWh | 7.2 kW | ~7h 15min | ~4h 20min |
| Jeep Avenger Electric | ~51 kWh | 7.2 kW | ~7 hours | ~4h 15min |
| Volkswagen ID.3 Pro | ~58 kWh | 7.2 kW | ~8 hours | ~4h 50min |
| Peugeot e-208 (50 kWh) | ~46 kWh usable | 7.2 kW | ~6h 30min | ~3h 50min |
| BYD Atto 3 | ~60 kWh | ~7 kW | ~8h 40min | ~5h 10min |
Times are indicative estimates calculated based on battery capacity and actual AC power drawn; they may vary depending on temperature, battery condition, and the car’s onboard charger. In practice, for almost all of these cars overnight charging is more than enough to set off every morning with a full battery: plug in the car in the evening and when you wake up it’s ready, just like you do with your smartphone.
Charging with solar: Green, Eco and Fast modes
The real strength of the X1-HAC-7S is its communication with the solar system. You can choose three modes from the SolaX app:
- Green: the car charges only with surplus solar energy, at zero cost. Power automatically adapts to current production.
- Eco: mainly uses solar and supplements from the grid only as needed to keep charging stable.
- Fast: maximum power from the grid (7.2 kW), useful when you’re in a hurry or charging at night with a convenient time-of-use tariff.
A concrete example: a 4 kWp photovoltaic system on a sunny day in Rome can supply the wallbox with several hours of free energy, enough to recover 100–150 km of range per day at no cost.
What’s included and how it’s installed

Frequently asked questions
How long does it take to charge a Fiat 500e with this wallbox?
With the 7.2 kW Solax X1-HAC-7S, a Fiat 500e (42 kWh version, about 37 kWh usable) charges fully in about 5 hours and a quarter, and from 20% to 80% in just over 3 hours. Overnight charging is therefore more than enough to cover daily use.
Is the X1-HAC-7S compatible with my electric car?
Yes. The wallbox has a Type 2 socket (European standard IEC 62196) compatible with all 100% electric and plug-in hybrid cars sold in Europe: Tesla, Fiat, Renault, Volkswagen, BYD, Jeep, Dacia, and so on. As it is the “S” socket version, you will use the Type 2 cable supplied with your car.
Can I charge the car only with the energy from my photovoltaic system?
Yes, it’s one of the main functions. In “Green” mode, the X1-HAC-7S charges the car exclusively with surplus solar energy that you would otherwise feed into the grid, automatically modulating power based on production. This way you charge at zero cost and increase your system’s self-consumption.
Do I need a special RCD to install it?
No. The wallbox integrates 6 mA DC fault detection (DC 6 mA), so upstream a standard Type A RCD is sufficient, without having to install the more expensive Type B breaker. Installation must still be carried out by a qualified electrician in accordance with DM 37/2008.
Does it work with a normal single-phase home line?
Yes, it is designed specifically for the 230 V single-phase domestic line. Thanks to the included current sensor and dynamic load balancing, charging power is automatically reduced when other household appliances are running, preventing the meter from tripping.
Can I manage who charges and schedule times?
Yes. Authentication via RFID, NFC or the SolaX app allows only authorized users to charge, which is useful in shared settings. From the app you can also schedule charging during the cheapest time slots (for example at night) and monitor consumption and history in real time.
Is it suitable for outdoor installation?
Yes. The IP65 protection rating makes it resistant to rain and dust, while the IK10 class ensures impact resistance. It can therefore be installed both in a carport and garage and on an external wall, in a courtyard or under a canopy.
