Wattpilot Flex: Maximum efficiency for charging with solar power
For those who like to be ahead of the game, Fronius offers the perfect combination of elegant design* and state-of-the-art technology with the Wattpilot Flex.
The Fronius EV charger uses every ray of sunshine from your PV system** to charge your car as efficiently as possible for the next day. Intelligent charging modes enable cost-effective and efficient use of the solar power generated by your own PV system. The ideal electric car charging station for your home—sustainable, flexible, and cost-efficient.
* The Wattpilot Flex is supplied in the limited edition with embossed logo and the standard version with classic red logo. The product delivered will be allocated based on availability at dispatch.
** Additional components are required for charging with surplus PV energy. All the details can be found in the operating instructions.
Charge and save with the power of the sun
Charging your EV at home can be significantly more affordable than filling up with petrol. With typical EV consumption of around 18–20 kWh per 100 km and an average Australian electricity price of around 30 cents per kWh, driving 100 km costs approximately $5–$6 when charging from the grid.
If you have solar, charging becomes even more cost‑effective. Using your own excess solar energy can reduce the cost to around $0–$3 per 100 km, depending on your solar generation and electricity tariff.
In comparison, a typical petrol car using 8 L/100 km at an average price of about $1.75 per litre costs roughly $14 per 100 km. Over an average annual driving distance of 15,000 km, this can mean hundreds of dollars in savings every year.
With the Fronius Wattpilot Flex, you can maximise your solar self‑consumption, reduce charging costs, and improve the return on your solar investment, all with smart, flexible EV charging.

Maximum sun
Your energy, your e-mobility. With the Fronius Wattpilot Flex, you can charge your electric car very economically with self-generated solar power. The PV-optimized wallbox automatically switches between 1 and 3 phases to make the best possible use of the sun's power. From 1.38 to 11 or 22 kW (depending on the version), PV surplus is optimally used. No ray of sunshine is wasted.
Thanks to intelligent charging modes, you always have the choice: Eco Mode gives priority to solar power, while Next Trip Mode ensures that exactly the right amount of energy is charged at the right time for your next trip.
If you have a PV system, Fronius Wattpilot Flex gives you a double benefit: you save on charging and also increase your own consumption - which speeds up the amortization of your PV system.
