Charging station for electric cars
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 in combination with a variable electricity tariff enable cost-effective and efficient use of the solar power generated by your own PV system. Where necessary, the Wattpilot Flex draws additional power from the grid when the price is lower for maximum range. The ideal electric car charging station for your home—sustainable, flexible, and cost-efficient.
*Additional components are required for charging with surplus PV energy. All the details can be found in the operating instructions.
Charging electric cars with cheap solar power
With the Fronius Wattpilot Flex, you can charge your vehicle cost-effectively using your own solar energy. The PV-optimized Fronius EV charger automatically switches between 1 and 3 phases to make the best possible use of the sun’s power. Depending on the version, surplus PV energy of 1.38 to 11 or 22 kW is used to optimal effect. Not a single ray of sunshine is wasted.
The Fronius charging station impresses with its modern design and outstanding functionality. The Fronius Wattpilot Flex even received the prestigious German Design Award 2025 for its excellent product design.
