What the Wattpilot Flex does
Purpose-built to turn surplus solar into kilometres
Most EV chargers charge your car from whatever power is available. The Fronius Wattpilot Flex is designed around a different idea: charge from solar first, adapt to what is available, and never waste a ray of sunlight. It adjusts its charging rate dynamically based on your live solar generation, scaling from as low as 1.38kW right up to 11kW or 22kW depending on the model. When solar generation drops, it steps down rather than stopping. When surplus increases, it steps up. The result is more of your own solar ending up in your car and less being exported to the grid at the feed-in tariff rate.

Who the Wattpilot Flex suits
The natural EV charger for Fronius Gen24 owners
The Wattpilot Flex works with any electric vehicle and any home electrical supply. It delivers its best performance when paired with a Fronius Gen24 inverter and Fronius Smart Meter, where the solar surplus integration is fully automatic. For Fronius system owners, it is the most seamless EV charging option available.



Townsville and EV charging
Why solar EV charging makes particular sense in Townsville
Townsville’s 320 sunny days a year mean most solar systems generate a surplus during the middle of the day that currently gets exported to the grid. The Wattpilot Flex is designed to capture that surplus and put it into your car instead. Given Townsville’s high solar resource, the gap between what you pay to charge from the grid versus what it costs to charge from your own generation is larger here than in most Australian cities.
Important to know
A note on solar integration requirements
The Fronius Wattpilot Flex works with any home as a smart scheduled EV charger. However, the automatic solar surplus charging feature that makes it stand out requires a compatible Fronius inverter and a Fronius Smart Meter. Without these, you can still use the charger with grid power and schedule charging through the app, but the charger will not automatically detect and use solar surplus.
If you have a non-Fronius inverter and want automatic solar surplus charging, the GoodWe HCA G2 or Sigenergy AC wallbox may be more appropriate depending on your existing equipment.
If you have or are planning to install a Fronius Gen24, the Wattpilot Flex is the most seamlessly integrated option and the one we recommend for Fronius system owners.
