What We Like About The Fronius Wattpilot Chargers

The Fronius Wattpilot series is designed for flexibility, allowing for both home and portable charging. They are one of the few chargers we’ve seen that you can take with you, which could be handy on a road-trip and is able to plug into a 3-phase socket at a caravan park or industrial area.

They offer flexibility and programming to ensure that owners minimise the charging costs using solar power and off-peak rates. The chargers can switch between 1 and 3-phase automatically, optimizing the use of surplus PV energy.

Key Features

Safety & Control: The Fronius Wattpilot ensures secure access through an approved RFID chip or card, allowing you to create up to 10 user profiles. Additionally, the charger comes with anti-theft protection, including a shackle for the Wattpilot unit and a locking option for the Type 2 charging cable.

Flexibility: One of the standout features of the Wattpilot is its universal compatibility with any electric car. This means if you decide to switch your EV down the line, there’s no need to change your charger.

Intelligent Charging: The Wattpilot is not just a charger; it’s a smart device. It can automatically toggle between 1 and 3-phase charging and fine-tune its output in small increments. This ensures you make the most out of any surplus solar energy, while also avoiding any load peaks, ensuring a stable power supply to your home.

Dynamic Load Balancing: If you’re a multi-EV household, the Wattpilot has you covered. It can dynamically distribute the available current and charge up to three electric cars simultaneously in an energy-optimized manner.

Full Integration: For those who like to keep tabs on their energy usage, the Wattpilot seamlessly integrates with the Fronius Solar.web app. This provides a comprehensive overview of your PV system and allows for real-time monitoring of your self-generated solar energy.

How Much Does the Fronius Wattpilot Charger Cost?

Pricing varies depending on the model but the 22kW Go model with a 5m Type 2 cable will set you back around $2,200 plus installation.

Pros and Cons

Seamless connection with Fronius solar system and monitoring portal

Excellent app and flexibility in programming

Reputable company with well-established support in Australia
More expensive than most residential charging options on the market

Less benefits for users who don’t have a Fronius solar system installed

The charger does not have an LED display meaning the user cannot configure charge or settings without the app


  • Clearly displays all charging data
  • Change charging modes remotely
  • Apple users 2.3 / 5 for 5 reviews


Installation should be performed by a qualified electrician and typically takes a few hours. If you opt for the portable “GO” model, you will get a 3-phase plug wired into the charger. You will need to ensure you have a suitable wall socket in your premises to plug this into. 

If you opt for the home option, the charger will be mounted and hardwired to the wall.

Should I Buy a Fronius Wattpilot Charger?

If you’re looking for a portable, versatile and intelligent EV charger, the Fronius Wattpilot series is worth considering. Should you already have a solar system with a Fronius smart meter installed, then this will link in nicely to your system and monitoring portal.

If you have another solar inverter brand installed there may be extra costs involved with connecting your solar system to the charger.
