TSUN + Fronius: TL;DR
Connect your TSUN solar system with your Fronius EV charger using Zerofy. Automatically charge your EV with solar surplus or optimize for dynamic electricity tariffs. No additional hardware required – setup in minutes via cloud.
Solar Charging with TSUN and Fronius
Combine the power of your TSUN PV system with your Fronius EV charger for intelligent solar charging. Zerofy monitors your real-time solar production and automatically adjusts control to match your available surplus.
What is Solar surplus charging?
Solar surplus charging means your EV charger operates primarily with the electricity your solar panels produce. Instead of feeding excess power to the grid at low rates, you use it yourself – saving money and maximizing self-consumption.
With TSUN + Fronius via Zerofy:
- Automatic adjustment – Control follows solar production in real-time
- Smart scheduling – Combine solar usage with time-based rules
- Smart Mode – Uses forecasts of household consumption and solar production
How It Works

Connect Fronius
Add your Fronius EV charger via cloud login
Enable Autopilot
Turn on solar surplus charging mode
Use Smart
Your EV charger operates automatically with solar power
Dynamic Tariff Integration
Beyond solar surplus charging, Zerofy can optimize your Fronius for dynamic electricity tariffs based on EPEX Spot or Nordpool prices (e.g., Tibber, aWATTar, Energinet) or any manually defined tariff schedule.
Unlike simple “cheapest hours” approaches, Zerofy’s Smart Mode goes further: it uses forecasts of your household consumption and solar production to find the overall optimum.
Why No Hardware Required?
Traditional solar controllers require a dedicated hardware box. Zerofy takes a different approach:
- Cloud-to-cloud integration – Connects directly to TSUN and Fronius cloud APIs
- No electrician needed – Setup takes minutes, not hours
- No upfront cost – Just download the app and connect
- Always up-to-date – New features added automatically
