Sungrow + Tado

Solar Heating with Sungrow and Tado

Combine the power of your Sungrow PV system with your Tado heat pump for intelligent solar heating. Zerofy monitors your real-time solar production and automatically adjusts control to match your available surplus.

What is Solar surplus heating?

Solar surplus heating means your heat pump 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 Sungrow + Tado 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

Dynamic Tariff Integration

Beyond solar surplus heating, Zerofy can optimize your Tado 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 Sungrow and Tado 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
