The Fronius Ohmpilot is a power controller that uses excess solar energy to heat water.
It can adjust output from 0 to 9 kW, allowing surplus solar power to be used efficiently within the home instead of being exported to the grid.
The Ohmpilot is mainly used to control heating elements in hot water systems, such as boilers and buffer tanks. It can also be used with infrared heaters or towel rails.
With this setup, a typical household can cover most of its hot water needs using solar energy, especially between September and March. This helps increase self-consumption, lower CO₂ emissions, and reduce load on the main heating system during warmer months.

The Fronius Ohmpilot uses excess solar power from your PV system to heat water in your hot water system. This means you can use solar energy instead of other heating sources like gas, oil or pellets.
It can adjust power output from 0 to 9 kW, helping you use your solar energy more efficiently. The Ohmpilot can also control other loads such as towel rails and infrared heaters.
Intelligent Heating
The Ohmpilot helps reduce the load on your main heating system by using surplus solar energy for hot water or heating. In some cases, you may not need to use your main heating system at all during the warmer months. This can help save money and reduce wear on your system over time.
More Self-Consumption
Using more of your own solar power makes sense, especially if there are limits on how much energy you can export to the grid. The Ohmpilot helps you use excess solar energy for heating water or your home, reducing energy costs and reliance on electricity providers. Even small amounts of extra solar power can be used.
Clear Monitoring
The Ohmpilot can be monitored through Fronius Solar.web, along with other Fronius components. This gives you a clear and simple view of system performance
