Fronius Tauro Eco

THE POWERFUL INVERTER WITH A HARD SHELL AND A SMART CORE

The three-phase Fronius Tauro in the 50 to 100 kW power classes promises maximum performance, even under the harshest conditions. With its smart hardware design, it not only contributes to BOS cost optimization, but also offers unprecedented flexibility in system design. With the Fronius Tauro, both centralized (P variant) and decentralized system designs (D variant) can be implemented. Simplest installation and the fastest service on the market also guarantee maximum safety.
