TAURO Inverter
DESIGNED TO PERFORM
The three-phase Fronius Tauro in the 50 kW power class 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. The Fronius Tauro can be used to implement sophisticated roofs in both centralised (P variant) and decentralised system designs (D variant). Simplest installation and the fastest service on the market also guarantee maximum safety.
Fronius Tauro. Designed to perform.
NOTES FOR TECHNICAL DATA
