TAURO Inverter 

DESIGNED TO PERFORM

The three-phase Fronius Tauro in the 50 kW 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.

NOTES FOR TECHNICAL DATA

1) According to IEC 62109-1  

2) Unrestricted voltage range

3) At 580Vdc / 800Vdc / 930Vdc

4) Direct in the sun is possible

5) At an ambient temperature of 50°C

6) AC-, DC -Overvaltage protection; Typ 1+2: Iimp 5kA

7) An Ethernet star-configuration is used for communication with multiple inverters. Each individual inverter communicates independently with the network/Internet via its integrated data logger

8) Find more certifications at www.fronius.com/tauro-cert 

9) At 230 V actual mains voltage; design recommendation (Umpp min): 600V

 

* Isc pv = Isc max ≥ Isc (STC) x 1,25 according to e.g..: IEC 60364-7-712, NEC 2020, AS/NZS 5033:2021.
