Fronius Tauro & Tauro ECO Designed to perform.

The robust inverter for large-scale PV systems

Powerful in any situation: the robust Fronius Tauro inverter impresses not only by offering maximum flexibility in terms of system design, but also by its minimal overall system operating costs. The robust project inverter makes commercial large-scale photovoltaic systems even more cost-effective.

Quick installation and efficient maintenance
Power electronics protected by active cooling
Double-walled housing ensures optimum temperature compensation
Stable high performance even at ambient temperatures of up to 50 °C

Fronius Tauro: Designed to perform.

Fronius Tauro

Power category: 50 kW
Ideal for challenging PV configurations

Fronius Tauro ECO

Power categories: 50, 99,99 & 100 kW
Ideal for cost-optimised systems

Robustly designed for long service life

Direct sunlight and high temperatures are no problem for the robust Fronius Tauro. On the contrary: the robust project inverter was specially developed to deliver unrestricted full power even under the harshest environmental conditions.

Double-walled housing ensures optimum temperature compensation
Stable high performance even at ambient temperatures of up to 50 °C

Extremely cost-effective

Fast installation and fast service: Fronius Tauro is quick to install and efficient to maintain. If necessary, only the affected power stage set needs to be replaced on site rather than the entire project inverter, thereby saving time and conserving resources.

Quick installation and efficient maintenance
Power stage set replacement (27 kg) is easily accomplished by one person
Efficient handling of service cases and targeted online support with Fronius Solar.SOS

Everything at a glance

Pretty smart: Fronius Tauro – like all Fronius products – can be conveniently monitored, controlled and maintained from a smartphone or PC.

Additional elements and third-party components are easily integrated thanks to the open system architecture.

Maximum design flexibility

Fronius Tauro offers maximum flexibility in terms of both system design and installation. Whether centralised or decentralised, vertical or horizontal: the Fronius Tauro series can be easily adapted to customers’ individual needs and circumstances. To this end, the flexible Tauro and the cost-effective Tauro ECO can be combined with each other in any way you choose.

The 30 amperes version of the Fronius Tauro Direct is also designed for larger PV modules with high amperages.

Practical AC daisy chaining also makes it possible to link multiple inverters together. This saves on additional components and cabling, thus keeping the overall system operating costs low.

Fronius Tauro The product advantages of the robust inverter at a glance

Double-wall design With its double-walled housing, the Tauro ensures optimum temperature compensation and protects the sensitive power electronics from overheating.

Centralised and decentralised system Depending on the requirements, Fronius Tauro can be used in a centralised (precombined) or decentralised (direct) system design.

Connection options On the AC side, cable cross sections of up to 240 mm² can be implemented. This not only allows maximum planning flexibility, but also means huge cost savings in ongoing operation.

Flexible installation Practical brackets allow Fronius Tauro to be installed vertically or horizontally.

Sustainable throughout

From production to maintenance: sustainability is our promise.

For more than 75 years, Fronius has stood for intensive research, innovative technologies, high-quality products and cost-effective solutions over generations. Fronius Tauro shows that sustainability at every stage of the product cycle pays dividends. The commercial inverter is designed for durability and was developed and produced in Austria with the fewest possible replaceable components. This makes Fronius Tauro particularly robust and failure-resistant, and means that only individual parts need to be replaced during on-site servicing, thereby saving time and conserving resources.
