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.
- 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

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.
- Convenient monitoring, control and maintenance
- Open system architecture
- Easy integration of additional elements and third-party components

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.
- Flexible system design
- Tauro & Tauro ECO can be combined
- AC daisy chaining
- Integrated surge protection device
- Fewer components and cables required

The product advantages of the robust inverter at a glance
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.
- Sustainable development and production from Austria
- Innovative double-walled design
- Active cooling
- Simple component replacement
