Fronius Tauro ECO 3-D - Robust inverter technology for large-scale projects


The Fronius Tauro ECO 3-D from the Tauro series is a powerful industrial inverter that has been specially developed for commercial solar systems and large-scale PV projects. Thanks to its robust design, active cooling and high IP65 protection class, it delivers maximum efficiency even under extreme conditions. Whether in solar parks or large rooftop systems - the Fronius Tauro ECO 3-D ensures reliable energy conversion and optimized operating costs.


Why the Fronius Tauro ECO 3-D?


  • Available with 50 to 100 kW output for maximum scalability.
  • Three MPP trackers (Tauro) or one MPP tracker (Tauro ECO 3-D) for flexible system design.
  • Maximum efficiency of up to 98.5 % for maximum efficiency.
  • Robust housing with active cooling - ideal for direct sunlight.
  • Easy maintenance thanks to modular system - only affected parts need to be replaced.
  • Smart control & open system architecture for easy integration into existing systems.

Comparison with other high-performance inverters

The Fronius Tauro ECO 3-D offers high performance, flexibility and easy maintenance - but how does it compare to other inverters?


The Huawei SUN2000-100KTL-M1 also relies on a modular architecture, but offers an integrated battery storage option, while Fronius scores with better repairability and open interfaces for third-party providers.

The Sungrow SG110CX has a higher maximum output of 110 kW, but lacks the robust design with double-walled housing that the Tauro ECO 3-D offers for extreme environmental conditions.

While Huawei relies on smart grid technology and Sungrow scores with a slightly higher output, the Fronius Tauro ECO 3-D impresses with maximum robustness, flexible system design and low operating costs - perfect for large-scale PV projects with high efficiency requirements.


Long-term investment security


  • 12-year product guarantee for maximum reliability.
  • Integrated overvoltage protection technology for maximum system safety.
  • Simple maintenance & modular design - reduces service costs and downtimes.

Conclusion - The robust inverter for large-scale projects


The Fronius Tauro ECO 3-D combines high performance, extreme durability and intelligent control. Whether in solar parks or commercial systems, this inverter offers maximum yields and an efficient, future-proof solution for demanding PV projects.
