Product Description

The Fronius Tauro 50-3-D Three-Phase Inverter is designed for commercial and industrial photovoltaic plants that require robustness, string flexibility, and continuous operation under demanding conditions. Its architecture with 3 independent MPPTs, double-layer enclosure with IP65 rating, and active ventilation ensures stable performance at high temperatures, while integrated protections reduce CAPEX in panels and increase installation safety.

Main Features

Nominal power: 50 kW three-phase AC (η max. ≈ 98.5%).
3 independent MPPTs with string input options of 20 A or 30 A.
Integrated protections: SPD type 1+2 on DC/AC, DC isolator, series fuses, and RCMU.
Double-layer IP65 chassis, active ventilation, and design suitable for direct solar radiation.
Open communications: Modbus TCP/RTU SunSpec, Ethernet/Wi-Fi, JSON API, and Solar.web portal.
AC Daisy Chaining function to reduce cabling and external protections.

Advantages or Benefits

Higher production on complex rooftops thanks to its 3 MPPTs with high current per channel.
Simplified safety and compliance by integrating 1+2 surge arresters and string fuses.
Lower total cost: modular maintenance, cloud monitoring, and remote diagnostics.
Multi-inverter scalability with centralized management and synchronization via Ethernet.
Reliable operation in hot and dusty environments due to its thermal design and IP65 rating.

Purpose or Applications

Ideal for industrial self-consumption, carport parks, and decentralized plants in logistics or retail warehouses. Allows AC hybridization with storage systems and zero feed-in control through bidirectional measurement.

Technical Specifications

Power	50 kW three-phase AC
Nominal voltage	PV input 200–1000 Vdc (typical Umpp 400–870 V); output 3~ 400/230 V 50/60 Hz
Format	Wall-mounted, IP65, double-layer enclosure with active ventilation

Compatibilities

Direct integration with Fronius Smart Meter (zero feed-in), Wattpilot (EV charging with surplus), Ohmpilot (DHW), and EMS/PLC via Modbus TCP/RTU. Advanced monitoring on Fronius Solar.web and external control via digital I/Os.

Fronius Tauro 50-3-D Three-Phase Inverter is a professional solution to maximize energy and reliability in C&I installations, reducing installation and operation costs without sacrificing safety or connectivity.
