Three-phase string inverter Fronius Tauro 50-3-D | 50 kW

No rating yet

Product description

The Fronius Tauro 50-3-D is a three-phase string inverter with an output power of 50 kW, it is designed for maximum flexibility with minimal operating costs. Featuring active cooling and an IP65 chassis, this inverter performs reliably and consistently in all weather conditions - both in the rain and in direct sunlight. Thanks to its transformerless topology, it can reach up to 98.5% efficiency. The Tauro 50-3-D has a clever double walled design with replaceable power stages and integrated electrical panel for DC fuses and surge protection devices, making installation and maintenance easier than ever. The inverter is equipped with a comprehensive set of interfaces, communication options, data logging, and web-based remote management features.

Additional specifications and description

The Fronius Tauro 50-3-D is suitable for industrial applications and large commercial PV systems without battery storage.
The inverter has a robust design and active cooling, allowing it to be mounted outside without risk of damage or degraded performance.
Unlike most other inverters, the Tauro 50-3-D doesn't need to be wall-mounted - by using the optional stand, the inverter can be placed horizontally on any suitable surface.
Integrated data communication
Fronius was the first inverter manufacturer to offer a comprehensive suite of communication features in its inverters as standard. The Tauro 50-3-D has data logging, WLAN, Ethernet, energy management, a web server and all the necessary interfaces to connect to third-party devices. The inverter can connect to the Internet via an Ethernet cable or a Wi-Fi network and is accessible via the Solar.web portal. Connection to third-party components is provided by means of interfaces such as Modbus TCP SunSpec, Modbus RTU SunSpec or the Fronius Solar API (JSON).
Dynamic Peak Manager
Fronius has developed its own advanced MPP tracking algorithm called Dynamic Peak Manager. The algorithm dynamically adapts its behaviour when searching for the optimal maximum power point.
By scanning the entire curve, Dynamic Peak Manager can reliably and quickly find the global maximum power point (GMPP), regardless of the constantly changing lighting conditions caused by clouds or partial shading.
Active Cooling
The Tauro 50-3-D utilises active cooling fans, which circulate the air inside the power stage compartment of the inverter.
Active cooling maintains the power electronics at optimal temperature and prevents heat spots and overheating.
The result is prolonged service life, optimised yields and reduced costs.
Double wall design
The Tauro 50-3-D is split into two compartments, separating the power stage and connection area/electrical panel. Not only that the power stage is modular and easily replaceable by one person in the unlikely event of a failure.
This design significantly simplifies maintenance and reduces downtime, which is especially desirable for large commercial PV systems.
Adjustable or zero feed-in
When a compatible energy meter is connected, the Tauro 50-3-D allows users to set a grid feed-in limit, including the option for zero feed-in. The inverter prioritises supplying power to the user and dynamically adjusts its output to the grid, staying within the defined feed-in parameters.
