Tauro / Tauro ECO — 50 kW grid-tied inverter for large PV plants
Country: Austria · Model: Tauro / Tauro ECO
Rated at 50 kW with up to 1,000 V DC input, the Tauro three-phase string inverter goes onto commercial rooftops and ground-mounted PV plants. The Tauro version has 3 MPP trackers with a 400–870 V range, while the simpler Tauro ECO uses one tracker in a 580–930 V window. It mounts indoors or outdoors, even in direct sun.

Description
Several inverters chain together on the AC side (daisy chain), and the terminals of the 50-3 models take aluminum or copper of 35–240 mm². The Direct (D) version takes strings straight onto MC4 connectors and comes with 20/30 A string fuses and optional AFCI. The Precombined (P) version suits centralized layouts fed by a combined 25–95 mm² cable. A DC disconnector, an RCMU and a type 1+2 SPD sit inside. After a fault, technicians swap a single power module on site rather than the whole unit. The double-walled IP65 enclosure is actively cooled and holds rated power up to 50 °C. Communication runs over Wi-Fi, Ethernet and 2 × RS485 with Modbus RTU SunSpec.
How to choose
Pick the version by array layout. Tauro, with three trackers and feed-in from 200 V, suits roofs with several orientations. Tauro ECO fits a uniform field with long strings and is lighter, 74 kg against 98 kg. If one unit must carry over 75 kWp of modules, look at the Tauro ECO 99-3 / 100-3 with up to 150 kWp. For 15–33.3 kW sites the Verto fits.
