Fronius Tauro ECO 50-3-D

Fronius Tauro ECO 50-3-D with 50 kW – the new commercial inverter

As of January 1, 2023, purchasing warranty extensions can only be done via the Fronius SolarWeb web shop.

Fronius is launching the Tauro three-phase commercial inverter. The inverter is available in two system designs. On the one hand, there is the Direct variant, in which the Tauro can be placed decentrally directly at the respective module field. The system design is characterized by short DC cable lengths and longer AC cables. If the Tauro is installed centrally with a short distance to the main AC distribution board, the Precombined variant is to be used. The central plant system is characterized by a longer DC bus line. Both variations are ideally suited for rooftop and ground-mounted systems. They are available with 50 or 100 kW. The Tauro can be mounted both horizontally and vertically. In addition, with the help of the cooling technology and double-walled front cover, maximum output can be achieved even in full sunlight.
