Austrian inverter manufacturer Fronius has unveiled Fronius Tauro, a new inverter solution for large-scale solar power plants that can be deployed with a decentralized approach next to the PV modules or centralized at the grid connection point.
The three-phase device is available as a Tauro and Tauro ECO and has a power output ranging from 50 to 100 kW. It measures 755 x 1,109 x 346 mm for all four variants of the new product. The 50 kW product weighs 92 kg while the 99 kW and 100 kW versions weigh 103 kg.
The efficiency of the 50 kW device is 98.6% and that of the 100 kW product is 98.5%. The European efficiency for the two inverters is 98.1% and 98.2%, respectively.
The 50 kW Tauro device comes with three maximum power point tracking (MPPT) inputs while its DC input voltage range is 200-1000 V. Its maximum input current (DC) spans from 134 A to 175 A and the maximum short circuit current from 72A to 125 A. “The Tauro ECO has one MPP tracker, is optimized for cost and efficiency and is available in the 50, 99 and 100 kW power categories,” the manufacturer specified.
The new product is equipped with IP65 protection, active cooling technology, a double wall system and can be used with temperatures ranging from -40 degrees Celsius to 65 degrees Celsius.
“A reduction in the BOS costs, which can account for roughly a third of the investment costs (CAPEX), make the Tauro unbeatable,” Fronius explained. “The innovative AC Daisy Chaining option allows the installer to link the AC cables of a number of Tauro inverters together directly in the device.”
The inverter's housing offers enough room in the AC connection area for third-party components, according to the company. “No external box or similar is required, thus saving on costs. V-type terminals and a mounting bracket ensure extremely easy handling, saving more money as fewer additional components such as cable lugs are required.”
The Fronius Tauro Eco inverter will be available starting from June and the Tauro device from September.
