Power-One, Inc. (Nasdaq:PWER), a leading provider of renewable energy and energy-efficient power conversion and power management solutions, today announced that the company’s innovative AURORA ULTRA central inverter system has been awarded second place at the “OTTI Innovationspreis” (OTTI Award for Innovation) by Ostbayrisches Technologie-Transfer-Institut (OTTI).
This award, presented every year at the Symposium Photovoltaische Solarenergie, honours outstanding new PV developments and products, which combine a high degree of innovation with benefits for the PV industry. This year, Power-One is the only inverter manufacturer which received an award at the 27. Symposium Photovoltaische Solarenergie, which took place in Bad Staffelstein, Germany, from February 29 to March 2.
“This is truly a great achievement for Power-One and an excellent recognition for one of our most innovative products,” said Dr. Alex Levran, President of Renewable Energy Solutions at Power-One. “There is no doubt that the AURORA ULTRA central inverter will continue to be an award-winning, show-stopping product for us for many years to come.”
With an output of up to 1.5MVA, the world’s largest central inverter system AURORA ULTRA has been designed with the specific needs of large und utility-scale installations in mind. The device convinced the jury with its modular design approach and innovative circuit topology. Since the modular structure is made of front accessible and extractible subassemblies, installation and maintenance procedures are very simple. Thanks to the innovative circuit topology the output voltage is 690Vac which allows a significant reduction of AC losses and the possibility of direct coupling with LV/MV standard transformers used in the large wind industry.
Furthermore, the award jury highlighted the fact, that Power-One’s central inverter system does not need an additional cabin, as its IP65 enclosure withstands even the harshest environmental conditions. A passive liquid cooling system allows segregating the active parts of the unit in a watertight and pollution-free chamber, further improving the system long-term immunity against aggressive environmental agents. This also extends the maintenance cycle and reduces the cost of maintenance.
The low cost and the high power conversion efficiencies were additional highlights the jury based its decision on. The new AURORA ULTRA offers industry-leading power conversion efficiencies of up to 98.7 percent over a wide input voltage range. Four high-speed MPPT channels optimize energy harvesting across a wide array of operating conditions. This large inverter system is compliant with the BDEW regulations (German Federal Association for Energy and Water).
