Power-One will unveil new patent-pending inverter technology that promises to address the demands of the next generation of utility-scale commercial applications and solar parks at this year’s EU PVSEC in Hamburg. The company will also showcase the latest products from its Aurora family of inverters, designed for rooftop installations.
The 1.4 MW ULTRA central inverters are the first commercially available products using the company’s proprietary inverter concept. The California-based company says the units allow voltage conversion at the industrial standard 690Vac while significantly reducing AC losses. The company claims the inverter system offers power conversion efficiencies of up to 98.7% over a wide input voltage range.
“In achieving the maximum energy harvest for large commercial and utility-scale solar parks, the inverter system plays a critical role”, said Paolo Casini, vice president of product marketing. “Our new ULTRA central inverters increase the system uptime significantly, thus eliminating plant shutdown and reducing repair time. At the same time, the BOS costs are minimized, offering greater financial benefits to plant operators.”
Other core features include multiple MPPT channels for optimized energy harvesting, a modular construction for all main building parts as well as an IP65 enclosure with passive liquid cooling, which enables a total segregation of the active parts of the unit in a watertight and pollution-free chamber.
The Aurora TRIO-27.6-TL and the Aurora TRIO-20.0-TL three-phase string inverters for large roof top installations have an output of 27.6kW and 20.0kW, respectively, and are based on the Aurora PVI-10.0 and 12.5.
The devices feature two independent MPPTs, efficiency ratings of up to 98.3%, a wide input range and a built-in heat sink compartment, negating the need for fans.
All Aurora inverters comply with the grid requirements of the BDEW standard.
Dr. Marco Trova, Director of Technical Sales at Power-One, will present a lecture on the technology on Thursday, September 8, 2011 at 3:15 P.M, in Hall B7/ Booth B18.
