MUNICH, Germany, June 7, 2011 (GLOBE NEWSWIRE) -- INTERSOLAR EUROPE 2011 -- 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 will present new products from its AURORA® range at Intersolar Europe.

The world's largest exhibition for the solar industry will take place in Munich, Germany, from June 8th to 10th. At the show, Power-One will launch four new PV inverters: the AURORA MICRO-0.3 micro-inverter, the redesigned AURORA UNO-2.0 and UNO-2.5 single phase inverters, the AURORA TRIO-27.6 and TRIO-20.0 three-phase string inverters and the AURORA ULTRA-1400, the largest inverter currently available with an output of up to 1.4MW.

In addition, Power-One will also present the new category AURORA Vision consisting of monitoring and control products, services and solutions.

"The new offerings expand our broad array of products and services for the solar market," said Dr. Alex Levran, President of Renewable Energy Solutions at Power-One. "We are excited to present not only several new inverters which combine high innovation content and key features, but also to introduce the AURORA Vision offering which provides greater system control and yield for our customers."

AURORA MICRO-0.3

The MICRO-0.3 is a real alternative to the traditional string inverters Power-One is well-known for and offers customers attractive benefits. The device minimizes efficiency losses in challenging conditions, because every module benefits from a separate MPPT creating the optimum power curve for individual panel conditions. Moreover, the micro-inverter allows for controlling every module individually, ease of plant expansion without the hassle of string re-sizing or panel matching and offers efficiency ratings of up to 95.5 percent.

AURORA UNO-2.0 and UNO-2.5

The redesigned UNO-2.0 and UNO-2.5 single phase inverter is Power-One's smallest residential inverter, having the right size for the average rooftop installation with 2kW output (also available with 2.5kW). Packed with Power-One's proven high performing technology, this HF-isolated inverter offers new features like a special built-in heat sink compartment and a front panel user interface. Moreover, this extremely robust outdoor inverter provides a high speed MPPT, offering real-time power tracking and improved energy harvesting, a wide input voltage range and an efficiency of 96.3 per cent.

AURORA TRIO-27.6 and TRIO-20.0

With its two new string inverter products for large roof top applications, Power-One fills the gap between its previous 10.0kW and 12.5kW three-phase products and its smallest 50kW and 55kW central inverters. The new AURORA TRIO-27.6 and TRIO-20.0 benefit from the technology perfected in the
PVI-10.0 and 12.5, probably the world's most commonly used three-phased inverter, which has led the way in best-in-class efficiency. The size, larger than its smaller predecessors, allows the new devices to offer more flexibility and lower wiring cost to installers who have large installations with varying aspects or orientations. Both inverters offer a number of differentiating features, including two independent MPPTs, a special built-in heat sink compartment and an efficiency rating of up to 98.3 percent. The unit is free of electrolytic capacitors to further increase the life expectancy and long term reliability.

AURORA ULTRA-1400

The new ULTRA-1400 is the largest solar power inverter currently in the Power-One AURORA product range. Designed for large utility-grade installations, this liquid-cooled, high-powered inverter offers maximum power for a minimum footprint. The new concept also features an IP65 enclosure, low maintenance and operational costs. Industry-leading power conversion efficiencies of up to 98.7 percent, combined with up to four high-speed MPPT channels, optimize energy harvesting across a wide array of operating conditions. This very large inverter system significantly reduces the wiring requirements and on-site testing thanks to separated and dedicated compartments for DC and AC.

AURORA Vision

With the new category AURORA Vision, Power-One helps its customers to maximize the return of investment of renewable energy projects through better understanding and communication between the user and the installation.

The new AURORA Vision has three key offerings: software, hardware and accessories. To maximize system energy output while minimizing costs, the software includes a full range of system fault management, diagnostics, asset tracking, performance index and alerting services as well as revenue information. The hardware section of AURORA Vision offers equipment designed to capture data and environmental information to allow the transfer between inverter, installation and owner. Accessories such as the desktop monitoring system and the EVO Easy control, which help to monitor the performance of connected inverters over the internet, complete the AURORA Vision portfolio.
