Complete Solution Provider to Preview New Inverters at Solar Power International 2011

Dallas, Texas—Solar Power International—October 18, 2011—Advanced Energy Industries, Inc. (Nasdaq: AEIS), booth #301 and #507-OD, today announced it will showcase its complete suite of energy management solutions at Solar Power International (SPI), in Dallas, Texas, October 17-20, 2011. This includes a new PV Powered HE String inverter line, the PV Powered 500 kilowatt (kW) inverter and the Advanced Energy (AE) Solar Plant Controller.

During SPI, AE will showcase the next generation of string inverters with the PV Powered (PVP) HE String line, an all-new line of high-performance string inverters ideally suited for North American residential and small-commercial rooftop installations. The new PVP HE String inverters are the first to offer high-efficiency and key ease-of-installation features from a company who has set the standard in inverter reliability. With a 97 percent California Energy Commission (CEC) efficiency the PVP HE String inverters produce more power throughout the day and have features that lower total installed cost. The PVP HE String line offers power ranges from 3.8 to 7 kW, is the industry's first inverter to offer standard ZigBee wireless monitoring and will be available in Q2 2012.

At the show, AE will also showcase the PV Powered 500 kW and Solaron 500 1kV inverters. The PVP 500 kW features the industry's first inverter integrated DC circuit breaker subcombiner, which enables low cost compliance with NEC2011 and improves serviceability. Designed for the needs of large commercial and utility-scale applications, the PVP 500 kW accelerates payback with an estimated 98.2 percent peak efficiency and 97.5 percent CEC efficiency. The highly configurable PVP 500 kW will begin shipping Q1 2012 and will also be available in a stainless steel enclosure. The Solaron 500 1kV Inverters provide durable, robust building blocks for utility-scale PV installations, featuring very high efficiency and new utility interactive controls, including fixed power factor to 0.90 leading or lagging, low and zero voltage ride-through (LVRT, ZVRT) and better over/under frequency response. Solaron 500 1kV models are outdoor ready for cost-effective installation.

Also new to the market, the AE Solar Plant Controller offers intelligent plant level control for enhanced grid integration of solar power. The AE Plant Controller provides customers with both the utility-scale power plant control they require as well as state-of-the-art actionable site performance metrology. Available in the North American market, the AE Plant Controller is a direct result of AE's work with the Solar Energy Grid Integration System (SEGIS) program, funded by the U.S. Department of Energy Solar Energy Technologies Program.

"All of AE's latest offerings continue to set the standard for both efficiency and reliability, enabling system owners and operators to achieve the highest levels of system-wide performance, intelligence and reliability," said Charles Loarridge, president of AE Solar Energy. "With 30 years of experience in power conversion, we understand project stakeholders' need for solar products that offer high performance and an outstanding long-term value, while at the same time offering flexible control, configuration and maintaining the lowest Levelized Cost of Energy."

Also on display at the AE booth will be the AE's new free web-based inverter direct monitoring service, as well as the company's innovative site monitoring and controls solutions. Additionally at the AE outdoor SPI exhibit, booth #507-OD, attendees can see the 2 MW PowerStation™. The pre-assembled, outdoor ready solution affords easy, fast and repeatable installations for utility-scale, multi-megawatt PV projects.
