American Electric Technologies, Inc. (Nasdaq:AETI), a premium provider of power delivery solutions for the traditional and renewable energy industries, introduced its Integrated Solar Inversion Station™ (ISIS) at Intersolar North America 2010. ISIS is the industry's first completely pre-commissioned, utility-grade, 1MW, direct-to-medium voltage solar inverter system designed to provide greater, more reliable operating power for solar farms in the harshest environments. 

AETI's Integrated Solar Inversion Station is delivered to the farm as one integrated solution designed for IEEE 1547 and UL 1741 specifications. The 1MW system incorporates a photovoltaic (PV) master combiner and disconnect, dual 500 kW grid tie inverters, medium voltage switchgear and transformer, and integrated cooling system for quick deployment of solar power conversion, control and distribution. After being lifted from the truck to the pad and wiring it for operation, the station can immediately begin PV solar generation. 

The Integrated Solar Inversion Station inverts up to 1200 volts of PV power and outputs directly to 15-kilovolt (kV) medium voltage (MV) alternating current (AC) power collection systems - providing the highest output solar inversion solution on the market. This is facilitated by the station's PV interconnection system, dual redundant grid tie inversion system and MV interconnection system. The interconnection system includes a 12-circuit, 1600 amp direct current (DC) master combiner and disconnect switch. When the disconnect switch is opened, the system isolates itself from the grid with no arc flash, providing safer and higher performing solar power substation operations. 

"As a leading supplier of power conversion and distribution equipment for some of the world's most severe climates for more than 60 years, AETI is very much attuned to the industry's need for the highest level of solar farm operating efficiency and reliability available," said John Skibinski, vice president, renewable energies market development, AETI. "Our commitment to meet this need is a key driver behind an innovative approach that includes using utility-grade electrical and cooling systems components and additional PV panels per string to increase PV input and operating efficiencies beyond 97 percent. 

"Most important, AETI's Integrated Solar Inversion Station is completely pre-configured with all fuses, surge suppressors and lightning arrestors pre-tested - a critical feature that further promotes its reliability both short- and long-term and benefits construction crews by saving them time in the field," said Skibinski. 

The Integrated Solar Inversion Station is designed and manufactured for a 20-year life and climates that range from -40°C to 52°C without de-powering. It uses liquid-cooled UL listed power modules, redundant cooling fans, and dual grid tie inversion redundancy for continued operation. In addition, the station's integration bay allows factory installation of customer-specified PV string monitoring and tracking control systems. By integrating these features into the station's design, solar farm operators also benefit from reduced installation and commissioning costs.

"With the industry's reliability and cost efficiency needs addressed, AETI's Integrated Solar Inversion Station provides complete balance of equipment for PV power generation across solar farms today and in the future," said Skibinski. "And as solar farm demands continue to grow, operators now have a comprehensive power inversion solution they can rely on."
