"These next generation, 75 to 135kW PowerGate Plus inverters began shipment to customers in April, and is the second launch of a new series of inverters that have been designed for high-efficiency, improved energy harvesting, and long-life," stated Clemens van Zeyl, President of SatCon's Power System Division. "These inverters have also been designed for ease of manufacture and maintenance, which will significantly increase our manufacturing capacity, reduce our lead-times, and reduce operating costs for our customers." "We are pleased to have these inverters available in the marketplace prior to the busy season in the USA, thereby adding additional value to our customers at a critical time of the year."

About PowerGate([R]) Plus Inverters

PowerGate inverters are designed for use with alternative and renewable energy power systems to generate distributed electrical power. Distributed, alternative and renewable energy power generation is a growing trend toward the production of clean, reliable power at the point of use.

SatCon's next generation of PowerGate([R]) Inverter, named PowerGate Plus, incorporates many of the features of the original inverter plus several improvements that add further value to photovoltaic power systems. The 30kW & 50kW series was launched in February of 2008, and the 75W, 100kW & 135kW series in April of 2008. These PowerGate Plus inverters utilize a proprietary enclosure constructed from long-life G90 galvanized steel, the latest advanced digital signal processing control, an advanced human machine interface (HMI) with display visible in sunlight and membrane keypad for easy identification of power system status and inverter setup, and many other features that add increased value to solar photovoltaic power systems.
