GE Power Conversion ProSolar Central Solar Inverter ProSolar Central Solar Inverter The ProSolar central solar inverter is the latest development in inverters specifically designed for the solar industry. Part of GE’s ongoing developments in power electronics technology, the ProSolar inverter builds on extensive experience of designing and installing over 26 GW of converters for the renewable energy industry. The installed base covers the full range of utility scale requirements, including converters to meet even very stringent grid code requirements in extreme environmental conditions. 1,500 VDC capability Solar panel technology is continually evolving to help lower the cost of energy production. The next step in this trend is the 1,500 VDC panel which, by increasing the voltage level, enables higher output power capability by up to 50 % - thus decreasing system losses and balance of plant costs. Features • 1,000/1,500 VDC voltage level • Three-level inverter for higher efficiency • Water-cooling system for less maintenance • Indoor/outdoor configuration for greater flexibility • Inverter only and complete power station configuration offerings Advanced grid features GE has always been at the forefront of grid support features, and its converters are compliant with the most stringent codes in the world. Our long-term collaboration with utilities and regulatory bodies provides an understanding of utility needs that forms the basis of the advanced grid features present in the ProSolar inverter. Our solution ensures smooth integration of power produced into the grid and manages reactive power regulation at the grid connection point, meeting all the new BDEW (Bundesverband der Energie- und Wasserwirtschaft) grid requirements. This equipment can also manage battery storage. Solar SCADA Solar SCADA provides a broad set of intuitive tools for the operation and maintenance of solar plants. Our solar SCADA application is accessible from anywhere on the network. It can also be used remotely with a secure internet connection or telephone line. To address the ever-growing security requirements in SCADA systems, user access control is integrated into the entire system and provides an audit trail of all activity. Comprehensive production and maintenance reports are available to enhance the owner’s ability to drive productivity across all aspects of the plant operation.
