GRES (Grid Renewable Energy Storage Power Supply) Static Generator is an intelligent and modular power supply system, integrating lithium battery and Multi-functional Power Conversion System. (MPCs). The main components,lithium battery, bidirectional DC / AC converter, bidirectional DC / DC converter, Static Transfer Switch STS and monitoring unit PMS,can be combined in various ways to meet the needs of different scenes.
GRES can be equipped with photovoltaic MPPT to build a microgrid, and can also be equipped with STS static transfer switch to realize seamless switching between on and off the grid. The system can use lithium battery to intelligently combine photovoltaic, utility grid, diesel generator and load together, realize multi energy complementary and strategic intelligent power consumption, and provide users with high-quality energy consumption service with high economy, high reliability and high security.
