The modular architecture and flexible design of A123’s GSS optimize performance and increases system efficiency to increase the stability and reliability of the grid while enabling the seamless integration of renewable power sources. A123’s fully integrated, grid-ready GSS are designed as complete solutions capable of achieving greater than 90% AC to DC to AC roundtrip efficiency. Each GSS consists of a Grid Battery System (GBS), AEROS software and a Power Conversion System.

The GBS is based on modular, rack-integrated energy storage units which serve as the building blocks for configurable high-rage and long-duration systems designed to meet application-specific requirements. A123’s GBSs are available with onboard touch screen control panels, heat and smoke detection, and fire suppression to provide customers with the necessary infrastructure to integrate the GSS with their existing systems. In addition to A123’s standard containerized GBS units available in 20-foot, 40-foot and 53-foot lengths, A123’s rack-integrated battery systems can be deployed in buildings or other custom enclosures.

In addition to the Grid Battery System, the GSS feature A123’s Energy Response Operating System (AEROS), the company’s proprietary software designed to deliver full command and control functionality for seamless integration with existing utility systems. AEROS is designed to increase the efficiency and optimize the performance of the energy storage system by enabling automated command and control with built-in secure protocols, real time reporting of systems capabilities and performance, millisecond response times and multiple operating modes to optimize customers’ application requirements. A123’s GSS are also equipped with high-efficiency power inverters that convert DC to AC and AC to DC to provide real and reactive power as well as bidirectional energy flow to the grid.
