GSL ENERGY flexible energy storage systems are designed for indoor and outdoor installation. The containers are built for both small-scale and large-scale energy storage systems, up to multi-megawatt systems. All our systems use the same building block structure of a GSL ENERGY partnered with its own inverter, a redundant architecture that minimizes the possibility of a single point of failure in the system and maximizes reliability. Large-scale systems use a Multi-Tower Power Source Controller to manage the cells across the entire system.
