TIGER MEGA series Outdoor Liquid-Cooled Energy Storage container is designed for VRE power generation storage, grid load reduction, peak shaving and valley filling in commercial and industrial sectors, micro-grids, and intelligent power dispatch. It features high safety with long-cycle life battery cells, full certifications including IP55 protection, and multiple safety layers, meeting stringent North American standards UL9540A and NFPA 855. The system prevents battery thermal runaway, has four-level fire control, and ensures no circulating current in single clusters or short circuits between clusters. It offers easy configuration with the ability to add machines in parallel at any time, integrated transportation, and easy installation, along with flexible site layout and modular design for convenient maintenance and upgrades. With battery cell efficiency greater than 95.5% and system efficiency over 90%, it maintains 70% energy retention even after 10 years (two charges and discharges per day). The advanced EMS energy management cloud platform provides millisecond-level data monitoring, dynamic management, real-time information exchange, and risk prediction, with multi-platform, high-concurrency, and visualization capabilities. The system boasts a long lifespan with up to 8,000 battery cycles and a 15-year design lifespan under standard conditions, while liquid cooling extends battery life by 30%. Additionally, it supports both grid-connected and off-grid parallel operation with anti-backflow capabilities, allowing for easy expansion by increasing the number of parallel machines at any time.
