HLH-PU 1.2MWh Containerized Battery Storage System Modular All-in-One BESS for Industrial Micro-grids

The Energy Storage Integrated Cabinet Series – 1.2MWh is designed for large-scale centralized energy storage projects that require high capacity, long operational life, and intelligent system-level control. This solution is positioned for utility-scale and centralized deployments where energy stability, grid interaction, and efficient power management are critical.

The system is built with all-new Grade A LFP battery cells, providing strong electrochemical stability and consistent performance over long-term operation. With a cycle life of up to 8000 cycles, the cabinet supports intensive daily charge and discharge requirements typical of large-scale energy storage systems. This makes it suitable for applications such as renewable energy integration, grid balancing, peak regulation, and long-duration energy dispatch.

The integrated cabinet supports both on-grid and off-grid operating modes, allowing flexible participation in grid services while maintaining independent power supply capability when required. Designed with an IP55 enclosure, the system can be installed outdoors and withstand harsh environmental conditions, including dust, humidity, and temperature variation. Compliance with CE and UN38.3 standards supports international deployment and safe transportation for large-scale projects.
