Description

The 500kW/1MWh C&I medium-sized energy storage cabinet system is an energy storage system applied in industrial and commercial scenarios. It can be directly connected to the AC low- voltage side to provide reliable power support for various equipment and systems.

The energy storage system utilizes lithium iron phosphate batteries, offering high energy density and an extended cycle life. Housed in an outdoor cabinet, the system features a scalable design that allows for flexible expansion and easy maintenance. A local data monitoring module is integrated within the cabinet, enabling comprehensive management of all internal components. This setup supports both independent operation and integration with a station-level control system for coordinated multi-unit functionality. By continuously tracking equipment status and logging operational data, the system enables early fault detection and rapid troubleshooting. An intelligent temperature control mechanism further enhances system efficiency and prolongs battery cycle life. The modular architecture facilitates straightforward system scaling and adaptable deployment.
