The Huawei LUNA2000-215-2S10 Smart String ESS energy storage system is a high-efficiency industrial-grade energy storage solution designed for commercial and industrial solar power plants. The system provides reliable energy storage and management, helping to optimize power consumption, improve solar generation efficiency, and provide backup power. The system is built using lithium iron phosphate (LFP) batteries, which are characterized by high safety, a long service life, and stable operation over a wide temperature range. The system's nominal capacity is 215 kWh, and the maximum cycle efficiency reaches 91.3%, ensuring the efficient use of stored energy. The Huawei LUNA2000-215-2S10 is equipped with an intelligent battery management system and a hybrid cooling system, ensuring stable equipment operation and optimal temperature conditions. The system supports automatic cell balancing and automatic state-of-charge (SOC) calibration, increasing the longevity of the battery modules. The integrated protection system includes insulation monitoring, short-circuit, overload, and overvoltage protection. A fire safety system with directional gas exhaust, an overhead explosion damper, and an aerosol fire suppression system is also implemented. The system is equipped with a PCS2000-108K-MB1 power converter with a rated output of 108 kW and supports three-phase grid connection (380/400/415 V, 50/60 Hz). Ethernet or fiber optic interfaces, as well as the Modbus TCP protocol, are used for communication and integration. The Huawei LUNA2000-215-2S10 is designed for use in commercial and industrial projects: in enterprises, business centers, infrastructure facilities, and large solar power plants, where efficient energy management, load smoothing, and increased energy independence are required.
