Huawei LUNA2000-7-E1 - Intelligent energy storage system
Huawei LUNA2000-7-E1 is a state-of-the-art lithium-iron-phosphate (LiFePO₄) battery module with a capacity of 6.9 kWh, designed for use in Huawei Smart String Energy Storage System. The device features high efficiency, flexible expansion up to 82.8 kWh and full integration with Huawei SUN2000 inverters. Thanks to its modular architecture and built-in energy optimizer, it ensures maximum utilization of stored energy and the highest level of security expLoatation.
- Usable capacity of 6.9 kWh
- Modular architecture with built-in energy optimizer
- 100% depth of discharge (DoD)
- Five-layer protection system and LiFePO₄ technology
- Operating temperature range from -20°C to +55°C
Product description
The Huawei LUNA2000-7-E1 is the primary component of the LUNA2000 series energy storage system, which can be scaled by combining up to three modules in a group (maximum 20.7 kWh). The system can be further expanded to four groups (82.8 kWh total) when combined with a Huawei inverter. Each module includes an integrated energy optimizer, ensuring balancing of energy levels between modules and increasing the lifetime of the entire system. The design allows for easy installation with wireless connections between modules.
Security and reliability
LUNA2000-7-E1 is designed according to a five-layer protection system: from the cell level, electrical and structural protection, to active and emergency safety mechanisms. LiFePO₄ technology ensures thermal stability and resistance to overheating. The system also features low noise levels (<29 dB), natural cooling, and the ability to operate outdoors thanks to its IP66:contentReference[oaicite:0]{index=0} rating.
