Huawei LUNA2000-7-E1 Battery Module – Smart String Energy Storage
The Huawei LUNA2000-7-E1 is a high-performance lithium-iron phosphate (LiFePO4) battery module designed for residential and small commercial energy storage systems. As part of the LUNA2000 Smart String Energy Storage System, it combines advanced technology, safety, and scalability to deliver reliable energy storage solutions for modern solar PV installations.
Flexible Capacity and Scalability
Each LUNA2000-7-E1 battery module offers 6.9 kWh capacity, with a maximum discharge and charge power of 3.5 kW. The modular design allows installers and system owners to scale easily:
- 1 module = 6.9 kWh
- 2 modules = 13.8 kWh
- 3 modules = 20.7 kWh per group
Up to 4 groups can be connected in parallel, achieving a maximum system capacity of 82.8 kWh when paired with compatible Huawei inverters. This scalability makes it suitable for both single-family homes and larger projects requiring higher storage capacity.
High Usable Energy
Thanks to its 100% depth of discharge (DoD) and built-in energy optimizer, the LUNA2000-7-E1 ensures that users can fully utilize stored energy without significant losses. The system is designed for long service life, ensuring return on investment and reliable operation throughout its lifecycle.
Safety and Reliability
Huawei integrates five layers of safety protection into the LUNA2000-7-E1:
- Cell-level: lithium-iron phosphate cells with high thermal stability
- Electrical-level: overvoltage, overcurrent, and short-circuit protection
- Structural-level: robust casing with IP66 protection rating
- Active protection: continuous monitoring of temperature and current
- Emergency protection: fast response to critical conditions
With certifications including CE, VDE2510-50, IEC62619, IEC 60730, UN38.3, ISO13849, REACH, and RoHS, the system meets stringent European and international standards.
Compact, Quiet, and Durable
Each LUNA2000-7-E1 module has dimensions of 590 × 255 × 360 mm and weighs 68 kg, making it compact enough for both floor-stand or wall-mount installation. The system is designed for indoor or outdoor use, with an operating temperature range of -20°C to +55°C and installation altitude up to 4,000 m.
The natural convection cooling system keeps the modules running silently, with a noise level below 29 dB, making it suitable for residential applications without disturbing daily life.
Seamless Integration
The LUNA2000-7-E1 is compatible with a wide range of Huawei SUN2000 inverters, including:
- SUN2000-3/4/5/6/8/10KTL-M1
- SUN2000-5/6/8/10/12K-MAP0
- SUN2000-12/15/17/20/25K-MB0
- SUN2000-2/3/3.68/4/4.6/5/6KTL-L1
- SUN5000-8/12K-MAP0 and SUN5000-17/25K-MB0
This ensures flexibility for both new installations and retrofit projects.
