Product description
The LUNA2000-14-S1 system is part of the Huawei Smart String Energy Storage series, based on a flexible modular architecture. It consists of one power module and two battery modules with a total capacity of 13.8 kWh. It provides a maximum output of 7 kW for charging and discharging, enabling efficient energy management for medium-power photovoltaic installations.
The system is easy to install with wireless connections between modules, and the compact design allows both floor and wall mounting. Natural cooling ensures quiet operation with noise emissions of less than 29 dB.
Safety and technology
LUNA2000-14-S1 uses safe lithium-iron-phosphate (LiFePO₄) cells for long life and stable operation. The system features five-layer protection (at the cell, electrical and structural levels), ensuring safe use even in harsh conditions. In addition, the full depth of discharge (100% DOD) increases energy efficiency.
