- Maximum charging/discharging power of 21 kW
- LiFePO₄ technology - highest level of safety and durability
Product description
The Huawei LUNA2000-42-S1 system is a premium solution for large-scale photovoltaic installations that require significant energy storage capacity. The kit consists of two three-module towers (stacks), each of which offers a capacity of 20.7 kWh and works with its own LUNA2000-10KW-C1 power module. The entire system achieves an impressive total capacity of 41.4 kWh and a power output of 21 kW, ideal for residential, commercial and industrial applications.
The modular architecture with built-in energy optimizers ensures high energy efficiency, and the parallel connection makes it possible to operate the system in a flexible configuration. Quiet operation (less than 29 dB), no cables between modules and natural cooling make the LUNA2000-42-S1 a modern and practical solution for the most demanding users.
Safety and durability
The LUNA2000-42-S1 stack uses lithium-iron-phosphate (LiFePO₄) cell technology, which is known for its high chemical stability and resistance to overheating. Each stack has a five-layer protection system including cell levels, electrical, structural, active and emergency. The system complies with the requirements of international safety standards (IEC62619, UN38.3, CE, VDE2510-50, RoHS), which guarantees full reliability ekspLoatation under harsh conditions.
