Product description
Huawei LUNA2000-28-S1 is a set of two LUNA2000-14-S1 systems connected in parallel to form a single system with a total capacity of 27.6 kWh. Each stack contains two 6.9 kWh battery modules, working together with a dedicated base and power module. This allows the kit to deliver up to 14 kW of charge and discharge power, making it ideal for homes and small businesses with high energy demands.
The kit comes as a compLete solution with factory wiring and mounting components, reducing installation time and minimizing the risk of errors. Modular architecture with built-in energy optimizers ensures independent operation of each section, maximizing efficiency and operational safety.
Safety and reliability
The LUNA2000-28-S1 system is based on lithium-iron-phosphate (LiFePO₄) cell technology, offering exceptional thermal stability and resistance to overheating. A five-layer protection system (cell level, electrical, structural, active and emergency) provides full operational protection. IP66 rating allows installation in any environment - indoors or outdoors.
