Deye AI-W5.1-B 15 kWh Low-Voltage Battery Kit

Deye AI-W5.1-B (15.36 kWh) is a ready-made energy storage solution that combines three LiFePO₄ modules of 5.12 kWh each. As a result, you get a powerful energy storage system of more than 15 kWh — the ideal option for backup power, off-grid systems or for reducing dependence on the grid.

The system scales easily according to your needs. The basic set can be expanded to 6 modules, which makes it possible to increase capacity to more than 30 kWh. This makes it a versatile choice for private houses as well as for businesses or agricultural facilities.

Each module is equipped with a built-in BMS that:

• monitors temperature, current and voltage
• provides cell balancing
• protects against overloads, overheating and deep discharge

Thanks to automatic synchronization, the modules work as a single system, distributing the load evenly and optimizing energy consumption.

The set integrates perfectly with Deye hybrid inverters via CAN and RS485 interfaces. This ensures stable operation, accurate monitoring and efficient management of the entire energy system.

Reliable LiFePO₄ technology

The use of lithium iron phosphate chemistry guarantees:

• more than 6000 charge/discharge cycles (up to 90% DoD)
• high thermal stability and safety
• minimal capacity degradation
• a service life of more than 15 years

The sturdy metal housing makes it possible to install the system either on the floor or on the wall. The compact format saves space and simplifies integration into any room.

Deye AI-W5.1-B (15.36 kWh) is a modern solution for those who want a stable, safe and durable source of energy. The system efficiently accumulates and stores electricity, supplying you with power in any conditions — at home, in business or at remote sites.
