Deye AI-W5.1-B 25 kWh Low-Voltage Battery Kit

The Deye AI-W5.1-B battery system is an innovative solution for efficient electricity storage in residential and commercial environments. Thanks to its modular design and safe LiFePO₄ chemistry, it delivers a stable power supply, high performance and full adaptability to the user’s needs.

The system is ideal for off-grid or hybrid energy complexes, helping to reduce dependence on the utility grid and optimise electricity costs.

The modular architecture makes it easy to scale the system according to consumption. The 25 kWh configuration provides an optimal balance between capacity and efficiency, and if required it can be expanded to a significantly larger volume.

This solution is especially relevant for those who plan to build or upgrade a solar power plant and want to obtain the maximum return from the energy produced.

The system is based on lithium iron phosphate technology (LiFePO₄), which is notable for its high thermal stability and long service life. It:

• contains no cobalt
• is resistant to overheating
• delivers thousands of charging cycles

The intelligent battery management system (BMS) constantly monitors the battery status, protecting it from overvoltage, overload and short circuits.

The system has an IP65 protection rating and operates stably across a wide temperature range — from -20°C to +55°C. Passive cooling reduces component wear and increases overall reliability.

This allows the battery to be used both indoors and in outdoor installations.

Deye AI-W5.1-B supports the combination of a large number of modules into a single system. This opens up the possibility of creating energy storage installations with a capacity of up to 184 kWh, suitable for private homes as well as for businesses and industrial facilities.

The system is designed with ease of operation in mind:

• automatic module connection
• remote monitoring
• software update capability

The compact design allows the battery to be installed either on the floor or on a wall without complex mounting work.

Deye AI-W5.1-B 25 kWh is a versatile solution for those who strive for energy independence and stability. It combines safety, scalability and modern technology, ensuring efficient energy storage and use in any conditions.
