Deye AI-W5.1-B LV battery

Engineered for floor-mounted stacking installation, the AI-W5.1-B allows users to easily expand system capacity as energy demand grows. Its space-efficient structure (720 × 255 × 300 mm, approx. 53 kg) makes it especially suitable for modular indoor or protected outdoor deployment. After stacking, the system achieves an IP65 protection level, ensuring strong resistance against dust and moisture for enhanced installation flexibility.

The battery operates reliably across a wide temperature range (0°C–55°C charging, −20°C–55°C discharging), with an optional heating function available for colder environments. Integrated LED status indicators clearly display operating, warning, and protection conditions for convenient monitoring. 

Supporting CAN2.0 and RS485 communication, the AI-W5.1-B integrates smoothly with leading hybrid inverters and smart energy platforms. With extensive certifications including IEC62619, VDE2510-50, UL1973, UL9540A, CEC, FCC, and CE, plus a 10-year warranty and 16 MWh energy throughput, it is ideal for modular residential storage, backup support systems, and expandable PV energy solutions.
