Deye 5.12kwh 48V high voltage Lithium ion battery BOS-W

The Deye BOS-W 5.12kWh 48V High Voltage Lithium-Ion Battery is a premium energy storage solution designed to meet the demands of today’s solar energy systems. Using LiFePO₄ chemistry, it ensures superior safety, long service life, and excellent thermal stability compared to other lithium technologies.

This battery integrates a smart BMS that monitors cell voltage, temperature, and current to prevent overcharging, over-discharging, and short circuits. It is modular and scalable, allowing up to several units to be connected in series to achieve higher voltages — perfect for high-voltage solar setups when paired with the Deye BOS-W-PDU-2 Cluster Control Box.

Ideal for residential solar storage, commercial energy systems, and backup applications, the Deye BOS-W battery delivers stable power, high round-trip efficiency, and easy integration with Deye hybrid inverters.
