Deye: HV Bos-G Pro Battery Lithium Ion High Voltage 5.12Kwh 51.2V 100Ah (New Version)

Deye High Voltage (HV) BOS-G Pro 5.12kWh Lithium-Ion LiFePO₄ Battery (DEYE-BOS-G-PRO-5)

The Deye BOS-G Pro 5.12kWh High-Voltage Lithium-Ion Battery is a modular, scalable energy storage solution designed for advanced residential, commercial, and industrial solar installations. Built using high-quality Lithium Iron Phosphate (LiFePO₄) cells, this battery module delivers exceptional safety, long service life, and reliable performance in high-voltage battery systems.

With a nominal capacity of 5.12kWh per module, the BOS-G Pro series is engineered to form part of a larger high-voltage battery stack, allowing multiple modules to be combined to achieve the required system capacity. This modular architecture makes it ideal for projects where energy storage needs may grow over time, without requiring replacement of existing equipment.

Designed specifically for Deye BOS-G high-voltage systems, the BOS-G Pro 5.12kWh battery integrates seamlessly with Deye high-voltage inverters and the required BMU (Battery Management Unit). The intelligent system architecture ensures precise charge and discharge control, accurate state-of-charge reporting, and safe operation across the entire battery cluster.

Safety and durability are core features of the BOS-G Pro battery. The LiFePO₄ chemistry offers excellent thermal stability and resistance to overheating, while the system-level BMS provides protection against over-voltage, under-voltage, over-current, short circuits, and temperature extremes. This makes the battery well suited for demanding operating environments and frequent cycling.

The battery module features a robust, rack-mountable design, allowing neat and professional installation in plant rooms, battery cabinets, or containerised energy storage systems. Its high efficiency and long cycle life help reduce the total cost of ownership while delivering dependable energy storage for solar self-consumption, peak shaving, backup power, and grid-support applications.

Whether used in a commercial solar plant or a high-end residential installation, the Deye BOS-G Pro 5.12kWh HV Battery provides a future-ready, scalable foundation for modern high-voltage energy storage systems.
