Deye BOS-G-PRO-PDU-2 High Voltage Battery Control Module for BOS-G Pro Energy Storage Systems
The Deye BOS-G-PRO-PDU-2 is a high-voltage battery cluster control module designed specifically for Deye BOS-G Pro series lithium energy storage systems. Engineered for commercial and industrial (C&I) solar PV applications, this professional-grade battery PDU (Power Distribution Unit) ensures safe, stable, and scalable operation of large-capacity energy storage systems integrated with high-power solar inverters.
Central Control for Modular HV Energy Storage
The BOS-G-PRO-PDU-2 acts as the central management and connection unit between multiple BOS-G Pack 5.1 lithium battery modules and the external PCS or hybrid inverter. It supports a wide operating voltage range from 200 to 1000 VDC, enabling flexible system design for small to mid-scale C&I energy storage projects. With a nominal charge/discharge current of 100 A and maximum current of 120 A, it is optimized for high-power, continuous operation in demanding environments.
Safe and Reliable LiFePO₄ System Architecture
Designed to work with LiFePO₄ (LFP) battery chemistry, the BOS-G-PRO-PDU-2 benefits from the inherent safety, thermal stability, and long cycle life of lithium iron phosphate technology. Combined with the intelligent BMS architecture of the BOS-G Pro system, it provides comprehensive protection against over-voltage, over-current, short circuit, and temperature extremes. This makes it a reliable backbone for solar battery storage, peak shaving, self-consumption, and backup power systems.
Scalable Design for Commercial Solar Projects
The BOS-G-PRO-PDU-2 enables parallel connection of up to 16 battery racks and 16 battery clusters, supporting total system capacities from 35 kWh up to 87 kWh per rack and significantly beyond in multi-rack installations. It also supports up to 10 inverters operating in AC parallel, making it suitable for large hybrid solar systems and distributed energy storage architectures commonly used by EPCs and commercial installers.
Installer-Friendly Rack-Mounted Format
Housed in a compact 19-inch rack-mount enclosure, the BOS-G-PRO-PDU-2 measures 440 × 570 × 150 mm and weighs approximately 19 kg, allowing straightforward installation in standard battery racks. The unit features CAN2.0 and RS485 communication ports, ensuring seamless communication with Deye inverters and battery modules. An IP20 protection rating makes it suitable for indoor technical rooms and energy storage cabinets.
Ideal for Professional Solar PV and Energy Storage Systems
The Deye BOS-G-PRO-PDU-2 is an essential component for any BOS-G Pro high-voltage battery system, delivering centralized control, electrical safety, and scalable performance. It is the preferred solution for solar PV suppliers, solar distributors, and energy storage wholesalers delivering reliable, future-proof commercial solar battery systems across Europe.
