Description
Deye 5.12 kWh LiFePO₄ BOS-G Pro Battery – the reliable energy storage solution for hybrid and commercial photovoltaic systems
The BOS-G Pro battery is part of Deye’s modular battery series, designed for rack mounting and direct integration into high-voltage (HV) systems. With a capacity of 5.12 kWh and LiFePO₄ technology, it offers high performance, chemical stability and a lifespan of over 6,000 cycles.
The compact, modular design allows the system to be scaled up to 81.92 kWh by connecting multiple modules in series (up to 16). The system is equipped with an intelligent BMS that monitors the voltage, current and temperature of each module, providing full protection against overloading, overvoltage and deep discharge.
Thanks to its native compatibility with Deye inverters, the BOS-G Pro battery is the ideal choice for commercial, industrial and residential applications requiring a safe, efficient and easily scalable system.
