Deye 5.12kWh BOS-G Pro LiFePo4 Battery, Deye

Deye 5.12 kWh BOS-G Pro LiFePO₄ battery – the reliable energy storage solution for hybrid and commercial photovoltaic systems

Battery BOS-G Pro is part of the modular battery series Deye, designed for rack mounting and direct integration into high voltage (HV) systems. With a capacity of 5.12 kWh and technology LiFePO₄, offers high performance, chemical stability, and a service life of over 6,000 cycles.

The compact and modular design allows the system to be expanded up to 81.92 kWh, by connecting several modules in series (up to 16). The system is equipped with Intelligent BMS which monitors the voltage, current, and temperature of each module, providing complete protection against overloads, overvoltage, and deep discharge.

Thanks to native compatibility with Deye inverters, The BOS-G Pro battery is the ideal choice for commercial, industrial, and residential applications that require a safe, efficient, and easily scalable system.
