Deye BOS-A LiFePO₄ HV 38.4V 200Ah Battery, 7.68 kWh — professional high-voltage module for backup power and energy storage systems

The Deye BOS-A battery module is a high-tech solution based on lithium iron phosphate chemistry, designed for reliable operation in large UPS systems, hybrid inverter complexes, and scalable power installations. With a capacity of 200 Ah, energy density of 7.68 kWh, and high-voltage operation, it provides stable power even during sharp peak loads, and is also characterized by a long service life and high efficiency.

Advantages of the Deye BOS-A battery

Safe and durable

Deye BOS-A uses LiFePO₄ cells, which are characterized by the highest thermal stability and safety among lithium batteries. This chemistry eliminates the risk of ignition, provides a long service life, and stable operation even in difficult conditions. The module has an official 10-year warranty and is equipped with protection against overcharge, deep discharge, overcurrent, and extreme temperatures, forming a reliable basis for professional backup power systems.

Intelligent management (BMS)

The built-in battery management system automatically controls charging and discharging, optimizes voltage balance between cells, and ensures correct interaction with the inverter. The BMS monitors parameters in real time, prevents overheating and overload, thereby extending battery life and maintaining maximum energy efficiency even in multi-module configurations.

High performance and efficient design

The module supports an output current of up to 160 A, which allows it to be used in high-load systems and with powerful inverters. The 3U rack-mount design allows easy integration of the module into standard server or power cabinets, and also provides for the connection of two DC inverter interfaces. This makes the system as convenient as possible to install and efficient to use.

Flexible and scalable

The Deye BOS-A design allows 7 to 21 modules to be connected in series, forming powerful high-voltage battery systems for 50–100 kW inverters. Thanks to this architecture, a total capacity of 54 to 161 kWh can be achieved, which allows for precise customization to the needs of the facility — from private energy systems to large-scale industrial solutions. Fast switching between grid and autonomous operation, which is less than 10 ms, makes the module an ideal component for UPS systems where absolute continuity of power supply is important.

The Deye BOS-A LiFePO₄ HV 38.4V 200Ah battery — is a highly reliable, durable, and scalable element of professional energy storage systems. It combines safe LiFePO₄ chemistry, intelligent management, high performance, and a flexible expansion architecture, allowing for the creation of both compact and large energy complexes. Thanks to fast switching in UPS mode, robust design, and the possibility of integration into industrial solutions, the battery provides stable power even in the most difficult conditions, forming the basis of a reliable and modern energy infrastructure.
