Deye BOS-G PRO Battery Kit, 40 kWh

The Deye BOS-G 40 kWh battery kit is a modern high-voltage energy storage system created to provide a stable and uninterrupted power supply in conditions of an unstable electricity grid. It is ideal for private houses, businesses and commercial facilities.

The system is built on modular batteries of the BOS-G-Pack5.1 series, which makes it possible to configure the capacity flexibly to suit the user's needs.

• Total capacity: ~40 kWh
• System type: high-voltage (HV)
• Battery chemistry: LiFePO₄
• Scalability: the system can be expanded

The batteries use lithium iron phosphate technology (LiFePO₄), which provides:

• more than 6000 charge/discharge cycles
• high thermal stability
• no risk of overheating or ignition
• environmental friendliness (cobalt-free)

The system comes with a battery management unit (BMS) that:

• controls charging and discharging
• balances the voltage between modules
• protects against overloads and short circuits
• ensures stable operation of the entire system

Key advantages

• High capacity — optimal for backup power and off-grid systems
• Flexible modular structure — the option of gradual expansion
• Compatibility with hybrid and grid-tied inverters
• Reliability — stable operation even at peak loads
• Energy efficiency — minimal energy losses

Where it is used

• private houses and country homes
• offices and commercial premises
• small production facilities
• backup power systems
• solar power plants

The Deye BOS-G 40 kWh battery kit is a versatile solution for those who strive for stability and independence from the grid. Thanks to its high capacity, durability and modern control technologies, the system makes it possible to use energy efficiently and reduce electricity costs.
