Deye BOS-G 85 PRO High Voltage Storage Set 87.04 kWh

Deye BOS-G85 Pro LiFePO₄ High-Voltage Battery System – 87.04 kWh Capacity for Maximum Energy Independence

Rethinking Efficient Energy Storage

The BOS-G85 Pro from Deye revolutionizes energy storage with a sophisticated high-voltage design based on 17 powerful LiFePO₄ battery modules. With an installed capacity of over 87 kWh, this system provides enough energy for demanding applications – whether at home, in commercial settings, or in industry.

How does the BOS-G85 Pro work?

The 17 individual battery modules are mounted in two standardized 19-inch racks and connected via a central control unit – the BOS-G-PDU-2. This unit handles communication with the inverter and ensures intelligent distribution of charging and discharging currents. Thanks to the integrated BMS (Battery Management System), each cell is monitored, protected, and optimized – fully automatically.

What makes the BOS-G85 Pro so special?

• Scalability: The modular design allows for expansion with additional units at any time – perfect for growing energy needs.
• Durability: With over 6000 charge cycles at consistent performance, the system is among the most durable in its class.
• Safety: LiFePO₄ is not only thermally stable and fire-safe but also completely non-toxic and low-maintenance.
• Smart Control: The system can be updated and monitored remotely – ideal for modern smart home or Industry 4.0 applications.

Who is the BOS-G85 Pro suitable for?

The system is ideal for users who:

• wish to maximize their independence from the power grid,
• are looking for an emergency power solution for critical infrastructures,
• want to efficiently store and use PV systems,
• need a durable, sustainable, and scalable energy storage solution.

Smart. Strong. Future-Proof.

With the BOS-G85 Pro, you bring a future-ready high-performance battery system into your home, convincing with intelligent control, massive capacity, and absolute safety. It integrates effortlessly into existing systems and is ready for the demands of tomorrow.
