Deye BOS-G40 Pro: High Voltage Energy Storage System (40.96 kWh)


The Deye BOS-G40 Pro is a state-of-the-art energy storage solution (ESS) designed for high-end residential and small commercial and industrial (C&I) applications. This high-voltage system features a modular 19-inch rack structure for easy installation and maintenance.





Technology and safety

The heart of the system is based on LiFePO4 (LFP) chemistry, renowned for its intrinsic safety, thermal stability and long service life.

  • Non-toxic materials: The entire module is environmentally friendly.
  • Sustainable performance: Over 6,000 cycles (at 25°C, 0.5C) up to an end-of-life (EOL) of 70%.
  • Optimised self-discharge: Can remain up to 6 months without recharging, with no memory effect.





Intelligent management (BMS)

Each system incorporates a sophisticated BMS (Battery Management System) ensuring total protection:

  • Integrated protections: Overcharge, excessive discharge, overcurrent, out-of-range temperatures.
  • Automatic balancing: Charge/discharge state management and cell-by-cell voltage and current balancing.
  • Simplified updates: Compatible with Deye inverters, updates via USB or remotely.

FAQ - Deye BOS-G40 Pro storage system

1. What is the actual storage capacity of the Deye BOS-G40 Pro? +
The system displays a total energy of 40.96 kWh. To preserve the longevity of the cells, the usable energy is 36.86 kWh (based on a DOD of 90%). This power reserve is ideal for ensuring self-consumption in large residential projects or small commercial buildings.
2. Why choose LiFePO4 (LFP) chemistry for this rack? +
LiFePO4 technology is the benchmark for safety in stationary storage. It offers exceptional thermal stability, is completely non-toxic and guarantees long-lasting performance with over 6,000 cycles, ensuring excellent efficiency throughout the system's lifetime.
3. Is this system scalable if my needs increase? +
Yes, modularity is one of the strengths of the BOS-G40 Pro. If your energy needs increase, you can connect up to 16 complete racks in parallel. This scalability allows you to adapt the storage capacity to the growth of your business or building.
4. What safety functions are managed by the BMS? +
The sophisticated BMS (Battery Management System) monitors each cell in real time. It provides comprehensive protection against overcharging, excessive discharge, overcurrent and out-of-range temperatures. It also manages automatic voltage balancing to maintain cluster efficiency.
5. Can I install the BOS-G40 Pro in an unheated room? +
The system is operational over a very wide temperature range, from -20°C to 55°C during discharge. However, to optimise service life and charge cycles, it is recommended that it be installed in a dry, temperate environment. Its protection rating is IP20, so it must be protected from water splashes.
6. What exactly does a complete BOS-G40 Pro unit contain? +
The unit consists of 8 BOS-G-Pack5.1 battery modules (5.12 kWh each), a BOS-G-PDU-2 high-voltage control unit responsible for cluster management, and a standard 19-inch rack (3U-LRACK) for clean and robust integration.
7. How long is the manufacturer's warranty? +
To protect your investment in self-consumption, Deye offers a 10-year manufacturer's warranty on this system. This warranty highlights the reliability of the high-voltage system and the robustness of its modular design.
