Efficient energy storage for commercial and residential applications
The BOS-G 35 PRO set is based on high-quality LiFePO4 cells, which are known for their stability, safety, and long service life. With a system voltage of 358.4 volts and usable energy content of over 32 kWh, the system is ideal for optimising self-consumption, peak shaving, and backup applications.
Scalable storage solution with system
Thanks to its modular design, the BOS-G 35 PRO system can be flexibly expanded. The combination of several battery modules enables customised adaptation to growing energy requirements. The system can operate up to 16 racks in parallel and supports AC-parallel operation of up to 10 inverters.
Intelligent energy management
The integrated BMS (Battery Management System) protects each battery cell from critical conditions such as overcharging, deep discharge, or overheating. It automatically takes over cell balancing and ensures an even load on all modules.

FAQs about the Deye BOS-G 35 PRO high-voltage storage set
What capacity and cycle life does the system offer?
The BOS‑G 35 PRO delivers gross 35.84 kWh and net approx. 32.25 kWh usable energy at 90 % DoD. The battery achieves ≥ 6000 charging cycles (0.5 C, up to 70 % DoD at 25 °C) with a 10-year warranty.
In which temperature range can the BOS‑G 35 PRO be operated?
Operation is possible from −20 °C to +55 °C. The charging circuit operates between 0 °C and +55 °C, discharge possible from −20 °C.
What protective functions does the BMS offer?
The integrated BMS actively monitors and protects against over-/undercharge, overcurrent, short circuit as well as temperature extremes, carries out cell balancing, and controls charging and voltage levels.
Do I need special rooms or fire protection?
The EU version stipulates that installation is only permitted in fireproof rooms (fire protection T60) is permitted. The system is also suitable for indoor locations with IP20 protection only.
Can the system be expanded?
Yes, thanks to the modular design, several BOS‑G modules can be operated in parallel. In the EU up to 16 battery racks and up to 10 inverters in AC parallel operation can be connected.Scope of delivery Deye BOS-G35 PRO high-voltage storage set (35.84 kWh) with rack system:
