Efficient energy storage for commercial and domestic applications

The BOS-G 35 PRO Set is based on high-quality LiFePO4 cells, which are renowned for their stability, safety and long service life. With a system voltage of 358.4 volts and a usable energy capacity of over 32 kWh, the system is ideally suited for optimising self-consumption, peak load shaving and backup applications.

A scalable storage solution with a system

Thanks to its modular design, the BOS-G 35 PRO system can be flexibly expanded. Combining multiple battery modules allows for customisation to meet growing energy requirements. The system can operate up to 16 racks in parallel and supports AC parallel operation of up to 10 inverters.

Smart energy management

The integrated BMS (Battery Management System) protects each battery cell from critical conditions such as overcharging, deep discharge or overheating. It automatically performs cell balancing and ensures that the load is distributed evenly across all modules.

Who is the Deye BOS-G 35 PRO high-voltage storage set suitable for?

This high-voltage storage system is ideal for:

• Operators of photovoltaic systems with medium to high energy requirements
• Businesses seeking to reduce the load on the mains supply or requiring backup solutions
• Homeowners who want to increase self-consumption and independence
• Projects requiring high scalability and compatibility with Deye systems

FAQs on 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 a gross 35.84 kWh and approx. net 32.25 kWh usable energy at 90% DoD. The battery achieves ≥ 6,000 charge cycles (0.5 C, up to 70 per cent DoD at 25 °C) with a 10-year warranty.

Within what temperature range can the BOS‑G 35 PRO be operated?

Operation is possible from −20 °C to +55 °C. The charging circuit runs between 0 °C and +55 °C, with discharge possible from as low as −20 °C.

What protection functions does the BMS offer?

The integrated BMS actively monitors and protects against Over- or under-charging, overcurrent, short circuits and extreme temperatures, performs cell balancing and controls the charging process and voltage level.

Do I need special rooms or fire safety measures?

The EU version stipulates that installation may only take place in fire-resistant rooms (fire protection T60) is permitted. Furthermore, the system is only intended for Indoor use with protection class IP20 suitable.

Can the system be expanded?
