Applications

The Deye BOS-B can be considered for:

• Commercial buildings and business facilities.
• Industrial facilities with high electricity demand.
• Solar photovoltaic energy storage.
• Peak-demand management and load shifting.
• Time-of-use energy management.
• Backup power systems designed with compatible PCS and switching equipment.
• Factories, warehouses and production facilities.
• Large hotels, lodges and hospitality properties.
• Commercial sites using solar PV and generators.
• Large energy storage projects requiring modular expansion.

The system must be designed according to the facility’s energy consumption, required backup duration, load profile, available solar generation and power conversion equipment.

Compatibility

The Deye BOS-B is a commercial and industrial battery system. It is not a standard residential battery that can be connected directly to any hybrid inverter.

Before specifying the system, verify:

• Compatibility with the selected Deye PCS or approved inverter configuration.
• Battery cluster voltage and charge/discharge current limits.
• The number of modules and clusters permitted by the system design.
• Communication compatibility between the battery BMS, PCS and energy management system.
• Required MPPT, STS, protection and auxiliary power equipment.
• Installation space, floor loading, ventilation and fire safety requirements.
• Applicable electrical regulations and commissioning requirements.

The BOS-B battery enclosure is rated IP20. The battery installation must therefore be designed for an appropriate protected environment and must follow the manufacturer’s installation and safety instructions.
