Product information
The Deye BOS-B241.1 kWh PRO-A3 is a highly efficient, three-phase high-voltage battery storage system of the very highest calibre, developed specifically for the most demanding large-scale projects in the commercial and industrial (C&I) sectors. It replaces rigid and difficult-to-scale legacy systems with a highly integrated, turnkey cabinet solution offering maximum energy density, whilst providing intelligent functions to optimise industrial energy flow.
With its sophisticated design, the BOS-B system is not just a passive energy storage solution, but serves as a future-proof foundation for your company’s energy management (Industrial Storage Hub). It supports seamless integration with high-performance Deye hybrid inverters (such as the SUN-125K series) and ensures that your business retains maximum control over its energy costs at all times.
Highlights at a glance
- Maximum industrial capacity: Offers a massive 241.1 kWh of usable energy in a single, optimized cabinet system, based on the safest lithium iron phosphate (LiFePO4) technology.
- High-voltage efficiency: The series connection of the modules ensures an extremely high system voltage, which minimises conversion losses when used in conjunction with large inverters and enables a massive supply of energy.
- Excellent cycle stability: With over 6,000 charge cycles, the system guarantees an extremely long service life and maximum investment security, even with daily, intensive use.
- Intelligent Master BMS: The integrated control system in the cabinet continuously monitors cell voltages, temperatures and currents, and ensures fully automatic cell balancing.
- Safety functions: Multi-stage protection mechanisms, including automatic shutdown in the event of overcurrent, overvoltage or thermal irregularities, guarantee worry-free operation around the clock.
- Flexible scalability: Multiple cabinet units can be easily connected in parallel to flexibly scale the total capacity alongside your business growth.
Areas of application
The Deye BOS-B241.1 kWh PRO-A3 is the perfect addition to commercial PV systems and industrial infrastructure:
- Peak shaving: Reduction in grid usage charges through the targeted absorption of expensive electricity peaks in the industrial production process.
- Optimisation of self-consumption: Efficient temporary storage of solar power from large industrial rooftops that is unused during the day, to provide self-sufficient power for operations in the evening and at night.
- Emergency power & backup systems: Reliable protection of critical loads (such as IT infrastructure, cooling systems or sensitive production lines) in the event of power failures.
Installation & safety instructions
- Inverter compatibility: The system is designed as a high-voltage storage solution and must be operated with compatible Deye three-phase high-voltage hybrid inverters.
- Installation & environment: Due to the extremely high system weight, the cabinet solution should be installed on a specially reinforced, level base (foundation) and in a well-ventilated, temperature-controlled indoor space.
- Installation by qualified personnel: Due to the high-voltage direct current (DC) environment and the industrial power ratings, installation, cabling and commissioning must be carried out exclusively by certified qualified electricians.

FAQs on the Deye BOS-B241.1 kWh PRO-A3
Can the 241.1 kWh capacity be expanded at a later date?
- Yes. The system has a modular design. To increase the total capacity, several of these cabinet units can be connected in parallel, enabling storage capacities in the megawatt range to be achieved.
Is the master control unit (BMS) already integrated into the cabinet?
- Yes. The system is supplied as a turnkey cabinet solution, in which both the individual battery modules and the central cluster control unit (high-voltage BMS) are integrated into the rack, ready for operation.
What advantages does LiFePO4 technology offer in industrial applications?
- Maximum safety and durability. Unlike conventional lithium-ion batteries, lithium iron phosphate cells are extremely thermally stable, non-flammable and offer a significantly higher number of charge cycles, even under heavy use.
Does the system support control via an external energy management system (EMS)?
- Yes. Via the integrated communication interfaces, the storage system can be seamlessly connected to higher-level commercial energy management systems (EMS) to implement complex charging and discharging strategies.
