Deye BOS-A – 53.76 kWh high-voltage battery storage for commercial and industrial use

The Deye BOS-A System in the 53.76 kWh configuration is a high-performance, modular high-voltage storage solution, specially developed for the requirements of commercial enterprises, industrial plants and larger PV projects. Based on the robust BOS-A battery module (7.68 kWh per unit), this system provides a reliable energy reserve for emergency power supply and the optimisation of self-consumption from renewable energies.

By using safe lithium iron phosphate technology (LiFePO4) and an intelligent, cloud-based management system, the storage provides maximum reliability and efficiency. The system is optimised for installation in rack environments and enables quick assembly as well as straightforward maintenance in professional contexts.

Highlights at a glance

• High capacity: With 53.76 kWh (achieved by 7 modules connected in series), the system provides powerful reserves for commercial applications, emergency power solutions and load management.
• Safe LiFePO4 chemistry: The cobalt-free cell chemistry ensures maximum thermal stability and an extremely long service life of over 6000 cycles.
• Intelligent cloud management: Real-time monitoring of energy usage and battery status via the Deye Cloud platform to optimise operating costs.
• High-voltage efficiency: The serial connection of the modules ensures a high system voltage, minimising conversion losses and improving overall system efficiency.
• Effortless installation: The embedded design and a module weight of approx. 70 kg enable a structured set-up in standard rack systems.
• Robust industrial design: High protection standards and resistance against various environmental conditions enable long-term use in technical rooms.
• Comprehensive warranty: 10-year manufacturer's warranty and a full replacement guarantee for up to 6000 cycles provide long-term investment security.

Areas of application

The 53.76 kWh version of the BOS-A is the ideal solution for demanding projects in commercial and industrial environments:

• Industrial & commercial enterprises
  • Ensuring an uninterruptible power supply (UPS) for critical machines and reducing load peaks during ongoing operations.
• Larger photovoltaic systems
  • Efficient interim storage of solar power to maximise the self-consumption rate in office buildings, agricultural businesses or smaller production sites.
• Neighbourhood storage
  • Central storage solution for residential complexes or municipal energy projects for the shared use of solar power.

Installation & Safety Instructions

• Rack configuration
  • The system achieves its capacity through the series connection of 7 battery modules per rack. Ensure that they are properly secured mechanically in the control cabinet.
• Safety management
  • The integrated Smart-BMS protects each module individually against overcharging, deep discharge and short-circuiting. Communication takes place seamlessly via CAN 2.0.
• Static & weight
  • A fully equipped 53.76 kWh rack weighs approx. 500–600 kg. Ensure that the foundation at the installation location is designed for these loads.

FAQs on the Deye BOS-A 53.76 kWh storage

Can the 53.76 kWh system be further expanded?

Yes. Several racks can be connected in parallel to achieve larger total capacities for commercial or industrial applications. The modular design allows the system to be precisely adapted to growing energy demands.

How does the emergency power supply work at this scale?

Automatic and powerful. In combination with a suitable Deye high-voltage inverter, the system can switch to battery operation within milliseconds in the event of a grid failure and continue to reliably supply important loads.

Why is the BMS so important in this system?

For balance and safety. In a series connection of 7 modules, the BMS ensures that all cells are charged and discharged evenly. This prevents individual modules from aging prematurely and maximises the usable energy of the entire storage block.

Is the system maintenance-intensive?

No. Thanks to the fanless design of the battery modules and the robust LiFePO4 technology, the system is almost maintenance-free. Remote monitoring via the cloud also makes it possible to detect irregularities early before they become a problem.
