Deye BOS-A – 100 kWh high-voltage battery storage system for commercial and industrial applications

The Deye BOS-A system in the 100 kWh configuration is a powerful, modular high-voltage storage solution specially developed for the requirements of commercial enterprises, industrial facilities and large PV projects. Based on the robust BOS-A battery module (7.68 kWh per unit), this system provides a massive energy reserve for emergency power supply and optimisation of self-consumption from renewable energy sources.

By using safe lithium iron phosphate technology (LiFePO4) and an intelligent cloud-based management system, the storage guarantees maximum reliability and efficiency. The system is optimised for installation in rack environments and enables rapid assembly and uncomplicated maintenance in professional settings.

Highlights at a glance

• Massive capacity: With around 100 kWh (achieved by 13 modules in series), the system provides huge reserves for industrial applications and peak shaving.
• 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 use and battery status via the Deye cloud platform for optimising operating costs.
• High-voltage efficiency: The series connection of the modules ensures a high system voltage, which minimises conversion losses and increases the efficiency to over 90%.
• Effortless installation: The embedded design and a module weight of approx. 70 kg enable structured assembly in standard rack systems.
• Robust industrial design: High IP protection rating and resistance to different environmental conditions for sustained use in technical rooms.
• Comprehensive warranty: 10-year manufacturer's warranty and full replacement guarantee for up to 6000 usage cycles provide long-term investment security.

Areas of application

The 100 kWh version of the BOS-A is the ideal solution for demanding large-scale projects:

• Industrial & commercial enterprises
  • Ensures an uninterruptible power supply (UPS) for critical machines and reduces costly peak loads.
• Large photovoltaic plants
  • Efficient intermediate storage of solar power to maximise self-sufficiency in office buildings or farms.
• Neighbourhood storage
  • Centralised storage solution for residential complexes or municipal energy projects for shared solar power use.

Assembly & safety instructions

• Rack configuration
  • The system achieves its capacity by connecting up to 13 battery modules in series per rack. Ensure correct mechanical fixation in the control cabinet.
• Safety management
  • The integrated Smart BMS protects each module individually from overcharging, deep discharge and short circuit. Communication is seamless via CAN 2.0.
• Statics & weight
  • A fully equipped 100 kWh rack weighs about 900–1000 kg. Make sure the foundation at the installation location is designed for these loads.

FAQs about the Deye BOS-A 100 kWh storage

Can the 100 kWh system be further expanded?

Yes. Several racks can be connected in parallel to achieve total capacities in the megawatt range. The modular design makes it possible to adapt the system precisely to your company's growing energy needs.

How does the emergency power supply work at this size?

Automatic and powerful. Together with an appropriate Deye high-voltage inverter, the system can switch to battery operation within milliseconds in the event of a grid failure, continuing to supply even heavy industrial loads without interruption.

Why is the BMS so important in this system?

For balance and safety. With series connection of 13 modules, the BMS ensures all cells are charged and discharged evenly. This prevents premature ageing of individual modules and maximises the usable energy of the complete 100 kWh block.

Is the system high-maintenance?

No. Thanks to the fanless design of the battery modules and the robust LiFePO4 technology, the system is practically maintenance-free. Cloud-based remote monitoring also makes it possible to detect irregularities before they become a problem.
