Deye BOS-A – 61.44 kWh high-voltage battery storage

The Deye BOS-A System with a total capacity of 61.44 kWh is a high-performance storage solution based on lithium iron phosphate (LiFePO4) cells. It has been specially developed for use in commercial buildings, industrial facilities and for the storage of renewable energy. The system is based on the modular BOS-A battery module, which is characterised by simple installation, high safety and intelligent monitoring.

By connecting up to 13 modules in series (per rack), the BOS-A system offers a flexible high-voltage configuration that minimises conversion losses and enables seamless integration into modern energy management systems.

Highlights at a glance

• High performance: A single module offers 7.68 kWh of capacity and is designed for over 6,000 charge cycles, guaranteeing an extremely long service life.
• Intelligent cloud management: Thanks to the Deye cloud platform, battery status and energy consumption can be monitored and optimised in real time to effectively reduce electricity costs.
• Flexible scalability: The system scales with your requirements – up to 13 modules can be connected in series to create high-performance high-voltage storage systems.
• Safety through Smart-BMS: An integrated battery management system provides reliable protection against overcharging, deep discharge and short circuits, ensuring the longevity of the cells.
• Easy installation: With a module weight of approx. 70 kg and a well-designed rack, installation in professional environments is quick and straightforward.
• Robust industrial design: Designed for use in various environmental conditions with a high IP rating and a wide operating temperature range.
• Long-term warranty: You can rely on a 10-year warranty and a full replacement guarantee for up to 6,000 usage cycles.

FAQs on the Deye BOS-A high-voltage storage system

What does "cloud-based monitoring" mean for the BOS-A?

Real-time monitoring from anywhere. Via the Deye cloud platform, you can conveniently monitor your energy consumption and the condition of the batteries via smartphone or PC. This enables proactive maintenance and helps to continuously optimise the system’s performance.

What is the maximum number of modules that can be combined?

Up to 13 modules in series. This flexible configuration allows the system voltage to be precisely matched to the inverter’s requirements and makes it easy to add further modules to the rack as energy demand grows.

Is the system environmentally friendly?

Yes. By using LiFePO4 chemistry, Deye avoids the use of toxic heavy metals such as cobalt. Furthermore, the high efficiency of over 90% ensures that hardly any energy is lost during the storage process.
