Deye BOS-A - 61.44 kWh high-voltage battery storage system for commercial and industrial applications

The Deye BOS-A system with a total capacity of 61.44 kWh is a high-performance storage solution based on lithium iron phosphate cells (LiFePO4). It has been specially developed for use in commercial buildings, industrial plants and for storing 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 6000 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 grows with your requirements – up to 13 modules can be connected in series to realise powerful high-voltage storage systems.
• Safety through Smart BMS: An integrated battery management system reliably protects against overcharging, deep discharge as well as short circuits and ensures the longevity of the cells.
• Easy installation: With a module weight of approximately 70 kg and a thoughtful rack design, installation in professional environments is quick and straightforward.
• Robust industrial design: Designed for use in a variety of environmental conditions with a high IP protection rating and a wide operating temperature range.
• Long-term guarantee: Rely on a 10-year guarantee and a full replacement guarantee for up to 6000 usage cycles.

FAQs on the Deye BOS-A high-voltage storage

What does "cloud-based monitoring" mean with BOS-A?

Real-time control from anywhere. Through the Deye Cloud platform, you can conveniently monitor your energy consumption and the state 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 requirements of the inverter and makes it easy to add further modules to the rack as energy needs grow.

Is the system environmentally friendly?

Yes. Thanks to the use of LiFePO₄ chemistry, Deye does not use toxic heavy metals such as cobalt. In addition, the high efficiency of over 90% ensures that almost no energy is lost during the storage process.
