Features and benefits:
Modular and scalable design
The BOS-B Pro-A3 system consists of battery modules (each ~16.08 kWh) that can be connected in series of 5 to 16 units. This configuration allows for easy scaling of the total energy capacity to meet the needs of the facility, from small businesses to large industrial complexes.
High energy capacity
- Nominal system energy: ≈257.23 kWh
- Energy used at the recommended depth of discharge of 90%: ≈231.51 kWh
- This ensures continuous power supply to critical loads and significantly reduces energy costs.
Efficiency and Management
The system is equipped with a modern PCS (Power Conversion System) with an efficiency of ≈98.5% and MPPT >99%, which guarantees optimal use of energy from generation and minimizes conversion losses.
Fast switching and reliability
STS (Static Transfer Switch) technology ensures seamless switching of ≤20 ms between the grid, diesel generator and load, which is important for challenging plant operating conditions.
Intelligent Battery Management System (BMS)
The system is controlled by an advanced BMS, which is responsible for:
- optimal charging balance between modules,
- overcharge and deep discharge protection,
- real-time battery health monitoring.
The DEYE BOS-B Pro-A3 Battery for C&I Energy Storage is a high-performance and scalable energy storage system offering maximum flexibility for modern business energy systems. It combines large capacity, advanced management technologies, high efficiency, and reliability, making it a premium solution for commercial and industrial applications.
