The Deye BOS-GH40 High Voltage Battery is a robust and scalable energy storage solution designed for commercial and industrial applications. Built with advanced LiFePO₄ chemistry, it delivers outstanding safety, thermal stability, and long-term reliability, making it ideal for demanding energy environments.
With a recommended 90% depth of discharge and over 6,000 cycles at 70% end-of-life, this system ensures maximum usable energy and excellent return on investment over its 10-year warranty period.
Engineered for flexibility, the rack-mounted design allows easy integration into existing systems, while CAN2.0 and RS485 communication ensure seamless compatibility with modern inverters and energy management platforms. Operating reliably from -20°C to 55°C (discharge), it performs consistently even in harsh environments.
Despite its high capacity (~40 kWh system), the unit maintains a compact footprint and manageable installation format. Certified to UL1973, UL9540, and UN38.3 standards, the BOS-GH40 guarantees compliance with global safety and transport requirements.
An ideal choice for businesses seeking efficient, safe, and future-ready high-voltage energy storage.
