SKU: BOS-G Category:


The BOS-G(HV) from Deye is an advanced system that uses lithium iron phosphate (LiFePO4) solar power battery banks designed specifically for solar energy applications.

With its modular and scalable architecture, it offers a flexible capacity range from 20.48kWh to 61.44kWh. The system consists of rack-mounted battery modules, each with a capacity of 5.12kWh. Multiple modules can parallel connect in strings to achieve the desired storage capacity. The standardized 3U enclosure design enables convenient installation and maintenance.

Key features of the solar power battery banks include a long 10+ year lifespan, integrated battery management system for protection, operating temperatures ranging from -20°C to +55°C, and depth of discharge up to 90% for excellent energy harvest. The intrinsically safe LiFePO4 chemistry also makes the system reliable and eco-friendly.

Advanced monitoring and control capabilities like remote upgrade over WiFi, compatibility with Deye hybrid inverters, and thermal management optimize system performance and lifespan.

With certifications like CE, IEC and UL, the BOS-G(HV) is positioned as a high-quality solar energy storage solution. Its flexible architecture can reliably support small-scale commercial and industrial applications from 20kW to 100kW.
