Accessories for battery storage systems

The Deye BOS-G-PACK5.1 (BOS-G Pro) is a high-voltage, rack-mounted lithium battery module designed for residential and small-scale commercial and industrial (C&I) energy storage applications. Engineered with a standard 19-inch embedded format, the system is available across global markets (AU, AS, AF, EU & LATAM) and utilizes exceptionally safe Lithium Iron Phosphate (LiFePO₄) cell chemistry.

Key Features:

Scalable Energy: 

Each battery module provides 5.12 kWh of capacity. The system offers high flexibility, allowing for the connection of 5 to 16 modules in series to reach total system energy capacities ranging from 25.6 kWh to 81.92 kWh.

Long Lifespan:

Built for long-term reliability, the system features a cycle life of ≥6,000 cycles (at 25°C) and is backed by a 10-year warranty. The modules also exhibit a low self-discharge rate, capable of sitting on a shelf for up to 6 months without charging.

High Performance:

The system operates with a recommended 90% depth of discharge, an IP20 enclosure rating, and supports high-voltage charging. It features intelligent BMS management with CAN2.0 and RS485 communication for seamless integration and remote maintenance.

Flexible Installation:

The standard 19-inch rack-mounted design simplifies installation and maintenance, making it an ideal choice for space-constrained environments that require high-power energy storage for large appliances or industrial loads.
