The Deye BOS-W is a high-performance

scalable energy storage solution designed for small-scale commercial and industrial (C&I) applications. Built with advanced LiFePO₄ (LFP) battery technology, it offers safety, long cycle life, and intelligent energy management through an integrated Battery Management System (BMS).

Key Features:

1. Convenient & Modular Design:

   • 19-inch rack-mountable for easy installation and maintenance.

   • Supports parallel expansion for increased capacity and power.

2. Safety & Reliability:

   • LiFePO₄ chemistry ensures thermal stability and long lifespan (6,000 cycles at 70% capacity retention).

   • Comprehensive BMS protections: Overcharge/over-discharge, overcurrent, and temperature monitoring.

3. High Performance:

   • Wide operating temperature range: -20°C to 55°C.

   • Module capacity: 5.12 kWh (51.2V, 100Ah), scalable up to 87.04 kWh.

   • Peak discharge current: 120A (for 2 minutes).

4. Smart & Flexible:

   • Remote/USB firmware upgrades (compatible with Deye inverters).

   • Communication via CAN2.0 & RS485 for seamless system integration.

5. Eco-Friendly:

   • Non-toxic, pollution-free materials with UN38.3 certification.
