Name: Deye BOS-W
Brand: Deye

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:

Convenient & Modular Design:
- 19-inch rack-mountable for easy installation and maintenance.
- Supports parallel expansion for increased capacity and power.
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.
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).
Smart & Flexible:
- Remote/USB firmware upgrades (compatible with Deye inverters).
- Communication via CAN2.0 & RS485 for seamless system integration.
Eco-Friendly:
- Non-toxic, pollution-free materials with UN38.3 certification.
