Deye 5.12kWh High-Voltage Lithium LFP Battery (BOS-G)

Product Overview

The Deye BOS-G is a cutting-edge, high-voltage battery module designed specifically for large-scale energy storage in commercial and industrial (C&I) applications. Available at Powernest Limited, this unit is the essential building block for high-voltage systems (like the Deye 30kW inverter). By connecting these modules in series, the system achieves the high DC voltages required for maximum efficiency and reduced energy loss. Built with cobalt-free LiFePO4 chemistry, the BOS-G offers the highest level of safety and a compact 19-inch rack-mount design that fits perfectly into professional server-style cabinets.

Key Features

• High-Voltage Efficiency: Specifically designed to be connected in series (minimum of 3 or 4 modules depending on the inverter) to reach operational voltages up to 800V, significantly improving conversion efficiency for high-power demands.

• Superior Cycle Life: Rated for over 6,000 cycles at 90% Depth of Discharge (DoD), providing over a decade of reliable daily use in heavy-duty environments.

• Modular & Scalable: Each 5.12kWh module is easily stackable. A single cluster can expand up to 61.44kWh, and multiple clusters can be paralleled to meet megawatt-scale storage requirements.

• Advanced Safety (LFP): Uses Lithium Iron Phosphate (LiFePO4) chemistry, which is renowned for its thermal stability and safety, even under high-load conditions.

• Intelligent Cluster Management: Requires a High-Voltage Control Box (BMU) which manages the entire string, protecting against over-voltage, temperature spikes, and ensuring precise cell balancing across all modules.

• Quick Installation: Standard 19-inch 3U embedded design allows for rapid deployment and easy maintenance within standard industrial racks.
