Deye 5.12kWh 48V Lithium LFP Battery (SE-G5.1 Pro-B)

Product Overview

The Deye SE-G5.1 Pro-B is a high-performance Lithium Iron Phosphate (LiFePO4) battery designed for safety, longevity, and seamless integration with Deye hybrid inverters. Available at Powernest Limited, this 48V (51.2V nominal) unit is the industry standard for residential and commercial energy storage. Unlike traditional batteries, the Deye LFP series uses cobalt-free chemistry, ensuring thermal stability and an eco-friendly footprint while delivering the high discharge current needed to support heavy start-up loads.

Key Features

• Long Cycle Life: Engineered for endurance, providing over 6,000 cycles at 90% Depth of Discharge (DoD). This ensures more than 10–15 years of daily reliable service under standard conditions.

• Safe LFP Chemistry: Utilizes Lithium Iron Phosphate (LiFePO4), the most stable lithium technology available, eliminating the risk of thermal runaway and ensuring safety for indoor installations.

• Massive Scalability: The modular design allows you to parallel up to 64 units, creating a total storage capacity of up to 327kWh for large-scale industrial or off-grid projects.

• High Discharge Power: Supports a continuous discharge current of 100A and a peak current of 150A (for 2 minutes), allowing a single battery to handle significant power spikes from household appliances.

• Intelligent BMS: The built-in Battery Management System (BMS) automatically monitors cell voltage, current, and temperature, while also balancing cells during charging to maximize lifespan.

• Remote Monitoring & Updates: Fully compatible with the Deye solar portal, allowing for remote firmware upgrades and real-time health monitoring via Wi-Fi or LAN.
