Deye BOS-G Pro 5.12 kWh High-Voltage Battery
 
The Deye BOS-G Pro 5.12 kWh High-Voltage Battery is a premium, modular energy storage solution designed specifically for high-voltage hybrid solar systems. Built using safe and durable Lithium Iron Phosphate (LiFePO₄) technology, the BOS-G Pro delivers long cycle life, advanced protection, and flexible scalability for commercial, industrial, and large residential applications.
Each 5.12 kWh module is designed to be connected in series to form a high-voltage battery stack, making it ideal for pairing with Deye’s high-voltage (HV) hybrid inverters available in South Africa.
 
Key Features:
Safe & Reliable LiFePO₄ Technology
Manufactured using Lithium Iron Phosphate (LiFePO₄) cells for superior safety, thermal stability, and long service life. The battery has low self-discharge, no memory effect, and excellent performance during shallow charge and discharge cycles.
 
Advanced Battery Management System (BMS)
Integrated intelligent BMS provides full protection against over-charge, over-discharge, over-current, short-circuit, and high or low temperature conditions. The system automatically balances voltage and current across each cell for optimal performance and longevity.
 
High-Voltage Modular Design
Each module has a nominal voltage of 51.2 V and is designed to be connected in series to form a high-voltage battery bank suitable for HV hybrid inverters.
 
Flexible & Scalable Energy Storage
System capacity can be expanded easily by adding more modules, allowing the battery bank to grow as energy requirements increase.
 
Convenient Installation
Standard 19-inch rack-mount (3U) design enables fast installation and easy maintenance in battery cabinets or racks.
 
Wide Operating Temperature Range
Designed to operate reliably in demanding environments, with a working temperature range from -20 °C to 55 °C, ensuring consistent performance in various climate conditions.
 
Environmentally Friendly
The BOS-G Pro battery is non-toxic, non-polluting, and environmentally friendly, supporting clean and sustainable energy solutions.
