Deye BOS-G 61.44kWh Battery Specifications

61.44kWh Commercial Solar Battery Storage

With 61.44kWh of total battery capacity, this Deye battery bank is designed for applications requiring substantially more stored energy than conventional residential 5kWh, 10kWh or 15kWh lithium battery systems.

The large storage capacity makes the system particularly suitable for businesses, commercial properties, farms, workshops and industrial solar installations where maintaining energy availability and maximising solar self-consumption are important.

When connected to a correctly designed compatible high-voltage hybrid inverter system, excess solar energy can be stored in the BOS-G battery bank for later use.

12 × Deye BOS-G 5.12kWh Lithium Batteries

The system consists of 12 individual 5.12kWh BOS-G battery modules, providing a combined nominal storage capacity of:

12 × 5.12kWh = 61.44kWh

The modular battery architecture makes the BOS-G platform particularly suitable for larger energy-storage installations.

Rather than relying on one extremely large battery module, the rack-based design combines multiple battery modules into a professionally managed high-voltage battery bank.

LiFePO4 Battery Technology

The Deye BOS-G uses Lithium Iron Phosphate (LiFePO4) battery chemistry.

LiFePO4 has become a popular choice for modern commercial solar battery storage due to its safety characteristics, stability and suitability for repeated charging and discharging.

The chemistry is also cobalt-free, providing an energy-storage solution designed around long-term solar and backup applications.

Intelligent Battery Management System

The BOS-G system incorporates intelligent Battery Management System (BMS) functionality to manage and protect the high-voltage battery bank.

The system provides protection and management functions relating to:

• Overcharging
• Over-discharging
• Temperature conditions
• Cell and module voltage management
• Battery system operation

Temperature detection of critical components further assists with maintaining reliable battery operation.

Deye HVB750V/100A-EU Control Box Included

This complete battery package includes the Deye HVB750V/100A-EU Cluster Control Box.

The control box forms an essential part of the high-voltage battery system, providing central management between the battery modules and compatible inverter system.

BMS communication is supported through CAN and RS485.

Rack Included

A dedicated battery rack is included to house the 12 BOS-G battery modules and high-voltage control box.

The rack-based design provides a clean and organised solution for commercial battery installations while keeping the battery modules and control equipment together as a complete energy-storage bank.

Smart Monitoring & Remote Management

The Deye BOS-G platform provides monitoring and management functionality including:

• USB connectivity
• Wi-Fi functionality
• Remote system monitoring
• Remote firmware updates

These capabilities can assist installers and system operators with monitoring and maintaining larger commercial battery-storage installations.

Designed for High-Voltage Solar Systems

Unlike standard 48V or 51.2V lithium batteries, the BOS-G is designed specifically for high-voltage energy-storage applications.

This makes it suitable for pairing with compatible high-voltage commercial hybrid inverters and larger three-phase solar installations.

Battery configuration, system voltage, inverter model, firmware and BMS communication compatibility must be confirmed before installation.

Ideal Applications

• Commercial solar systems
• Industrial solar installations
• High-voltage hybrid inverter systems
• Commercial battery backup
• Businesses and office buildings
• Warehouses
• Factories and workshops
• Farms and agricultural installations
• Large-scale solar energy storage
• High-capacity backup systems
• Off-grid energy-storage applications
• Three-phase commercial solar systems

Installation & Warranty Requirements

The Deye BOS-G is a high-voltage battery system and must be installed and commissioned by appropriately qualified personnel.

Installation must comply with applicable South African electrical requirements, including relevant SANS 10142 requirements.

A valid Certificate of Compliance (COC) and the required installation documentation should be retained for warranty purposes.

The system carries a 10-year manufacturer warranty, subject to Deye's applicable warranty terms, installation requirements and operating conditions.

Why Choose the Deye BOS-G 61.44kWh Battery Set?

For customers building a large commercial solar and battery storage system, the Deye BOS-G 61.44kWh package provides a convenient complete battery-bank solution rather than purchasing individual modules and control components separately.

With 12 × 5.12kWh batteries, 61.44kWh total capacity, a dedicated HV control box, battery rack, intelligent BMS and CAN/RS485 communication, the system provides a strong foundation for a professional high-voltage solar energy-storage installation.
