The BOS-G 5.1 is a high-voltage lithium-ion battery system that provides reliable backup power for supermarkets, banks, schools, farms and small factories. It can also be used to smooth the load curve and transfer peak loads. In particular, the device can increase the stability of renewable systems and promote the use of renewable energy.

It is characterised by integration with various devices, high reliability, long service life, a wide operating temperature range and many more parameters. The battery energy storage system is modular. Each battery module has a capacity of 5.12 kWh. In total, the system can support up to 12 battery modules connected in series. With the maximum number of modules installed, the total energy can be increased from 15.36 to 61.44 kWh.

The BOS-GM 5.1 is characterised by a quick and easy installation process. The built-in 19-inch screen provides hassle-free setup, making it user-friendly at all stages of operation. And the pleasant and simple interface makes it easy for both consumers and installers to work comfortably and easily.

Safety and reliability are of paramount importance in any energy storage system, and the BOS-GM 5.1 is no exception. The cathode material consists of LiFePO4, which is well known for its quality and long service life. In addition, the device demonstrates a low self-discharge rate, which allows it to be stored for up to six months without recharging. Excellent shallow charge and discharge characteristics further extend the battery’s lifespan, ensuring a stable and reliable power supply over a long period of time.

Equipped with an intelligent battery management system, this system is reliably protected by a large number of safety mechanisms. The BMS protects the device from various potential hazards, including overcharge and discharge, overcurrent and extreme temperature extremes. The comprehensive protection system not only ensures the safety of the battery, but also contributes to the lifetime of the entire energy storage system.

In addition, the BMS efficiently manages the charge and discharge states, effectively balancing the current and voltage of each cell for optimum performance. Operating in a wide temperature range from -20°C to 55°C, the BOS-GM 5.1 is ideal for almost all regions of the world.

Multiple battery modules can be easily connected in parallel, allowing users to scale capacity and power to suit their own wants and needs. The battery supports convenient updates via USB and, optionally, Wi-Fi, which facilitates remote management and compatibility with Deye inverters.

In conclusion, the BOS-GM 5.1 battery system from Deye is an efficient and cost-effective solution for energy storage. Convenient installation, safety mechanisms, extensive BMS functionality, environmental friendliness, flexible configuration and a wide temperature range make it an excellent choice for a variety of applications, from residential to commercial and industrial facilities.

Proper use of the appliance:

The battery energy storage system may only be installed and operated indoors. The operating temperature range of the BOS-G is -20°C ≈ 55°C and the maximum humidity is 85%. The battery module must not be exposed to sunlight or placed directly next to a heat source.

The battery module must not be exposed to a corrosive environment.

When installing the battery energy storage system, make sure that it is placed on a sufficiently dry and level surface with sufficient support. The installation site must not exceed an altitude of 2,000 metres without the written consent of the manufacturer. The output power of the battery decreases with altitude.

In areas subject to flooding, ensure that the battery module is installed at a suitable altitude. Do not allow it to come into contact with water.

The battery energy storage system must be installed in a fireproof room. This room must be free of any source of fire and must be equipped with an independent fire alarm device that complies with the local applicable codes and standards. According to local applicable regulations, the room must be separated by a T60 fire door. Similar fire protection requirements apply to other openings in the room (e.g. windows).

Compliance with the specifications in this manual is also part of the proper use of the appliance.

The use of the BOS-G system is prohibited in the following cases:

  • Mobile use on land or in the air (use on water only with the consent of the manufacturer and with the written permission of the manufacturer).
  • Use in medical devices.
  • Use as an uninterruptible power supply.
