The system combines a power conversion system, inverter, battery management system and energy management system in an all-in-one architecture.

For the Australian model, the documented energy configuration is 122.8kWh, with 100kWh of usable energy. The DEYE GE-F120-2H6 provides 50kW nominal output / UPS power, an AC output rated current of 72.5A and a battery operating voltage of 500–700V. It uses LiFePO4 battery chemistry and is floor-mounted in an IP55 enclosure.

The battery system is designed with local management functions for monitoring voltage, current, temperature, humidity and smoke. Its battery management system also balances battery capacity. The system supports black start, off-grid operation and parallel expansion, making it suitable for the small-scale commercial & industrial applications identified by Deye, including farms, malls or shops and factories.

Key Features of Product

122.8kWh Energy Configuration

The DEYE GE-F120-2H6 has an energy configuration of 122.8kWh and 100kWh system usable energy. The system uses battery modules rated at 51.2V and 5.12kWh each, with CAN communication for the battery management system.

50kW Nominal Output

For the DEYE GE-F120-2H6, the nominal output / UPS power is 50kW, with an AC output rated current of 72.5A. The battery operating voltage is 500–700V. The system has a maximum RTE of 89%.

Integrated System Architecture

The DEYE GE-F120-2H6 battery system integrates PCS, inverter, battery BMS and EMS. The local management system monitors key operating parameters. This architecture brings the main energy storage and power conversion functions into a single cabinet.

LiFePO4 Battery Chemistry

The system uses LiFePO4 battery chemistry. The GE-F120-2H6 battery modules have a specified cycle life of at least 6,000 cycles under the stated test conditions of 25°C ±2°C, 0.5C charge/discharge and 70% EOL.

Multi-Layer Protection

The supplied brochure identifies combustible gas, smoke and temperature detection, active exhaust and fire alarm functions. The battery system also uses an aerosol fire suppression solution. An explosion relief plate and combustible-gas exhaust arrangement are described in the user manual.

Cooling & Environmental Protection

The cabinet has an integrated air-cooled air-conditioning system designed to maintain the BESS at a constant temperature. The enclosure is rated IP55. The specified storage temperature is 0–35°C, while the operating temperature is -20–55°C, with derating above 43°C.

Monitoring & Communication

The system supports CAN, RS485, RS232 and Wi-Fi communication according to the supplied product information. Deye also provides Deye Cloud for data acquisition, monitoring and operation and maintenance functions.

Parallel Expansion

The GE-F120-2H6 supports up to 10 units in parallel in off-grid operation according to the product documentation. The brochure also presents expansion configurations using multiple GE-F120 units for larger energy storage requirements.

Main Benefits

For Farms, Shops & Factories

Deye identifies this high voltage C&I battery system within its small-scale commercial and industrial applications, including farms, malls or shops and factories. The GE-F120-2H6 combines 50kW nominal output with 100kWh usable energy in one integrated system.

For Off-Grid Applications

The system supports black start and off-grid operation. Its documented parallel capability also allows multiple units to be configured when greater capacity or longer power support duration is required.

For System Monitoring

The local management system monitors voltage, current, temperature, humidity and smoke, while the BMS balances battery capacity. Communication interfaces and Deye Cloud provide options for system data acquisition and monitoring.

For Long-Term Operation

The battery specification states a cycle life of at least 6,000 cycles under the stated test conditions, while the system warranty is 10 years. The brochure also states 70% EOL under the specified cycle-life conditions.

Installation

Installation of the GE-F120-2H6 must be performed by professional electrical technicians and in accordance with the relevant local requirements. The following is a simplified overview of the manufacturer’s installation procedure.

1. Check the Equipment Before Installation

Check the cabinet and internal equipment against the packing list and inspect for damage. Confirm that the installation area is ready before moving the equipment.

2. Prepare the Installation Environment

The system can be installed indoors or outdoors. The installation area should be dry and well ventilated, away from toxic or harmful gases and flammable, explosive or corrosive materials.

For outdoor installation, the foundation must provide sufficient mechanical support and drainage. Deye recommends a foundation height of at least 300mm and requires the foundation to be level, secure, flat and able to support the equipment weight.

For indoor installation, the manual specifies an air volume of 2,000m³/h and requires a non-enclosed, ventilated environment. At least 500mm should be reserved above the cabinet for fire-hose connection. When installed against a wall, the rear of the cabinet should be at least 800mm from the wall because of the blast release plate.

3. Transport & Position the Cabinet

For forklift transport on a flat site, the manual specifies a forklift with a rated load of more than 3,000kg. Keep the cabinet upright during transport and avoid tilting or turning it upside down.

For crane lifting, the manual specifies a 25-ton crane and requires professional supervision, appropriate slings and compliance with crane safety procedures.

4. Secure the Cabinet

Position the cabinet on the prepared foundation and use the specified expansion-screw fixing method. Check that the cabinet is correctly positioned and securely fixed before electrical connection.

5. Complete the Electrical Connections

All electrical connections must be carried out with the equipment completely powered off by qualified electrical personnel. Internal battery modules are connected in series, with the specified power and communication cables used for battery-to-battery and battery-to-PDU connections.

The manual specifies cable requirements for the LOAD, GRID and GEN connections, as well as PE connections. PV wiring must also follow the specified DC isolation, polarity, voltage and cable requirements.

6. Inspect Before Power-On

After electrical connection, check all wiring carefully, confirm that air inlets and outlets are unobstructed, and seal cable entry points correctly. Before operation, verify the wiring, emergency stop status, absence of ground faults, AC and DC voltage conditions and that no tools or parts remain inside the equipment.

7. Power On the System

For the documented GE-F120 cabinet, the power-on sequence begins with the DC circuit breaker and START controls on the PDU, followed by the power distribution circuit breakers and inverter controls in the specified order. The exact sequence must be followed according to the manual.

Because this is a high-voltage energy storage system, installation, electrical connection, commissioning and maintenance should only be undertaken by appropriately qualified personnel.
