Deye GE-F120-2H2

A 122.8 kWh high-voltage LiFePO4 battery system delivering 50 kW of rated DC power for commercial backup and solar storage, expandable to 10 parallel units.

Models Covered: DEYE-GE-F120-2H2

Manufacturer: Ningbo Deye Inverter Technology Co., Ltd

Application: The Deye GE-F120-2H2 puts 122.8 kWh of LiFePO4 storage behind a commercial building, workshop or large villa - enough to carry substantial loads through outages and peak-tariff hours. Its 50 kW of rated DC power moves energy quickly, while the 500-700 V operating window pairs it with high-voltage battery inverters rather than 48 V hybrids. The system assembles from 5.12 kWh modules of 44 kg each - a manageable two-person lift - and stands on the floor inside an IP55-rated enclosure that keeps dust and water jets out. When demand grows, up to 10 units run in parallel, with a stated maximum capacity of 3,600 kWh. An LCD shows status at a glance, and CAN, RS485, Wi-Fi and ETH ports connect it to monitoring. Deye states a 10-year warranty and a cycle life above 6,000 cycles to 70% of original capacity.

Figures on this page are the manufacturer's own, measured at the test conditions the datasheet states — they do not change by country. What changes is the approval that has to be met before the unit is energised: in Yemen that is Public Electricity Corporation (PEC), Ministry of Electricity and Energy. Confirm the grid code, import requirements and any local certification with them, or with us, before you order.

Key Features & Technical Highlights

  • 122.8 kWh modular capacity: Assembled from 5.12 kWh LiFePO4 modules at 51.2 V each, the system reaches 122.8 kWh of storage.
  • 50 kW rated DC power: Sustains 50 kW with a peak discharge current of 125 A for demanding commercial loads.
  • High-voltage 500-700 V design: Pairs with high-voltage battery inverters across a 500-700 V DC operating window.
  • IP55 floor-standing enclosure: Keeps dust and water jets away from the electronics in a floor-mounted cabinet.
  • Over 6,000 charge cycles: Rated beyond 6,000 cycles to a 70% end-of-life threshold, under a stated 10-year warranty.
  • Four communication channels: CAN, RS485, Wi-Fi and ETH ports connect the LCD-equipped system to monitoring.

Frequently Asked Questions

Which inverter class does the GE-F120-2H2 connect to?

It operates between 500 and 700 V DC, so it pairs with high-voltage battery inverters and power-conversion equipment - not with 48 V low-voltage hybrid inverters.

How large can a GE-F120-2H2 installation grow?

Up to 10 units can be connected in parallel, and the platform lists a maximum capacity of 3,600 kWh, so a site can start with one system and scale in stages.

What warranty and lifespan does the GE-F120-2H2 carry?

Deye states a 10-year warranty, a cycle life above 6,000 cycles and an end-of-life threshold of 70% of original capacity.

What temperatures can the GE-F120-2H2 work in?

It charges between 0 and 55 degrees C and discharges from -20 to 55 degrees C, with derating above 43 degrees; storage should stay between 0 and 35 degrees C at 15-85% non-condensing humidity.

How is the GE-F120-2H2 installed?

It is a floor-mounted system in an IP55 enclosure; each 5.12 kWh module weighs 44 kg and a complete system weighs 2,090 kg, so floor loading must be checked first.
