Deye GE-F120-2H2 – The future of smart energy management

The GE-F120-2H2 ‘ Deye ’ represents a new generation of high-performance hybrid energy storage systems for residential, commercial and industrial applications. With a rated power of 50 kW and an impressive storage capacity of 120 kWh, this high-voltage system is the ideal solution for complex energy requirements, maximum operational reliability and complete energy independence.

Highlights at a glance

• Generous storage capacity: 120 kWh of energy for peak loads and long-term buffering
   
• Fast charging/discharging: Optimised for dynamic energy cycles
   
• Redundant power supply: Maximum reliability for critical applications
   
• Black-start function: Automatic restart possible without a network connection
   
• Safe battery technology: Long-lasting & thermally stable LiFePO4 cells
   

Smart storage solution offering maximum flexibility

With the GE-F120-2H2, Deye combines state-of-the-art technology in a single integrated system: a hybrid inverter, lithium iron phosphate (LFP) batteries and an advanced energy management system (EMS) work seamlessly together. This enables energy flows to be optimised, self-consumption to be maximised and peak loads to be efficiently absorbed, entirely without external support.

Redundancy & Black Start: Reliable even in extreme circumstances

The redundant power supply design guarantees uninterrupted operation even in the event of partial failures. The black-start function allows the system to restart completely without an external power source, making it ideal for off-grid installations or in the event of power cuts in critical infrastructure.

LFP technology: Safety & service life

The LiFePO4 batteries fitted offer:

• High thermal stability
   
• Long service life & over 6,000 charge cycles
   
• Low risk of thermal runaway
   
• Sustainability & environmental friendliness
   

Who is the GE-F120-2H2 suitable for?

• Industrial plants with peak load management
   
• PV-powered emergency power supply in commercial buildings
   
• Off-grid power supply
   
• Critical systems requiring redundancy
   
• Large private estates with high energy

FAQs on the GE-F120-2H2 Energy Storage System ( Deye )

How much energy is actually available?

One cabinet provides a gross capacity of 120 kWh, of which around 110 kWh is usable at a 90% depth of discharge – ideal for commercial and industrial businesses with high storage requirements.

Is 50 kW sufficient for continuous loads?

Yes. The integrated power electronics (PCS) provide 50 kW of continuous power and can supply up to 125 A for 10 seconds, making it sufficiently rated even for peak loads.

Can I expand the system later?

Up to ten cabinets can be operated in parallel. This enables capacities of up to 1.2 MWh and a total AC output of 500 kW without the need for a system change or additional infrastructure.

How hot can the system get?

The cell temperature must not exceed 35 °C under full load. The integrated thermal management module automatically monitors and regulates the temperature to prevent a drop in performance or premature ageing.

Which inverter is suitable for the system?

The integrated 50 kW PCS is pre-configured at the factory for all three-phase Deye hybrid inverters in the SUN-29.9 kW to 50 kW series; plug-and-play operation is possible without additional components. It is strongly recommended that you check the compatibility list, as the manufacturer may make changes.

Do I need external NA protection?

No, the power conversion stack meets the requirements of VDE-AR-N 4105 and EN 50549-1/-2 and incorporates an integrated anti-islanding protection circuit; additional NA protection is not required.
