Deye GE-F120-2H2: All-in-One 50 kW / 120 kWh Energy Storage for Demanding C&I Applications

As commercial and industrial energy users face rising electricity costs, grid instability, and increasing demand for reliable backup power, integrated energy storage systems are becoming a critical part of modern infrastructure. The Deye GE-F120-2H2 is designed precisely for these challenges, offering a compact, all-in-one solution that combines power conversion, battery storage, and intelligent energy management in a single robust cabinet.

With a rated output power of 50 kW and a storage capacity of approximately 120 kWh, the GE-F120-2H2 is ideal for high-rate cyclic charging and discharging scenarios such as peak shaving, load shifting, backup power, and hybrid PV-storage systems. Its integrated architecture simplifies deployment while delivering the performance and safety required in professional environments.

Integrated Technology for Simplified System Design

The GE-F120-2H2 brings together PCS, hybrid inverter, BMS, and EMS within one enclosure, reducing system complexity and minimizing installation time. This unified design enables seamless coordination between power conversion and battery management, ensuring stable operation across a wide range of use cases.

Operating on a three-phase grid configuration (3L/N/PE), the system delivers AC output at 50/60 Hz with voltage options of 220/380 V or 230/400 V, supporting diverse regional grid standards. With a rated AC output current of 75.8 A, it easily meets the demands of commercial facilities and industrial processes.

Built for Safety, Stability, and Long-Term Performance

Safety is a central focus of the GE-F120-2H2. The system uses Lithium Iron Phosphate (LiFePO₄) battery technology, known for its thermal stability and long service life. To further enhance protection, Deye integrates an aerosol fire-extinguishing solution, along with continuous monitoring for combustible gas, smoke, and temperature anomalies. Active exhaust and fire alarm systems work together to mitigate risks before they escalate.

Advanced thermal management ensures that the maximum battery temperature remains below 35°C during rated power operation, even under demanding conditions. This controlled operating environment contributes to extended battery life, with the system rated for over 6,000 cycles at 70% end-of-life capacity, backed by a 10-year warranty.

Flexible Deployment and Scalable Backup Power

The GE-F120-2H2 is designed for flexibility. While each unit provides approximately 122.8 kWh of usable energy, the system supports parallel operation of up to 10 units in off-grid mode, enabling larger backup or islanded power solutions when required. Black-start capability and power-supply redundancy further enhance resilience in critical applications.

The floor-mounted cabinet, measuring 1780 × 1056 × 2235 mm and weighing around 2090 kg, is engineered for straightforward installation in plant rooms, energy centers, or sheltered outdoor locations. With an IP55 enclosure rating, it offers reliable protection against dust and moisture.

Reliable Operation in Diverse Environments

Designed for real-world conditions, the GE-F120-2H2 operates across a wide temperature range from –20°C to 55°C, with controlled derating above 43°C. Storage temperatures from 0°C to 35°C make logistics and long-term system management straightforward across various climates and regions.

With a round-trip efficiency of up to 89%, the system balances efficiency and durability, delivering predictable performance and long-term economic value for commercial and industrial users.

A Compact, Future-Ready C&I Energy Storage Solution

The Deye GE-F120-2H2 is a powerful example of how integrated energy storage can simplify system design while delivering high performance, safety, and flexibility. Whether deployed for peak shaving, backup power, or hybrid renewable energy systems, it provides businesses with greater control over energy costs and operational continuity.
