Flexible Solution

As businesses accelerate their transition toward cleaner, more resilient, and energy-efficient operations, Battery Energy Storage Systems (BESS) are becoming an increasingly important part of modern energy infrastructure. Designed to meet the evolving needs of Commercial and Industrial (C&I) applications, the Deye GE-F128 is a 128.61 kWh integrated Battery Energy Storage System (BESS) that combines advanced Lithium Ferro Phosphate (LiFePO₄) battery technology, intelligent energy management, and comprehensive safety features within a compact, factory-integrated cabinet.

The GE-F128 is compatible with 30 kW to 60 kW Deye hybrid inverters, providing flexibility to configure the system according to different project requirements. Its versatile design makes it suitable for a wide range of C&I applications, including islands, farms, malls, and factories, where reliable and flexible energy management is essential.

Multi-Layered Safety for Reliable Operation

Safety is a key feature of the GE-F128. The system incorporates Deye's Six-Dimensional Safety Design, which combines electrical isolation, fire detection, active exhaust, explosion venting, fire suppression, and thermal isolation to provide multiple layers of protection throughout system operation.

The safety architecture is further supported by a high-strength cabinet structure, patented door-latch design, and hour-level fire resistance. Together, these features are designed to enhance system safety and provide dependable operation in demanding C&I environments.

Intelligent and Scalable System Architecture

At the core of the GE-F128 is Deye's self-developed 3S Intelligent Control Platform, which integrates the Battery Management System (BMS), Power Conversion System (PCS), and Energy Management System (EMS) for coordinated system control and real-time monitoring.

The GE-F128 supports both grid-connected and off-grid operation, providing flexibility for different energy-management requirements. The system can also be expanded as project requirements grow. Up to 10 battery cabinets can be connected in parallel on the DC side for increased energy capacity, while up to 10 inverter units can operate in parallel on the AC side to expand system power capacity.

High-Performance LiFePO₄ Battery Technology

The GE-F128 uses high-performance LiFePO₄ battery technology designed for long-term and stable operation. The system supports more than 8,000 charge-discharge cycles and can accommodate up to 160 percent PV capacity, enabling greater integration of solar generation.

The system also maintains no power derating at ambient temperatures up to 45°C, supporting reliable operation in demanding environmental conditions. Its optimised thermal-management design maintains a cell temperature difference of ≤6°C, helping improve battery consistency, longevity, and overall system performance.

Smarter Energy Management with Deye Cloud

The GE-F128 is further supported by Deye Cloud, an integrated energy and device management platform that provides real-time monitoring and intelligent energy-management capabilities.

Through Deye Cloud, users can monitor equipment performance, implement intelligent charging and discharge strategies, and utilise dynamic tariff functions to optimise energy consumption. The platform also incorporates Deye Copilot for AI-powered energy analysis and a 24/7 AI Assistant to support system operation and management.

Available through both web and mobile applications, Deye Cloud provides multilingual support and flexible system-control functions, helping users monitor their energy assets and improve operational efficiency.

A Flexible Solution for Modern C&I Energy Needs

By combining a 128.61 kWh battery platform, flexible inverter compatibility, intelligent 3S control, multi-layered safety architecture, scalable system expansion, and cloud-based energy management, the Deye GE-F128 provides a comprehensive energy storage solution for modern C&I applications.

Its compact integrated design simplifies system deployment while its scalable architecture enables the system to adapt to changing power and energy requirements. With advanced LiFePO₄ technology, intelligent monitoring, and flexible operating modes, the GE-F128 is designed to support businesses in building more efficient, resilient, and sustainable energy infrastructure.
