As global energy systems continue transitioning toward low-carbon and flexible infrastructure, hybrid power solutions are becoming increasingly important. In many real-world applications—such as remote industrial sites, commercial facilities, and off-grid projects—neither solar nor diesel alone can fully meet demand for stability and efficiency. This is where containerized solar-diesel storage systems play a critical role, combining renewable energy, conventional generation, and energy storage into a unified platform.
Among the companies advancing this field, Fong Power Technology Co., Ltd., a high-tech enterprise recognized as a Beijing “Specialized, Advanced, and Innovative” company, has developed a series of integrated hybrid energy storage solutions designed to improve energy efficiency, system reliability, and operational intelligence.
Why Hybrid Container Energy Systems Are Becoming Essential
Traditional power supply models often struggle in environments where energy demand fluctuates or grid access is unstable. Hybrid container systems solve this challenge by combining multiple energy sources into a single managed platform.
The main advantages include:
-
Modular deployment: Container-based design allows fast installation and relocation, making it suitable for remote areas or rapidly expanding projects.
-
Stable power output: By combining solar PV, diesel generators, and grid input, the system ensures continuous energy supply even under unstable conditions.
-
Improved operational efficiency: Intelligent control of energy flow reduces waste and improves overall system utilization.
-
Lower emissions: Reduced reliance on diesel fuel contributes to lower carbon output and better environmental performance.
These systems are widely used in industrial parks, distributed energy projects, commercial buildings, and EV charging infrastructure.
Fong Power Technology’s Containerized ESS Approach
Fong Power Technology focuses on standardized yet highly flexible energy storage systems, offering both air-cooled and liquid-cooled container solutions in capacities such as 120kWh, 200kWh, and 400kWh. One of its key solutions is the FZKJ-Cube-1205 PV-Storage-Diesel-Grid-Hybrid ESS, a 1205kWh liquid-cooled container system designed for high-demand applications.
Key technical highlights include:
-
Scalable energy capacity: Configurations ranging from 1MWh up to 5MWh, allowing adaptation to different project scales
-
Advanced liquid cooling system: Maintains stable battery temperature even under high-load or extreme environmental conditions
-
Long-life LFP battery technology: Provides strong safety performance and extended lifecycle stability
-
Noise control design: Liquid cooling architecture keeps operational noise below 70 dB, suitable for urban and commercial installations
-
Multi-source energy compatibility: Supports seamless switching and coordination between solar, diesel, and grid power sources
This combination allows the system to operate efficiently across diverse energy environments while maintaining reliability and flexibility.
Intelligent Energy Management System (EMS)
A key component of Fong Power Technology’s solution is its independently developed FongPower EMS, which coordinates multiple energy inputs and ensures optimized system performance.
Rather than operating each energy source independently, the EMS integrates them into a unified control framework.
Core capabilities include:
-
High-performance computing platform: Built on a quad-core ARM Cortex-A55 processor with 1TOPS computing capability for real-time decision-making
-
Flexible communication architecture: Supports RS232, RS485, CAN, Ethernet, USB, HDMI, and analog/digital I/O for system integration
-
Advanced energy strategies: Includes peak shaving, load tracking, PV-storage coordination, anti-backflow control, demand response, and scheduled energy management
-
Remote operation and cloud connectivity: Enables monitoring, OTA updates, and integration with external energy platforms and grid systems
Through intelligent EMS control, the system improves energy efficiency, reduces diesel consumption, and extends battery lifespan while providing full visibility for operators.
Performance in Challenging Environments
Containerized energy storage systems are often deployed in demanding outdoor or industrial conditions. Fong Power Technology designs its systems to remain stable in environments such as:
-
