5MWh 2.5MW BESS

Lingtech Launches 5MWh 2.5MW AC-Coupled BESS with Grid-Following Technology for Scalable Energy Storage Applications

Lingtech is proud to announce the release of its latest 5MWh / 2.5MW Battery Energy Storage System (BESS), designed as an AC-coupled, grid-following solution to meet the growing global demand for reliable, flexible, and cost-efficient energy storage systems. This advanced system is engineered to seamlessly integrate with existing power infrastructure, including solar PV, diesel generators, and utility grids.

Optimized AC-Coupled Architecture for Maximum Flexibility

The Lingtech 5MWh BESS adopts an AC-coupled configuration, enabling easy integration with both new and existing energy assets. Compared to DC-coupled systems, AC coupling provides greater flexibility for retrofitting projects and hybrid energy systems, particularly in commercial, industrial, and utility-scale applications.

This architecture allows:

• Independent operation and control of PV systems and battery storage
• Simplified system expansion and upgrades
• Enhanced compatibility with multi-energy sources

Grid-Following PCS for Stable and Efficient Operation

The system utilizes a grid-following Power Conversion System (PCS), which operates by synchronizing with an existing voltage source such as the utility grid or a generator. This makes it an ideal solution for environments where a stable grid or primary power source is available.

Key characteristics of the grid-following design include:

• High efficiency in energy conversion and dispatch
• Stable synchronization with grid frequency and voltage
• Proven reliability for grid-connected and hybrid applications

While not designed for standalone grid-forming applications, this system excels in grid-supported scenarios, delivering consistent performance and optimized energy management.

High-Capacity 5MWh Energy Storage for Diverse Applications

With a total storage capacity of 5MWh and a rated power output of 2.5MW, this BESS is well-suited for a wide range of use cases:

• Renewable Energy Integration: Smooths solar and wind power fluctuations
• Peak Shaving & Load Shifting: Reduces electricity costs for commercial and industrial users
• Backup Power Support: Works alongside generators to enhance system reliability
• Grid Services: Supports frequency regulation and demand response

Advanced Lithium Battery Technology

The system is built on high-performance lithium iron phosphate (LFP) battery cells, ensuring:

• Long cycle life and high safety standards
• Excellent thermal stability
• Compliance with international certifications such as IEC, UL, and UN standards

Intelligent Energy Management System (EMS)

Lingtech’s integrated Energy Management System (EMS) enables real-time monitoring, intelligent dispatch, and remote operation. The EMS optimizes system performance by balancing energy supply and demand while ensuring safe and efficient operation.

Scalable and Future-Ready Design

The modular design of the Lingtech 5MWh BESS allows for easy scalability, making it adaptable to future energy needs. Whether deployed as a standalone system or as part of a larger energy network, it provides a future-proof solution for evolving power requirements.

Conclusion

The launch of the Lingtech 5MWh 2.5MW AC-Coupled Grid-Following BESS marks another milestone in Lingtech’s commitment to delivering innovative and reliable energy storage solutions. With its flexible architecture, proven grid-following technology, and high-capacity performance, this system is positioned to support the global transition toward cleaner and smarter energy systems.
