for Medium-to-Large C&I Projects
This commercial energy storage system is engineered for medium to large commercial and industrial projects where higher energy capacity, long daily cycling, and system scalability are critical. With a single-cabinet capacity of 261.25 kWh, it serves as a standardized building block for industrial parks, factories, logistics centers, and distributed microgrid applications that require stable, repeatable energy storage deployment.
Rather than targeting small standalone installations, this system is designed to support project-level energy storage, where multiple cabinets operate in parallel to deliver predictable performance, long service life, and optimized lifecycle economics.
Designed for Project-Scale Commercial Deployment
For EPC contractors and energy project developers, installation space, system consistency, and expandability are key considerations. This battery energy storage cabinet delivers a high energy density within a compact footprint of approximately 1.4 m², allowing higher capacity deployment without increasing site complexity.
The cabinet integrates battery modules, thermal management, protection systems, and communication interfaces into a single outdoor-rated unit, reducing on-site integration work and improving construction efficiency across multi-cabinet projects.

Typical Applications
This 261 kWh commercial energy storage system is well suited for:
- Commercial and industrial peak shaving and load shifting
- Solar PV + battery energy storage systems
- Backup power for factories, data centers, and commercial buildings
- Microgrid energy storage projects
- Distributed energy storage for business parks and industrial zones
Built for Commercial-Grade Operation
For most commercial and industrial buyers, cycle life is one of the first parameters they evaluate, because it directly determines the real return on investment of an energy storage project. This system is designed to deliver ≥8000 charge–discharge cycles at a 95% depth of discharge, which places it firmly in the category of long-life commercial energy storage equipment.
In practical terms, this means the battery can sustain daily cycling for well over ten years under typical peak shaving, load shifting, or solar self-consumption scenarios. For EPC contractors and commercial operators, a cycle life of ≥8000 cycles translates into lower levelized cost of storage (LCOS), fewer replacements, and more stable long-term project economics. It is a critical factor for sites where the energy storage system is expected to operate every day, not just as an occasional backup, making this parameter one of the strongest value points of the system in real-world commercial applications.
FAQ
Q: This system is labeled as a commercial energy storage system. What applications is it best suited for?
A: This system is designed specifically for commercial and industrial (C&I) applications, including peak shaving, load shifting, solar PV + storage integration, backup power, and microgrid projects. Its 261.25 kWh single-cabinet capacity and scalable architecture make it suitable for factories, commercial buildings, industrial parks, and distributed energy storage projects.
Q: What is the expected lifespan of the system under normal operation?
A: The system supports ≥8000 charge–discharge cycles at up to 95% depth of discharge. Under typical commercial operating conditions, such as daily cycling for peak shaving or solar self-consumption, this translates into more than 10 years of stable operation.
Q: How quickly can the system switch between charge and discharge modes?
A: The charge and discharge switching time is less than 100 milliseconds, ensuring fast response for grid support, load management, and backup power applications.
Q: What are the rated and maximum power outputs of the system?
A: The system has a rated AC power output of 125 kW and can deliver up to 137 kW continuously for one minute, allowing it to handle short-term peak loads in commercial applications.
Q: What certifications and standards does the system comply with?
A: The system complies with major international and regional standards, including GB/T 36276, GB/T 34120, GB/T 34131, UN38.3, IEC 62477, IEC 61000, IEC 62619, IEC 63056, UL 9540A, and EN 50549, supporting global project deployment.
