Core Advantages for Project Stakeholders

Unmatched Energy Density & Scalability: The modular design allows for parallel expansion, easily scaling from 2.5MW to tens of megawatts to meet growing business needs. This flexibility ensures your initial investment is future-proofed against increasing energy demands.

Advanced Liquid Cooling System: Our smart liquid cooling technology maintains optimal cell temperatures, enhancing performance consistency and extending battery life. This ensures stable operation even under high-rate continuous charge/discharge cycles, which is critical for applications like EV fast-charging.

Superior Economics (LCOE): The combination of high cycle life, low degradation, and reduced maintenance requirements delivers the lowest levelized cost of storage in its class. With peak shaving capabilities, the system can reduce peak demand charges by up to 40%, providing a clear and rapid payback period for industrial and commercial end-users.

Global Supply Chain Assurance: Leveraging our mature supply chain and manufacturing scale, we guarantee industry-leading lead times. Our global logistics network ensures secure sea shipping and on-time delivery to any major port worldwide, with comprehensive project documentation and customs support included.

Product Overview & Safety Architecture

The Container ESS is engineered with a multi-layered safety architecture that goes beyond standard certifications. The system integrates an advanced multi-level fire suppression system (aerosol or gas-based) and an intelligent BMS that monitors cell voltage, temperature, and current with milli-second precision. The IP65-rated enclosure protects against dust and water ingress, making it suitable for outdoor installations in diverse climates.

Active Cell Equalization and Thermal Management: The BMS employs active cell balancing to maximize usable capacity and prevent over-charge/over-discharge, extending the overall system lifespan. The bi-directional PCS supports seamless grid-tied and off-grid transitions, ensuring a stable power supply and supporting micro-grid applications.

Grid Code Compliance & Interconnection: The system is pre-configured to meet various global grid codes, including UL 9540, UL 9540A (thermal runaway protection), IEC 62477, and CE certifications. It supports standard communication protocols (Modbus, CANbus, IEC 61850) for easy integration with existing site management systems.

Application Scenarios

EV Supercharging Stations & High-Load Datacenters

This Container ESS is the optimal solution for EV supercharging stations, providing high-power buffering to stabilize the grid and reduce costly demand spikes. The high C-rate capability of the Tier-1 LFP cells supports rapid charging events while protecting the site’s electrical infrastructure.

For industrial parks and manufacturing facilities, the system acts as a reliable backup power source and enables significant peak shaving savings. It can also integrate seamlessly with on-site solar PV (PV-Storage-Charging) to maximize renewable energy self-consumption and achieve zero-carbon operational goals.

The system’s micro-grid ready capabilities make it ideal for remote mining operations or island communities, reducing reliance on expensive and polluting diesel generators and creating a resilient, independent power supply.

We understand that project success depends on reliable execution. Our supply assurance program is built on a global network of certified component partners and high-volume manufacturing capacity. We offer a 10-Year Performance Warranty that guarantees capacity retention, protecting your investment over the long term.

Beyond delivery, our commitment is reinforced by a global network of local O&M partners. This ensures rapid response times, scheduled preventive maintenance, and on-site technical support, minimizing system downtime and maximizing energy yield for the project’s lifecycle. With our support, you can be confident in a smooth project handover and long-term operational success.

Frequently Asked Questions (B2B Procurement)

What is the typical lead time for a 2.5MW/5MWh Container ESS?

Our standard production lead time is 8-10 weeks from order confirmation and deposit receipt. This includes all assembly and rigorous Factory Acceptance Testing (FAT). We also offer expedited shipping options for urgent projects.

What certifications does this Container ESS hold?

The system is fully certified with UL 9540 (United States), IEC 62619 (international), CE (Europe), and UN 38.3 (transportation). Individual component certifications, such as UL 1973 for cells, are also available upon request.

Can this system be expanded in the future?

Yes, this model is designed for modular scalability. Multiple units can be connected in parallel via a common AC busbar to increase capacity from MW to multi-MW scales, making it suitable for future expansion without significant re-engineering.

What are the shipping dimensions and weight of the unit?

The standard 20-foot containerized unit measures 20ft x 8ft x 8.5ft. The total weight is approximately 40,000 kg (varies with configuration). Detailed shipping documentation, including packing lists and labeling, is provided with each unit to ensure hassle-free international transport.

How does the 10-Year Performance Warranty work?

Our warranty guarantees that the usable capacity will not degrade below 80% of its initial rated capacity after 10 years of standard operation.
