The battery energy storage (BESS) market in Vietnam is entering a phase of potential development, opening up great opportunities for businesses to invest in clean energy technology. However, the success of a BESS project does not only depend on the quality of the battery or inverter, but is also determined by a fundamental component: the BESS container shell.
This is not a conventional container, but a complex technical system, designed to protect, optimize and ensure the safety of the entire system throughout its operating life. Therefore, choosing the right partner to produce the container shell is a strategic decision, directly affecting the efficiency and reliability of the entire project.
Below are 5 important criteria that every investor needs to carefully consider when choosing a BESS container manufacturer.
1. Deep Technical Competence and Practical Experience
BESS container manufacturing requires a deep understanding of many technical fields, not just mechanical processing. A competent partner must have a multidisciplinary team of engineers, capable of consulting and designing a comprehensive solution.
- Understanding the BESS system: Manufacturers must understand the structure and operating principles of a complete BESS system, from how the battery cells are arranged, the space requirements for the power conversion system (PCS), to the complex interactions between auxiliary systems such as thermal management (HVAC), battery management (BMS) and fire protection (PCCC).
- Integrated experience: Look for a partner with hands-on experience integrating complex systems into the confines of a container. They should have demonstrated the ability to design solutions that ensure compatibility and seamless operation between different components.
- Consulting capacity: A good manufacturer will act as a consultant, helping you analyze your project requirements and recommend the best technical solutions, rather than simply manufacturing from a ready-made drawing.
2. Flexible Customization Capability (OEM / ODM)
No two BESS projects are exactly alike. Each uses different batteries, PCS, transformers, and is installed in locations with unique environmental conditions. Therefore, flexible customization is a must.
- Tailored design: An ideal partner should have the ability to design and manufacture on demand (OEM/ODM), creating a container that is “tailored” to the exact equipment configuration and project requirements. This includes customizing dimensions, door locations, connection holes, and structural reinforcement.
- Space optimization and maintenance: Custom design allows for scientific equipment placement, optimizes cooling airflow, and creates reasonable space for future operation and maintenance.
- Meet special requirements: From integrating special safety systems to meeting aesthetic requirements, a capable custom manufacturer will ensure the final product meets every aspect of the project.
3. Strict Production Process and Quality Assurance
BESS containers are long-term assets, expected to last for decades in harsh environmental conditions. Therefore, manufacturing quality and quality control (QA/QC) processes are factors that cannot be overlooked.
- Compliance with international standards: Ensure the manufacturer complies with international standards for container construction such as ISO, with heavy-duty steel frames and sturdy construction.
- Clear quality process: Require manufacturers to clearly outline their quality control processes, from incoming material inspection, monitoring the quality of welds, to anti-corrosion coating processes and testing the tightness of finished containers.
- Material quality: A high quality container shell must be made from specialized steel and coated with a high-grade multi-layer paint system, capable of resisting corrosion in marine environments (C5), ensuring long-term durability.
4. Comprehensive Supply and Support Capabilities
The relationship with a manufacturer should not end when the product is delivered. A strategic partner will accompany you throughout the entire project lifecycle.
- Technical assistance: Look for a supplier with a technical team available to assist during installation, equipment integration, and on-site commissioning.
- Clear warranty policy: A comprehensive, transparent warranty policy covering both the structure and integrated systems is a testament to the manufacturer's confidence in the quality of their products.
- After-sales service: The ability to provide future maintenance, repair or upgrade services is a big plus, ensuring your system is always running in the best condition.
5. Strategic Advantages of “Made in Vietnam” Partners
In the context of the energy storage industry in Vietnam being formed and developed, choosing a local manufacturing partner brings significant competitive advantages.
- Optimize costs and time: Local manufacturing eliminates expensive international shipping costs and long lead times, helping to speed up project timelines and optimize investment flows.
- Understand local regulations: A “Made in Vietnam” partner will have a deep understanding of construction and fire prevention regulations and standards in Vietnam, helping the project licensing and approval process go more smoothly.
- Fast and flexible support: Geographical proximity allows for quick and efficient exchange, survey and technical support at the construction site.
- Promoting domestic supply chains: Choosing a domestic manufacturer not only benefits the project but also contributes to promoting the development of the supporting industry and Vietnam's self-reliance in energy technology.
