High-Quality BESS Container Manufacturing: TLS Energy’s Commitment to Excellence

As the global demand for Battery Energy Storage Systems (BESS) rises, the importance of high-quality container and enclosure manufacturing becomes critical. These containers are not simple structures—they are complex, integrated units that house high-voltage batteries, PCS systems, fire suppression, and HVAC. TLS Energy specializes in custom BESS containers and enclosures, and we place strict quality control at the core of our manufacturing process to ensure safety, reliability, and long-term performance.

Why Quality Control Is Crucial for BESS Enclosures
A well-designed and properly manufactured container is essential to protect battery systems from environmental hazards, mechanical stress, and thermal fluctuations. Poor-quality enclosures can lead to water ingress, temperature imbalance, fire risks, and even system failure.
At TLS Energy, we understand the stakes. That’s why every container we deliver undergoes a rigorous, multi-stage quality control process—from raw material sourcing to final structural and system testing.

TLS Energy’s Quality Control Process for BESS Containers
    1.    Certified Material Selection
We begin with raw materials that meet international safety and durability standards. All steel, fireproof panels, insulation materials, and paint coatings are tested for strength, corrosion resistance, and fire performance. Only materials with full traceability and compliance certificates are accepted for production.
    2.    High-Precision Welding and Structural Integrity
Welding is a critical part of the container manufacturing process. TLS Energy uses qualified welders and follows a controlled welding procedure to ensure consistent joint strength across all parts of the structure. Weld seams are visually inspected and further tested using non-destructive testing (NDT) methods to identify any hidden flaws such as cracks or porosity.
    3.    Container Load Testing and Strength Verification
To verify the structural integrity of the enclosure, each unit undergoes a load test to simulate real-world transportation and stacking scenarios. This test confirms the container’s ability to handle heavy equipment loads and withstand harsh handling during shipping and installation. Reinforced base frames, lifting points, and corner castings are tested under full load conditions.
    4.    Thermal Performance and Environmental Protection
TLS Energy tests every enclosure for thermal insulation efficiency, ensuring the container maintains stable internal temperatures even in extreme climates. We also conduct IP (Ingress Protection) testing to confirm resistance to dust, water, and salt fog exposure, especially for coastal or desert deployments.
    5.    Integrated Systems Inspection and Safety Validation
All fire suppression systems, electrical wiring, HVAC, sensors, and auxiliary systems are installed according to project specifications and applicable codes. Before delivery, we carry out a full inspection of all electrical and mechanical integration points, including continuity checks, ground bonding, and safety system triggers.
    6.    Final Quality Audit Before Shipping
Every BESS container is subjected to a comprehensive final quality audit. This includes structural review, system integration confirmation, environmental sealing checks, and full documentation of all test results. Only after meeting all internal standards and client requirements will the product be approved for shipment.

Reliable, Safe, and Built to Last
TLS Energy’s strict quality control ensures that every BESS container or enclosure is reliable, compliant, and ready for long-term operation in the field. Our team is dedicated to providing high-quality, custom-engineered energy storage solutions that meet the highest standards of safety, performance, and durability.
