Introduction of BESS Container Testing System
As grid-scale energy storage projects grow in size and complexity, testing at only cell, module, or rack level is no longer enough. Once multiple racks are integrated into a container, new risks appear in wiring, communication, cooling, and system coordination. Semco Infratech’s BESS Container Testing System is engineered to address exactly this challenge, giving manufacturers a reliable way to validate containerised battery systems before they leave the factory. This solution is purpose-built for modern energy storage manufacturing, where uptime, safety, and traceability are non-negotiable.
Why Container-Level Testing Matters

Pack and rack tests confirm that individual units perform correctly, but a container operates as a unified system. Inside the container, cables, busbars, protection devices, EMS/BMS communication and thermal management all interact. Any mismatch can lead to circulating currents, hot spots, or unstable behaviour under dynamic grid conditions. Container-level testing exposes these issues in a controlled environment rather than in the field. By simulating real operating profiles, manufacturers can validate performance, safety, and efficiency across the full container, not just isolated components. That makes container testing an essential part of any modern Container Assembly Line.
Key Capabilities of Semco’s BESS Container Testing System

Semco Infratech has designed its system as an all-in-one platform for charge and discharge testing of energy storage battery clusters and DC cabins. Available models include 2.5 MW, 3.2 MW, 3.6 MW and 5 MW, allowing seamless integration into different production capacities. One system supports both cluster-level and full DC cabin tests, enabling precise diagnosis of inter-cluster imbalance and circulating currents. An innovative back-to-back topology lets the tester charge one DC cabin while discharging another, creating a closed energy loop that dramatically reduces grid power draw and operating cost. Live monitoring of voltage, current, power, temperature and capacity provides deep visibility into system behaviour.
Designed for Modern BESS Production Lines

Semco’s solution fits directly into a BESS Container Assembly Line or ESS integration facility. The compact, integrated structure supports both indoor and outdoor installation, so it can be placed close to production or final inspection areas. Full-cycle test modes—capacity, C-rate performance, cycle life and stress profiles—allow engineering, production and quality teams to use the same platform for validation and mass-production QA. Smart auto-test software records every step, generates standardised test reports and supports long-term data traceability. This gives manufacturers a solid digital record for warranty support, grid-code compliance, and customer audits.
Conclusion of BESS Container Testing System
For energy storage manufacturers, container-level validation is no longer optional. It is the final, decisive step that confirms an integrated BESS container is safe, efficient and ready for long-term operation in demanding grid environments. Semco Infratech’s BESS Container Testing System delivers that assurance with high-power, energy-saving back-to-back testing, flexible installation and intelligent automation. By integrating this system into your production flow, you strengthen quality control, cut operating costs and boost confidence in every container you ship—making your manufacturing line, and your business, more competitive in the rapidly expanding world of utility-scale battery storage.
