Abstract：As global energy storage projects continue to scale rapidly, owners and system integrators are facing a practical challenge: how to shorten project delivery cycles and reduce on-site installation complexity while ensuring system safety and reliability.

To address this demand, TLS introduces a Semi-Integrated Energy Storage Container solution, where key auxiliary systems are pre-installed and tested in the factory. This significantly reduces on-site workload and improves overall deployment efficiency.

This article focuses on answering the following key questions:

• Which systems are suitable for factory pre-integration?
• How does a semi-integrated solution shorten project delivery time?
• How can flexible customization be achieved for different project requirements?

By understanding the design philosophy and delivery model of semi-integrated energy storage containers, users can better evaluate the most suitable solution for their projects.

1. Factory Pre-Integration: Improving Project Deployment Efficiency

On-site construction for energy storage projects is often constrained by schedule pressure, environmental conditions, and labor availability.
Through factory pre-integration, key auxiliary systems can be installed and tested in advance.

Typical Pre-Installed Systems Include:

• HVAC (Thermal Management System)

Industrial-grade air conditioning systems are configured according to project requirements, ensuring a stable operating environment for battery systems.

• Fire Suppression System (Project-Specific Configuration)

Fire detection and suppression systems can be pre-installed or reserved based on customer requirements, enhancing overall system safety.

• Lighting System

Internal lighting systems support inspection, maintenance, and daily operational management.
Compared with on-site installation, factory pre-integration ensures higher consistency and significantly reduces installation time at the project site.

2. From Design to Delivery: A Complete Project Execution Workflow

The success of an energy storage project depends not only on equipment quality, but also on execution efficiency across the entire delivery chain.
TLS provides end-to-end project support covering the full lifecycle.
System Design PhaseBased on project requirements, TLS performs:

• Container layout design
• Thermal management system planning
• Electrical interface design
• Auxiliary system configuration

This ensures full alignment with real application scenarios.

Manufacturing and Integration PhaseIn the factory, TLS completes:

• HVAC installation
• Cable tray installation
• Power distribution pre-arrangement
• Fire system pre-integration
• Structural component assembly

This improves manufacturing quality and ensures consistent delivery standards.

Factory Acceptance Testing (FAT)Before shipment, system validation tests are conducted, including:

• HVAC performance testing
• Electrical system inspection
• Auxiliary equipment functionality checks

This significantly reduces commissioning risks at the project site.

3. Flexible Customization for Different Energy Storage Projects

Energy storage projects vary widely in technical requirements, including:

• Different battery technologies
• Different electrical architectures
• Different environmental conditions
• Different owner standards

Therefore, energy storage containers must offer strong customization capabilities.

TLS Supports Flexible Adjustments in the Following Areas:Container Size and Layout
​
Optimized internal space design based on equipment dimensions and maintenance requirements.

• HVAC Configuration

Cooling or heating capacity tailored to local climate conditions.

• Fire Protection System Design

Customized fire safety solutions based on project specifications.

• Electrical and Communication Interfaces

Compatible with different PCS, EMS, and BMS integration requirements.

This flexibility allows a standardized platform to be adapted to a wide range of energy storage applications.

4. Balancing Efficiency and Sustainability

Energy storage systems play a key role in global energy transition.

TLS also integrates sustainability principles into its design and manufacturing process:

• Improving energy efficiency of auxiliary systems
• Optimizing material utilization
• Reducing on-site construction waste
• Supporting renewable energy infrastructure development

Through optimized engineering and manufacturing workflows, TLS helps customers achieve more efficient and sustainable project delivery.

Conclusion: Why Are More Projects Choosing Semi-Integrated Solutions?

For many energy storage projects, the real challenge is not only selecting equipment, but balancing delivery efficiency with system flexibility.

Semi-integrated energy storage containers provide this balance.

They reduce on-site installation workload through factory pre-integration while maintaining flexibility for different system configurations.

Key Selection Considerations:

• Reduced on-site installation workload: Lower construction complexity and schedule risk
• Fast deployment capability: Shorter project execution timelines
• High customization flexibility: Adaptable to different technical standards
• Factory-tested reliability: Improved quality and operational stability
• Full project support capability: End-to-end design, manufacturing, testing, and delivery support

Through systematic engineering design, TLS semi-integrated energy storage containers evolve from traditional container products into high-efficiency project delivery platforms, providing a solid foundation for modern energy storage applications.
