Delta Presents Next-generation Energy Storage System in Containerized Modular Design

New product focuses on anticipating industry challenges, enabling increased return on investment through cost savings and comprehensive risk management

Delta, a global leader in power and energy management, introduces the new LFP battery system: a containerized energy storage system that is tailored for megawatt-scale energy storage applications such as solar energy shifting and ancillary services. This new battery system from Delta is designed to address challenges such as rising construction costs, limited space, and safety issues, while balancing the effort on site, risk management and long-term success.

Flexible energy storage solution combines efficiency with safety
The new battery system, housed in a standard 10-foot container, simplifies and shortens installation with its positioning tolerance and enclosed cable design. Key safety features include the use of LFP (lithium iron phosphate) cells, comprehensive monitoring of each individual battery cell, redundant sensors, fire-resistant materials, and a built-in sprinkler system. Together, these safety features significantly reduce the risk of thermal runaway and provide robust system protection by ensuring a rapid response to potential fire hazards with effective prevention of heat spread.

Meeting challenges safely
“With the increasing scale of energy storage projects and the diversification of applications, owners’ expectations for installation efficiency and system completeness will continue to rise,” explains Jim Chen, Vice General Manager of Delta’s Energy System Solutions Business. “Delta’s goal is to provide a battery system that takes into account a comprehensive range of relevant factors, including a balance between cost and safety. Accordingly, we can overcome challenges from planning to operation. This not only improves the ROI of our customers, but also considers sustainability and other social interests. The battery system not only reflects Delta’s accumulated experience in the field of energy storage, but also underlines our commitment to make a valuable contribution to the continuous development of the industry,” adds Jim Chen.

Key features of a containerized energy storage system

• The battery system sets new standards for flexibility, efficiency, and safety in the industrial environment. With capacity configurations ranging from 708 kWh to 7.78 MWh, the solution can be seamlessly integrated with site controllers, UPS and other system components. This flexibility optimizes space utilization, as no additional cabinets are required.
• Thanks to the ability to transport the entire container without removing the battery modules, the battery syste also enables efficient on-site operation: flexible dust connectors between the containers enable easy positioning and prevent redundant lifting. In addition, lateral cable entries eliminate the need to dig trenches, thus increasing the efficiency of installation and cabling. On-site installation without opening the battery compartment protects the system from moisture and dust.
• Delta relies on lithium iron phosphate (LFP) cells as the central component for increased safety and longevity. Each cell is comprehensively monitored for greater safety and a longer service life. Active protection mechanisms are an integral part of the system to minimize the risk of thermal runaway. Multiple environmental monitoring and protection features also enable a timely response to potential fires, while fire-resistant materials and optional sprinkler systems control the spread of heat, limiting damage in the event of a disaster.
• The integrated proactive cell-balancing technology improves battery stability by performing dynamic cell balancing while charging and discharging to increase system discharge capacity. Delta’s advanced battery management system (BMS) ensures fast communication response and real-time data exchange to maintain the operational reliability of the system. Redundant sensing and communications ensure that the system always remains controllable to safely achieve high performance.
