The Growing Importance of Energy Storage Interconnects

Battery energy storage systems are transforming how power is generated, distributed, and consumed across residential, commercial, and industrial applications. These systems store energy and stabilise electrical performance in large grid installations, from medium commercial to residential establishments.

However, the success of any energy storage system depends heavily on the quality and reliability of its interconnect components. Poor connections can lead to power losses, safety hazards, and premature system failures. This is where Amphenol Energy Storage Interconnects have established themselves as industry leaders.

The energy storage market demands connectors that can handle extreme conditions while maintaining consistent performance. Whether the energy storage method is achieved through banks of battery packs, flywheels, thermal energy or hydroelectric systems, the right electrical interconnect solution is essential for your application.

Understanding Amphenol's Energy Storage Portfolio

Amphenol has developed a comprehensive range of interconnect solutions tailored specifically for energy storage applications. Their portfolio encompasses everything from compact signal connectors to high-power distribution systems capable of handling hundreds of amperes.

The Amphe-PRB series offers a balance of affordability and Amphenol's trusted reliability, specifically designed to meet the growing demands of industries such as energy storage, industrial automation, and alternative energy. This series addresses the unique challenge of providing robust connectivity while meeting strict cost constraints in high-volume applications.

For higher-specification requirements, Amphenol's industrial-grade solutions offer advanced features including aerospace-grade sealing materials, bidirectional shut-off valves, and stainless steel construction for extended durability in harsh operating conditions.

Critical Safety Standards for Energy Storage Connectors

Energy storage systems operate under stringent safety regulations due to the high energy densities and potential hazards involved. Understanding these standards is crucial for engineers selecting appropriate interconnect solutions.

UL 9540 is a comprehensive safety standard that covers electrical, electrochemical, mechanical and other types of energy storage technologies for systems intended to supply electrical energy. This standard sets rigorous requirements for electrical safety, thermal safety, mechanical safety, fire safety, system performance, system reliability, and system documentation.

The complementary UL 9540A standard specifically addresses thermal runaway testing, which is explicitly cited in NFPA 855 for large-scale fire testing and is the only national standard in the U.S. and Canada for fire safety testing methods for battery ESS.

Additional relevant standards include:

• NFPA 855: Standard for the Installation of Stationary Energy Storage Systems
• IEC 62933 series: Safety requirements for grid-integrated ESS systems
• IEEE 1547: Standards for interconnection with electric power systems

These standards mandate specific requirements for connector performance, including current-carrying capacity, temperature ratings, ingress protection, and arc fault protection capabilities.

Key Technical Specifications for ESS Connectors

Modern energy storage interconnects must meet demanding technical specifications to ensure reliable operation throughout the system lifecycle. Temperature performance is particularly critical, with many applications requiring operation from -40°C to +105°C to accommodate both outdoor installations and internal battery compartment conditions.

Current-carrying capacity varies significantly based on application requirements. Amphenol specialises in board-to-board, wire-to-board, and box-to-board interconnects, delivering exceptional performance up to and beyond 500 amps. This capability is essential for high-power energy storage systems where multiple battery modules must be connected in series or parallel configurations.

IP ratings are equally important, with IP67 being the minimum requirement for most outdoor installations. This rating ensures protection against dust ingress and temporary immersion in water, critical for solar-plus-storage installations and outdoor battery enclosures.

Applications Across Energy Storage Technologies

Amphenol Energy Storage Interconnects serve diverse applications across the energy storage ecosystem. In battery energy storage systems, connectors must handle the complex requirements of lithium-ion, flow batteries, and emerging technologies while providing safe disconnection capabilities for maintenance.

Solar array applications require connectors and advanced interconnect assemblies that can withstand environmental stresses while maintaining electrical performance. The combination of UV exposure, thermal cycling, and moisture ingress creates challenging operating conditions that demand specialised connector designs.

Grid-tie applications present additional complexities, requiring interconnects that can safely interface with utility-grade electrical systems while providing arc fault detection and rapid shutdown capabilities mandated by safety codes.

Industrial and commercial installations often require customised solutions that balance performance requirements with installation constraints. The Amphe-PRB series is particularly suited for energy storage systems, solar inverters and converters, where reliability and cost-efficiency are crucial.
