Energy Storage Harness
Energy Storage Cables are specialized conductors and connectors used in energy storage systems to transmit high-current DC power and low-voltage control signals. Unlike standard AC cables, energy storage cables are designed to withstand unidirectional DC stresses and frequent charge-discharge cycles without insulation breakdown or overheating. SUNKEAN offers pre-assembled energy storage wiring harnesses, providing cables and brand-compatible connectors to address on-site connection challenges for customer projects.SUNKEAN is a leading Chinese energy storage cable manufacturer, operating an 80,000-square-meter production base. In the energy storage sector, the company holds UL and TÜV certifications, ensuring high-quality production capabilities and rapid delivery times.

How to Choose the Right Cable Harness for ESS?
FAQ on Energy Storage Harness
How much voltage can energy storage cables handle?
Modern energy storage cables, such as UL 3816 or UL 3817 types, can support up to 3000V DC, making them ideal for large-scale energy storage applications like utility-scale batteries or grid-connected systems.
What are typical applications of energy storage harnesses?
Energy storage harnesses are used in containerized ESS units, battery clusters, inverter-battery connections, and power distribution panels—ensuring neat cable management and fast deployment.
How do energy storage cables improve system safety?
High-quality eletrical energy storage cables use flame-retardant, low-smoke, and halogen-free insulation materials. They reduce fire risk, resist oil/oxidation, and maintain flexibility under extreme temperatures, improving long-term operational safety and economy.
How should I choose the right energy storage cable or harness?
Consider voltage rating (up to 3000V), insulation material (like XLPO or PVC), flame resistance (e.g. VW-1), certification (UL, TUV), and application environment. For complex systems, customized harnesses ensure the best fit and reliability.
