Custom Manufacturer of Household and Outdoor Energy Storage Wire Harnesses

We have specialized in the energy storage field for over 10 years, with a deep understanding of the core requirements for residential energy storage and portable power systems—safety, durability, and plug-and-play reliability.
Designed for real-world applications: Our harness solutions are optimized for limited installation space and outdoor environments, balancing compact layouts with long-term environmental resistance.
Complete connectivity: From battery modules and BMS to inverters, we provide end-to-end custom wire harness solutions to ensure stable power and signal transmission throughout the system.
Reliability built into the system: Supported by patented technologies, an ISO 9001 quality system, and 100% inspection, we deliver harnesses with consistent performance and dependable safety.
A focused OEM partner: We manufacture strictly to your drawings and specifications and offer manufacturability analysis—acting as a reliable extension of your production capability.

Product Advantages

Providing reliable connections for home and outdoor energy storage is our focus. We understand that overseas customers are most concerned about long-term safety and stable operation in various environments.
Our product advantages come from a practical response to these needs:

Flexible Customization, Precise Matching: Wire length, specifications, and connectors can be flexibly adjusted according to your system’s power and installation space, ensuring a perfect fit.
OEM Focus, Consistent Quality: We strictly manufacture according to your drawings, focused on realizing your design, and guarantee consistent quality from prototypes to batch delivery.
Rigorous Testing, Safety Assured: Every wire harness must pass a series of tests including continuity, high-voltage performance, and insulation resistance before leaving our factory, ensuring safety compliance.
Standards First, Reliable & Durable: Our products comply with the RoHS directive and strictly adhere to the WHMA-A-620 cable assembly acceptance standard and UL 817 connector safety standard. Produced under an ISO 9001 quality management system, they utilize weather-resistant materials and sealed designs to withstand outdoor challenges like temperature extremes and humidity.
Controlled Cost, On-Time Delivery: Our automated production lines increase efficiency and ensure consistent quality while effectively reducing unit costs. Combined with standardized processes and flexible production capacity, we can respond quickly to demand and deliver on time.

Reliability Test Reports

At Yundian, all wire harnesses undergo rigorous quality and electrical testing prior to shipment, ensuring compliance with customer drawings and technical specifications.
