OEM Sensor Wire Harness — Custom Solutions by WinpowerCable

Solar Wire Harness Series

As a professional solar wire harness manufacturer, Danyang Winpower offers a wide range of products. The range of wire harnesses covers everything from connecting the PV modules to the energy storage system. Each product can be customized according to the actual working conditions. This includes wire gauge, color, jacket material, terminal type, and protection rating, ensuring a perfect fit for your system.

Harnesses for strings	Harnesses for Combiner Boxes	Inverter Wiring Harnesses
Usually used to link several PV modules in series and then parallel to a combiner box, it is appropriate for electrical connections between PV modules.	Connecting numerous component strings to a combiner box is the function of these wire segments.	Links a combiner box or battery bank to an inverter for high current/high voltage transmission, frequently necessitating EMI suppression and industrial-grade connection durability.
Features:MC4 or Amphenol waterproof connectors are included as standard. Temperature and UV-resistant TPE or XLPE sheathing Both single-conductor and two-conductor layouts are supported. To cut down on field wiring time, the wire length was customized with an accuracy of ±5mm. Relevant voltage: 1500V DC maximum Translated using the free edition of DeepL.com	Features:Integrating fuse holders, grounding wires, and quick disconnects is possible. Copper noses and ring terminals that are pre-assembled for customized end crimping Built with several cores, integrating control or monitoring signals is a breeze. Protective sheathing can be rated as flame and UV resistant (e.g., UL 94V-0).	Features:Support for large wire diameters: 4 AWG to 12 AWG Discretionary industrial connections (e.g., Anderson, Staubli, TE, etc.) Discretionary shielding to satisfy EMI/RFI protection standards Integration of ground wire (PE wire) is accessible.

Handles for Battery/ESS	Utilization of Integrated Solar Systems
For use in solar power systems that also incorporate energy storage, linking the BMS, PCS, and battery module.	To simplify field installations, increase system safety, and standardize wiring, system integrators and original equipment manufacturers can order complete wiring harness assemblies.
Features:Allows copper core harnesses with large currents (up to 200A) to function Allows for the integration of signal lines for temperature and voltage monitoring Adaptable wires featuring lithium interfaces and several connections The battery compartments are compatible with high sealing ratings (IP67/IP68).	Features:Turnkey solutions for electrical wiring based on computer-aided design (CAD) schematics and 3D models Items such as heat shrink tubing, pre-assembled labels, and guide clips Clear color coding and an established orientation for the user interface You have the choice between modular or one-piece wiring.

The Solar Wire Harness Manufacturer offers bespoke solar wire harnesses.

Supports a range of wire gauges (AWGs) from 4 to 18, making it appropriate for a variety of current ratings.
The insulator and conductor are made of high-conductivity copper. Materials for sheathing: XLPE, PVC, TPE, and specific materials that are resistant to direct sunlight.

This includes MC4, Amphenol H4, Anderson, TE, Molex, and many more types of connectors and terminals. Battery interface connectors, ring terminals, fork terminals, copper noses, and more options are available.
Environmental adaptation and protection level: Protective sheaths up to IP65, IP67, and IP68. You have the option to include a UV stabilized layer, anti-rodent bite braid, and tensile strength reinforcement.
Using color coding and printing labels: Depending on the needs of the client, cables can be colored in a variety of ways, such as red, black, blue, or yellow. Assist in identifying items by providing heat-shrinkable labels, spray-code printing, numbered ties, and more.
