Solar Harness & PV Cable Assembly | MC4 Y-Branch

Solar harnesses and PV cable assemblies: MC4-compatible extensions, Y-branch pairs and string harnesses on TUV PV1-F, H1Z2Z2-K or UL 4703 wire.

Photovoltaic solar harness with quick-lock solar connectors
Made to drawing. No prices are published and there is no cart. Send the drawing, a sample or a list of from-to points and we will quote the wire, connector, crimp and test method in writing.

Photovoltaic (Solar) Harness: what we build

A solar harness lives outdoors for twenty-five years, so the decisions that matter are the ones that survive weather rather than the ones that look good on a drawing. The wire is cross-linked, halogen-free and UV-stabilised; the connector is mated to the same series on the panel side; and the crimp is pull-tested because a loose MC4 joint is a hot spot waiting to happen.

The wire we build on is the same TUV and UL photovoltaic line already documented in this catalogue. Where a project has to satisfy EN 50618 the harness carries H1Z2Z2-K; where the approval is TUV 2 PfG 1169 it carries PV1-F; where the array is North American and UL 4703 governs, it carries the UL PV wire. Naming the standard on the drawing is enough for us to select the right one.

Y-branch pairs, four-way and six-way string harnesses, extension leads and fused branches are assembled and tested as complete parts, so the string is terminated once on site rather than field-fitted.

How we build it

  • MC4-compatible extension leads in the lengths your string actually needs
  • Y-branch pairs and multi-way string harnesses built as one tested part
  • Inline fuse holders and fused branch assemblies integrated where required
  • Double-insulated, halogen-free jacket on every PV wire we use
  • Polarity check and pull-test on each terminated end before packing
  • Wire selected to EN 50618, 2 PfG 1169, IEC 62930 or UL 4703 to match the project

Wire we build this harness on

Every conductor is Xinya wire from this site's own catalogue, so the style inside the harness can be traced to a published data sheet. These are the lines most often specified for this application:

If your drawing names a style that is not listed here, ask — the catalogue published on this site is a subset of what the factory runs, and we can quote against a style number as easily as against a description.

How to get a quotation

Send the drawing, the sample, a photograph with a scale in shot, or a table of from-to points. Our reply names the wire style, the connector series, the crimp specification, the sleeving and the test method, so your engineers can approve the part rather than interpret a description. Nothing on this site carries a price: every harness is quoted against the specification you provide.

Questions buyers ask about photovoltaic (solar) harness

Which is the right PV wire for a European project?

EN 50618 defines the cable type H1Z2Z2-K, which is what most European tenders name; TUV 2 PfG 1169 defines PV1-F, which is the older but still widely specified designation. Both are cross-linked, halogen-free and 1.5 kV DC rated, and both are listed in this catalogue under the TUV PV wire series.

Do you supply Y-branch connectors already assembled?

Yes. A Y-branch pair or a multi-way string harness is crimped, tested and supplied as one part, which removes a field joint and a field mistake from the installation.

Can the harness carry an inline fuse?

Fuse holders are integrated where the design needs them. Tell us the fuse rating and the connector series and they are assembled into the harness rather than added afterwards.

What sizes do you build in?

2.5 mm² to 16 mm² is the normal span, which covers 14 AWG to 6 AWG — the range that matches the TUV PV lines in this catalogue.

Is the connector on the panel side compatible?

We build to the MC4-compatible series, which mates with the connectors broadly used on modules. If your module supplier uses a proprietary interface, send the mating part number and we will build to it.

Questions & answers

Frequently asked questions

Certifications, lead time, payment, shipping and MOQ — the points buyers ask about most often. If something is still unclear, send us your requirement and we will answer directly. See the full FAQ →

01 Are you a manufacturer or a trading company?

We are a wire harness manufacturer — cutting, stripping, crimping, sealing and testing are all carried out in-house at our Suzhou plant. We are also an authorised distributor of Xinya brand electronic wire, so you can source both the wire and the finished harness from one supplier.

02 What certifications do your electronic wires have?

Our electronic wires carry UL, VDE, PSE and CE approvals, together with RoHS and REACH compliance for the European market; TUV approvals are available for PV and renewable-energy wire. Certificates and test reports are issued by the manufacturer and can be supplied with your quotation on request.

03 How long is the lead time?

For electronic wire, popular styles such as UL1007, UL1015, UL1061 and UL1569 are normally available quickly; other styles, non-standard colours and cut lengths usually take around 7 days. Wire harnesses are made to order, so the schedule depends on your drawing, connector availability and quantity — we confirm it in the quotation.

04 What are your payment terms?

We commonly accept T/T (telegraphic transfer), PayPal and Western Union. Typically a 30% deposit is required before production, with the balance paid before shipment.

05 How do you ship the goods?

Samples and small orders are shipped by international express (DHL, FedEx, UPS, TNT) or by air freight. Larger orders normally go by sea to reduce freight cost. We can quote EXW, FOB, CIF or door-to-door terms and will recommend the option that best fits your budget and delivery date.

06 Do you have a minimum order quantity (MOQ)?

We keep a low MOQ to support your business. Generally the MOQ is 1 piece for standard models, although it may vary slightly for customised products. Small trial orders are welcome.

07 Can you build harnesses to our own drawing or sample?

Yes. We build to print and build to sample — send us a 2D drawing, a BOM, connector part numbers or even a photo of the part in use, and we will assemble, test and quote accordingly.

08 Can I get a sample before placing a bulk order?

Yes. We are happy to build a prototype first so that you can approve the fit, crimp and finish before committing to volume. Send the drawing and the target quantity and we will quote sample cost and lead time.

09 What information do you need to give a quotation?

For wire: the style or UL number, AWG, voltage and temperature rating, insulation, conductor, colour and length. For harnesses: the drawing or BOM, connector brand and part number, terminal and housing type, wire specification, cut length and tolerance, sleeving or tubing, label and packaging requirements, quantity and destination. If anything is unclear we will ask — or propose a construction for you.

10 Do you support OEM / ODM and private labelling?

Yes. We work with customer-specified connectors and brands as well as JST, Molex and HongXing, and can add printed markers, custom labels, printed bags and your own carton artwork for OEM and ODM projects.

11 How do you control quality?

Every order goes through incoming wire inspection, cutting and stripping checks, crimp height and terminal pull-force testing, 100% continuity and open-and-short testing, and a final dimensional and visual inspection. Inspection records can be supplied with the shipment when your project requires them.

12 Can you help with wire and connector selection?

Yes — our engineers help match wire gauge, insulation and temperature rating to your current, voltage and working environment, and select a terminal and housing combination that crimps reliably. Describe the application or send a sample and we will propose a construction.

13 Can you supply cut lengths and custom packaging?

Yes. Wire can be supplied in cut lengths, coils or spools, with PE bags, cartons, pallets and printed labels arranged to suit your warehouse or production line.

14 Do you ship worldwide, and can I visit the factory?

We ship worldwide, with regular shipments to Europe, North America, South-East Asia, the Middle East and Australia. You are welcome to visit our plant in Suzhou, and you can see our production lines in the factory videos on this site.

15 What happens if there is a quality problem after delivery?

Contact us with the order or batch number and photos of the issue. We will check it against our production and inspection records and, where the fault is confirmed on our side, arrange replacement or credit.
