Technology Overview

What Is an MC4 Connector?

An MC4 connector is the industry-standard single-pole DC connector used to join PV module leads, extension cables and inverter DC inputs. ShineTong supplies MC4-compatible connectors as a manufacturer-facing wholesaler for export markets that need consistent packing, cable sizing and branch options.

A properly specified pair typically includes keyed male/female housings, tin-plated copper contacts, PPO/PPE insulation, and an IP68 seal when fully mated. Voltage class (1000V or 1500V DC) and current rating must match string design and cable cross-section.

For distributors and EPCs, connector choice affects field failure rate, warranty exposure and installation speed - especially when mixing module brands or using parallel branch connectors.

How MC4 Connectors Fit a PV String

From module output to inverter DC input - where wholesale connector SKUs are used.

1

Module Output

Factory module leads terminate in male/female MC4-style plugs. Field replacements must match polarity and contact geometry.

2

Extension / Homogeneous Run

Pre-crimped or field-crimped MC4 pairs extend DC runs between arrays, roof penetrations and combiner inputs.

3

Branch Parallel

T-type or Y-branch connectors parallel two strings into one feed where design allows - check fuse and inverter limits.

4

Inverter / Combiner Input

Final mated connection enters the combiner box or inverter DC terminals with correct voltage and current rating.

Why ShineTong

Built for Distributor & EPC Buying

Practical buying points for MC4 connector wholesale - not a thin product copy page.

01

Manufacturer / Supplier Path

Quote factory-direct packing for wholesalers who need stable SKUs across 1000V and 1500V projects.

02

IP68 Mating Seal

Outdoor PV runs need dust and water protection when connectors are fully mated and correctly assembled.

03

Cable Cross-Section Match

Stock 2.5 / 4 / 6 / 10 mm² options so installers are not forced into wrong crimp diameters on site.

04

Branch Connector Options

T-type and Y-branch SKUs support parallel layouts where string combiners are not the preferred BOM.

05

Compatibility Discipline

We position connectors as MC4-compatible unless a specific approved pairing is requested - reducing warranty disputes.

06

OEM / Private Label

Carton labels, bag prints and mixed kits can follow your brand guidelines for destination-market wholesale.

FAQ

Frequently Asked Questions

Are ShineTong connectors original MC4 or MC4-compatible? v
We supply MC4-compatible connectors for wholesale and project packing unless you specify an approved brand pairing. Always verify mechanical and electrical compatibility with the module connectors used on site.
What voltage and current ratings do you supply? v
Common options cover 1000V DC and 1500V DC, with current ratings typically 30A to 50A depending on contact design and cable cross-section (2.5 / 4 / 6 / 10 mm²).
Do you supply T-type and Y-branch connectors? v
Yes. We quote T-type and Y-branch MC4-compatible parallel connectors for string combining on rooftop and ground-mount projects. Share the required polarity layout and quantity.
What is the typical MOQ for wholesale MC4 connectors? v
Sample and trial cartons are available for new distributor partners. Stocking MOQ depends on SKU mix (pairs, T-branch, Y-branch) and packing method - confirm on quotation.
Can you OEM private-label packing? v
Yes. Distributors often request bag labels, carton marks and mixed kits under their brand. Provide artwork guidelines with your RFQ.
