Why Choose PVLinkTech as Your Waterproof Connector Factory?
Connector problems often start with the wrong supplier. Low-cost middlemen can lead to delays, inconsistent quality, and poor technical support. PVLinkTech controls tooling, molding, stamping, assembly, and testing in-house at our Shenzhen factory. When you ask a technical question, you get answers directly from the engineers who make your connectors.
A Real Manufacturer, Not a Middleman
A trading company can quote fast. It cannot make a connector in 3 days.
PVLinkTech can.

30+
In-House R&D Engineers
100%
In-House Production
Our in-house mold shop, injection molding lines, metal stamping, and automated assembly cover the full process from raw material to finished product. Need a sample? You get one in 3 days. Need a new mold? Tooling is ready in 20 days. That kind of timing only works when the tooling, machines, and engineers sit in the same building.
The R&D team has more than 30 engineers with close to ten years of connector experience. PVLinkTech is a certified National High-Tech Enterprise. We do not repackage someone else’s catalog. We design, mold, test, and produce our own products.
How do you tell a real waterproof connector factory from a middleman before ordering? Three questions usually settle it:
How fast can they produce a sample?
3 Days
Do they own their molds?
YES
Can you walk the floor on video call?
YES

Mass Production
One-stop, from your idea to a finished connector on your production line. For OEM waterproof connector projects, the same factory that makes our standard series builds yours.
Car-Grade Quality System
A waterproof connector factory is only as strong as the system behind it. In 2024, PVLinkTech passed IATF 16949, the automotive quality management standard. It is the same system car makers apply to their own supply chains, and we apply it to every connector we ship.
System certifications: IATF 16949, ISO 9001, ISO 13485, ISO 14001.
Product certifications: UL, cUL, TUV, UKCA, CE, SAA, CQC, RoHS.
IP ratings follow the international IP Code, and they are tested, not claimed. IP67 means protected against dust ingress and temporary immersion. IP68 means the connector survives continuous immersion under defined depth and time. Our series carry IP67 or IP68 ratings depending on the family, and the lab verifies them with actual water tests, not paperwork.
Testing runs in our own laboratory, built to UL and TUV standards, with 20+ pieces of testing equipment and a quality team of more than ten people. The lab covers the tests that matter for a connector in the field: insertion and extraction cycles, temperature rise and current, dielectric voltage, plug-in force, DC and insulation resistance, IP68 water immersion, glow-wire, leakage tracking, flame resistance, and temperature and humidity cycling.
Every order passes five inspection points: incoming raw material, material on receipt, production in process, warehousing, and final delivery. Each checkpoint is a chance to catch a problem before it reaches your line. The rule here is simple: more inspections, fewer surprises.

One Source for Solar, Energy Storage and Waterproof Connections
A solar or energy storage project requires more than one type of connector. PV modules need reliable DC connections, battery systems require high-current interfaces, and outdoor equipment depends on sealed power distribution and surge protection.
PVLinkTech brings these requirements together through one engineering and manufacturing partner, helping project buyers simplify supplier coordination, technical documentation, sample validation and production follow-up.
Our core product portfolio includes:
- Energy Storage Connectors: High-current connector solutions for battery modules, racks, cabinets and power conversion systems, with multiple current ratings and cable-entry configurations available.
- MC4 and PV4 Solar Connectors: Outdoor DC connector solutions for residential, commercial and utility-scale photovoltaic systems, with configurations rated up to 1,500 V DC.
- Battery Busbar Connectors: High-current connection solutions for battery packs, busbars, power distribution units and energy storage equipment.
- Screwless Waterproof Connectors: Tool-free wiring solutions for outdoor lighting, electrical installations and equipment requiring fast field assembly.
- Screw Waterproof Connectors: Threaded IP-rated connectors designed for secure cable connections in outdoor lighting and industrial applications.
- IP68 Waterproof Junction Boxes: Multi-way waterproof enclosures for outdoor cable branching, power distribution and protected electrical connections.
- LED Surge Protective Devices: 10 kV and 20 kV surge protection options for outdoor LED lighting, streetlights and related power equipment.
PVLinkTech also supports custom cable lengths, terminal configurations, connector colours, labels, packaging and project-specific cable assemblies. Samples and technical drawings are available to help your team verify electrical ratings, cable fit, sealing performance and installation requirements before volume production.
Protection ratings, electrical specifications, certifications and operating temperatures vary by product series and configuration. Please confirm the applicable datasheet and certification documents before final product selection.The main series runs from -40 to +85 degrees C, with gold-plated contacts rated to 1,900+ mating cycles. That performance range is why the same manufacturer shows up in solar farms, street lighting, stage lighting, EV charging, and radar systems. Buyers who need one IP68 connector supplier for multiple projects find the whole range in a single datasheet set.

What Installers and Engineers Say
“Grabbed a bulk order of these IP68 waterproof connectors for a commercial outdoor lighting project last month. We’ve had some crazy heavy rain since, and they’ve held up perfectly. Solid build quality, and the threading is as smooth as butter.”
“Swapped out our old MC4 connectors for PVLinkTech after dealing with constant sealing failures from a cheaper brand. The locking mechanism on these feels ten times more secure. Will definitely be reordering for our next solar farm.”
The reviews sit on top of real deployments:
a 120 MW floating and ground-mount solar project,
5 MW / 10 MWh containerized ESS cabinet wiring,
outdoor heavy equipment control and signal systems,
and a 200 MW desert solar park.

Frequently Asked Questions
If you are comparing waterproof connector factories, these are the questions buyers ask us most.
Q1What is your minimum order quantity?
Standard products start from 1 piece for evaluation, prototypes, and replacement needs. Volume pricing depends on the series and quantity, so tell us your target volume, and we will quote accordingly.
Q2Is every batch inspected before shipment?
Yes. Every order passes five inspection points: incoming raw material, material on receipt, in-process checks, warehousing, and final delivery. Our own laboratory, built to UL and TUV standards, runs 20+ testing stations.
Q3What are your lead times?
Standard bulk orders are typically ready in 3 to 5 business days. Custom tooling takes 20 days, with prototypes available in 3 days while the mold is in production.
Q4Can we visit the factory or do a video audit?
Both. The factory is in Guangming, Shenzhen, with 6,800 square meters of floor space. Overseas buyers are welcome to arrange a video walkthrough of molding, assembly, and testing.
Q5Do you support custom branding and cable assemblies?
Yes. OEM and ODM cover cable assemblies, wiring configurations, colors, logo marking, labels, and packaging. New molds take 20 days for tooling.
Q6What happens if a batch has quality issues?
Contact Ryan at ✉ [email protected] with the batch number.
◆ You reach the factory directly, not a reseller, so the issue is reviewed by our engineers, and a replacement is arranged without going through a chain.
