Goodwe-Style Plum-Blossom 6-Pin Female Solder-Wire Connector, Full Tin-Plated with Plastic Three-Piece Kit: Red Sealing O-Ring, Cable Gland Sleeve, Black Waterproof O-Ring

This Goodwe-Style plum-blossom 6-pin female solder-wire waterproof connector is purpose-built for Goodwe photovoltaic inverters, energy-storage cabinets and distributed solar power systems. It is fully equipped with a complete plastic three-piece kit: red waterproof O-ring, cable-clamping gland sleeve and black waterproof O-ring. Designed as cable-side female receptacle for field assembly, it effectively solves common industry pain-points such as insufficient dual-end sealing, poor cable strain-relief, difficult on-site harness processing, poor solderability and high production cost for solar equipment OEMs and harness manufacturers.

First of all, complete plastic three-piece kit delivers dual-end IP67 sealing performance for mating interface and cable entry end. Many comparable circular connectors on the market supply sealing parts separately, which easily causes missing accessories, mis-assembly and loss of waterproof performance. This Goodwe-style female connector comes with full-set original accessories: red silicone O-ring seals the plug-in mating surface; black silicone O-ring cooperates with plastic cable-clamping gland sleeve to compress cable outer sheath at cable-entry end. After tightening the rear gland nut, the cable-clamping sleeve evenly squeezes the black O-ring to wrap tightly around cable outer jacket, blocking dust, rainwater and humid moisture from invading into connector interior through cable gap. Dual-sealing design greatly improves environmental adaptability for outdoor installation scenarios. The cable-clamping gland sleeve also provides powerful strain-relief function, transferring pulling and twisting force from external cable to connector housing instead of delicate solder joints, avoiding solder joint fracture caused by cable dragging and vibration.

Second, full tin-plated female contacts realize superior solderability and cost-effective stable performance. Female sockets adopt high-conductivity copper alloy substrate with full-surface tin-plated treatment. Tin-plating has excellent soldering wetting property. Harness workshops can form reliable solder joints with ordinary soldering stations, effectively reducing virtual-solder and cold-solder defects during mass harness production. Under conventional indoor and semi-outdoor photovoltaic working environments, full tin-plated contacts maintain low and stable contact resistance, fully satisfying mixed transmission of power supply and monitoring signal for inverters and energy-storage cabinets. Compared with gold-plated solutions, full tin-plated configuration cuts down component procurement cost significantly, making it an economical and reliable choice for large-volume solar projects.

Third, solder-wire termination structure enhances harness-making flexibility and lowers production-tooling threshold. This female receptacle adopts solder-wire tail design instead of crimp-type contacts. Harness factories do not need to invest in expensive automatic crimping machines and special crimping dies. R&D prototype verification, small-batch trial-production and mass-volume manufacturing can all be completed by manual or semi-automatic soldering equipment. According to actual current load and wiring-space limitation, customers can select stranded copper wires within AWG22-16 range, free from constraints of fixed crimp terminal specifications. Field-assembly feature allows users to process harness length on-site without pre-ordered fixed-length molded cables, shortening new-product development cycle and improving construction flexibility for distributed photovoltaic projects.

Fourth, plum-blossom 6-pin circular layout plus anti-mis-mating polarization improves on-site construction safety. Unique plum-blossom 6-pin circular layout realizes compact integration of multi-channel power and signal circuits, saving installation space for inverter and energy-storage equipment. Built-in anti-mis-mating polarization keying on housing ensures only one correct mating angle. Field installers cannot complete plug-in under reversed orientation, effectively preventing contact bending, short-circuit and equipment damage caused by human mis-operation. High-grade PA66 flame-retardant housing possesses outstanding impact-resistance and UV-aging-resistance. When deployed in open-air photovoltaic sites, it resists cracking, embrittlement and fading under long-term sunlight irradiation and wide temperature swing. Internal insert firmly locks six female sockets, preventing contact shifting or loosening under mechanical shock and vibration.

Fifth, strict full-process quality control guarantees batch-to-batch consistency. Each production batch undergoes multi-level inspection before shipment: raw-material incoming inspection, tin-plating thickness sampling test, accessory dimensional verification, dual-end sealing performance test and finished-product electrical-performance spot-check. Anti-static packaging protects precision tin-plated female contacts from static discharge and surface contamination in logistics. Material statements and test documents can be supplied for project bidding and internal quality archive. This Goodwe-style connector maintains interchangeable mating dimensions with mainstream photovoltaic circular connectors on market, helping customers achieve cost optimization without sacrificing connection reliability.

Benefiting from 12A per-pin current capacity, 6-pin mixed power-signal layout, dual-end IP67 sealing and field-assembly capability, this Goodwe-Style female solder-wire connector is widely applied for power-signal interconnection of photovoltaic inverters, energy-storage power cabinets and outdoor solar control equipment.

3.1 Distributed Photovoltaic Inverter Systems Used as cable-side female connector for Goodwe string inverters, hybrid inverters and photovoltaic monitoring harness.

Solder-wire termination facilitates quick prototype modification and custom-made test harness production. Stable electrical performance ensures repeatable test data during long-time aging operation.

Q1: What IP protection rating can this Goodwe-Style plum-blossom 6-pin female connector achieve?
A: It reaches IP67 rating under correct assembly prerequisites: red waterproof O-ring fitted at mating face, black O-ring and cable-clamping gland sleeve correctly installed for cable-entry sealing, matching male plug fully thread-locked, and cable outer diameter falls within gland clamping range. IP67 provides dust-tight performance and protection against temporary water immersion. This product is NOT intended for permanent underwater submersion. If IP68 deep-water application is required, please contact our technical team for customized solution.

Q2: Are red waterproof O-ring, cable-clamping gland sleeve and black waterproof O-ring included in standard supply?
A: Yes. The complete plastic three-piece kit including red silicone O-ring, plastic cable-clamping gland sleeve and black silicone O-ring are standard supplied accessories together with female plug housing and contact insert. No separate purchasing of sealing parts is needed for standard field assembly.

Q3: Is this solder-wire type or crimp-contact type? Can crimp terminals be assembled?
A: This is solder-wire-termination female receptacle. Contact tails are designed for wire soldering. Standard version does not support crimp terminals. Users shall solder stranded copper wires onto contact tails by soldering iron. If crimp-contact variant is required for large-scale automatic harness production, please consult our sales team for alternative model.

Q4: What wire gauge and cable outer diameter are recommended? What is per-pin rated current?
A: Recommended stranded copper wire gauge: AWG 22-16. Applicable cable outer diameter: 6.0-12.0 mm. Continuous rated current for each single female pin is 12A. Do not exceed rated current in practical application to avoid abnormal heating and circuit risk.

Q5: What risks will happen if three-piece sealing kit is mis-assembled or gland nut is not fully tightened?
A: Missing or mis-placing red O-ring will cause water-leakage at plug-in mating surface. Missing black O-ring or cable-clamping sleeve, or insufficient tightening of rear gland nut will lose cable-entry sealing and strain-relief function. Moisture and dust will invade connector interior, and cable pulling force may break solder joints. For outdoor usage, all three-piece accessories must be installed correctly and gland nut must be fully tightened.

Q6: Does this product contain the matching plum-blossom 6-pin male plug?
A: This product only supplies Goodwe-Style plum-blossom 6-pin female solder-wire connector and full plastic three-piece kit. Corresponding male plug is sold separately. Please inform our sales if you need complete male-female mating sets.
