20A 3 Pin Power Connector M19 DC Waterproof Quick Connector
Product Overview
The M19 3Pin 20A high-current solar connector is a professional DC power connection component customized for photovoltaic power supply systems. Featured with a dedicated 3-pin pure DC power structure, it focuses on high-power transmission demands of solar panels and outdoor energy storage equipment. Equipped with a thread-free Quick Lock self-locking structure, it supports tool-free fast plug-and-lock connection. With IP67 all-weather waterproof grade and excellent outdoor aging resistance, it is professionally optimized for long-term sun exposure, rain erosion and drastic temperature changes, serving as a reliable and low-loss power connection solution for outdoor solar and DC power systems.
Wiring range Assembled: 6.0mm~16mm; Molding 6.0mm~16.5mm
Durability: 3000 times
Applicable temperature: -40℃~105℃
Quick Description
20A High-Current DC Stable Transmission: Optimized for photovoltaic DC power supply characteristics, the connector adopts thickened high-purity copper terminals with ultra-low conduction resistance. It maintains stable 20A continuous DC output with low temperature rise and minimal power loss under full load. It effectively supports long-term high-power operation of solar modules and outdoor energy storage devices without voltage fluctuation or overload failure.
Simplified 3-Pin Pure Power Architecture: The streamlined 3-core pure power layout eliminates redundant signal pin interference, ensuring purer and safer DC circuit transmission. It avoids circuit disorder and poor contact risks common in photovoltaic systems, perfectly matching the non-stop working mode of outdoor solar power supply equipment and improving overall electrical safety.
Tool-Free Quick Lock Self-Locking Design: The upgraded elastic buckle structure enables one-step insertion locking and simple press release. No tools or thread twisting are required, greatly simplifying installation and maintenance for high-altitude and field solar projects. The stable locking tension provides excellent anti-loosening performance against equipment vibration and cable pulling.
IP67 Full Ingress Protection for Outdoor Solar Scenarios: Built with integrated high-elastic sealing gaskets, the connector achieves gapless sealing after locking. It fully resists rainwater soaking, dust accumulation, dew and moisture corrosion, ensuring stable circuit connection in open-air photovoltaic power stations, roof solar systems and outdoor energy storage equipment all year round.
UV-Resistant & Anti-Aging Industrial Housing: Adopting weather-resistant flame-retardant material exclusive for solar equipment, the housing withstands long-term outdoor UV radiation and extreme temperature cycles. It avoids yellowing, cracking and structural deformation, maintaining stable insulation and mechanical performance for prolonged outdoor service life.
Large-Caliber M19 Structure for Heavy-Duty Wiring: The widened M19 cavity structure accommodates large-gauge solar dedicated cables without extrusion or damage. With stronger structural bearing capacity, it perfectly fits high-power photovoltaic circuits and solves the limitations of small-size connectors with insufficient load and narrow wiring space.

Frequently Asked Questions
What is rated voltage?
Rated voltage also known as operating voltage, which mainly depend on the connector insulation material used, the spacing between the size of contact. Some of the components or devices in less than its rated voltage may not be completed to its functions.
How many materials you can provide?
There's some different materials from connector and cable, we usually use PVC/Nylon material to product connector, PVC/Rubber/Silicone material was used in cable. Of course we can also according to your requirments to choose the material.
Can I have custom label?
Yes,of course,you can make you own private label and package,if you need to design the packaging ,we also have professionaldesigner to serve you.
