WindyNation 10 AWG Solar Extension Cable Pair 50 ft Red + 50 ft Black — UL4703, IP67 PV Connectors

WindyNation’s 10 AWG PV extension cable pair (50 ft red + 50 ft black) is a UL4703-rated, 600V solar cable set terminated with one male and one female weatherproof PV connector for reliable photovoltaic connections.

These pre-terminated solar extension cables are built for outdoor PV systems that need durable, low-resistance wiring. Each 50-foot run gives you flexible routing options between panels, combiner boxes, and inverters while meeting National Electric Code requirements for photovoltaic module interconnection. The combination of pure copper conductors, XLPE jacket, and IP67-rated connectors keeps performance steady in sun, rain, and temperature extremes.

How does this cable support efficient solar output?

The 10 AWG conductors use pure copper with tightly stranded wire to minimize resistance and voltage drop across longer runs. Lower resistance preserves more of the panel’s generated current before it reaches your charge controller or inverter. The PV-rated construction is intended specifically for the electrical and environmental demands of solar arrays.

• 105 tinned copper strands in each 10 AWG conductor for high conductivity and flexibility
• Rated 40A for 10 AWG to match typical string currents
• 600V UL4703 photovoltaic rating to reduce power loss and ensure safe operation

Are the connectors and cable durable for outdoor installations?

Yes — both the XLPE insulated cable and the rugged PV connectors are designed to resist UV, abrasion, heat, cold, and moisture. The connectors are IP67-rated, sealing out dust and withstanding temporary immersion, while the cable jacket tolerates direct burial and wide temperature swings without cracking or stiffening.

• XLPE jacket resists UV, abrasion, and temperature extremes (-40°C to 90°C)
• IP67-rated male and female PV connectors for waterproof, weatherproof coupling
• Constructed for direct burial or exposed outdoor routing

Will these cables comply with electrical codes and installation needs?

The WindyNation extension pair is manufactured to meet NEC wiring rules for photovoltaic systems and comes UL4703-approved, making them suitable for use with or without raceway per Article 690 of the National Electric Code. Pre-terminated connectors simplify installation and reduce field termination errors.

• UL4703 approval for photovoltaic use and NEC Article 690 compliance
• One male and one female PV connector per cable, compatible with industry-standard PV connectors
• Assembled and quality-checked in California with pneumatic crimping to ensure secure terminations

How do I use these 50 ft cables in a typical system layout?

The paired 50 ft red and black cables provide polarity-identified runs for linking panel strings, extending distance to combiner boxes, or routing to charge controllers or inverters. Their length and flexibility free you to plan array layout without many intermediate junctions, reducing points of failure.

• Use red as positive and black as negative to maintain clear polarity
• Ideal for panel-to-panel, panel-to-combiner box, or panel-to-controller extensions
• Pre-terminated connectors accelerate on-site hookup and reduce labor time

Who is this for? Installers, contractors, and DIY solar owners who need a reliable, code-compliant extension solution will benefit from WindyNation’s 10 AWG 50 ft pair. It’s suited to small- to medium-sized arrays where low voltage drop, weather resistance, and quick field hookups matter. Choose this set when you want factory-terminated PV wiring built for outdoor longevity and predictable electrical performance.
