Shirbly Solar Panel Wire 10AWG 200FT - Black Tinned-Copper, Weatherproof PV Extension Cable

Shirbly 10AWG 200FT solar panel wire is a weatherproof, tinned-copper PV extension cable designed for outdoor solar, marine, RV and automotive DC systems.

This heavy-gauge 10AWG (6mm²) cable combines 78 fine tinned copper strands with a durable PVC jacket to deliver low-resistance power transfer and long-term protection against UV, moisture and chemicals. Rated to 1500 V and built to tolerate extreme temperatures from -40°F to 248°F (-40°C to 120°C), it’s engineered for applications where reliability and flexibility matter—such as extending panel arrays, wiring batteries and connecting inverters on boats, RVs and off-grid setups.

How does this cable perform in harsh outdoor conditions?

The Shirbly wire uses a UV-stable PVC insulation and tinned copper conductors that resist corrosion and retain flexibility in cold climates. Its wide operating temperature range and moisture resistance make it suitable for rooftop, marine and exposed installations without rapid degradation.

• PVC jacket resists UV, moisture and chemicals.
• Temperature rating: -40°F to 248°F (-40°C to 120°C).
• Tinned copper strands reduce corrosion in salty or humid environments.
• Rated voltage up to 1500 V for solar system compatibility.

Can I use this wire for marine, RV and automotive projects?

Yes—the cable’s tinned copper core and flexible construction make it appropriate for boats, RVs and vehicle-mounted solar setups. The tinning process improves solderability and corrosion resistance, which is important where moisture or salt exposure is likely.

• Flexible 78-strand conductor eases routing around tight bends.
• Easy to strip, solder and terminate for common connectors and busbars.
• Works with DC circuits, inverters, battery banks and LED runs.
• Black jacket blends with most installations for a neat appearance.

What electrical and physical specs should I expect?

This product is 10AWG (6mm²) with 78 strands of 0.295 mm tinned copper, overmolded with a PVC sheath that prioritizes durability. The combination yields lower resistance than many aluminum or smaller-gauge options while staying flexible enough for on-site handling.

• Conductor: 78 strands, 0.295 mm each, tinned copper.
• Cross-sectional area: 6 mm² (10AWG equivalent).
• Length: 200 feet (black jacket).
• Voltage rating: 1500 V suitable for many PV arrays.

How easy is it to install and terminate?

The Shirbly PV wire is designed for straightforward installation—its flexibility simplifies routing and its solder-friendly tinning reduces fraying during termination. Whether you’re crimping lugs, soldering, or using MC4-compatible connectors, the cable behaves predictably and reliably.

• Flexible strands make bending and securing easier.
• Easy to strip cleanly without excessive fraying.
• Solder-friendly tinned copper for reliable joints.
• Compatible with common solar connectors and terminal blocks.

Who is this for? Installers, DIY solar enthusiasts, boat owners and RVers who need a resilient, low-resistance power cable for outdoor DC applications will find this Shirbly 10AWG 200FT PV wire useful. It’s aimed at projects requiring a long run of robust, weather-resistant cable—especially where corrosion resistance and flexible handling are priorities.
