Shirbly 10AWG Tinned Copper PV Extension Cable 50ft Pair — 1500V UV-Resistant Flexible PVC Jacket

Shirbly 10AWG (6mm²) tinned copper PV extension cable is a 50-foot red-and-black pair built for reliable outdoor solar, RV, marine, and automotive DC connections.

This heavy-duty photovoltaic extension set combines flexible tinned copper conductors, a durable PVC jacket, and a 1500V rating to handle long runs and harsh conditions. Designed for solar arrays, battery banks and DC accessories, the cable resists UV, moisture and common chemicals while staying pliable in cold weather. The red and black color-coded pair simplifies polarity identification for panels, controllers and inverters.

How does this cable perform in extreme temperatures and outdoor environments?

The Shirbly PV cable is formulated to tolerate wide temperature swings and outdoor exposure without losing insulation integrity. Its PVC sheath is UV-treated and moisture-resistant, and the conductor remains flexible as cold as -40 °F and stable up to 248 °F (-40 °C to 120 °C). That durability helps reduce cracking, embrittlement and electrical risk over time.

• Temperature range: -40 °F to 248 °F (-40 °C to 120 °C)
• UV- and moisture-resistant PVC outer jacket
• Chemical resistance for marine and industrial atmospheres

What makes the conductor and insulation suitable for solar and DC systems?

The cable uses tinned copper made from 78 strands of 0.295 mm wire, offering a balance of conductivity and flexibility ideal for repeated bending and vibration-prone installations. Tin plating reduces corrosion in salty or humid conditions, extending service life compared with bare copper. The PVC insulation offers an extra safety barrier while meeting the voltage requirements of modern PV systems.

• 78 strands of 0.295 mm tinned copper per conductor for flexibility
• Tinning improves corrosion resistance in marine or coastal use
• Rated for up to 1500 V DC suitable for many solar arrays

How easy is the cable to install and integrate with existing systems?

Shirbly built these 50-foot lengths to simplify layout planning and panel placement, giving installers room to route between modules, charge controllers and battery enclosures. The insulation peels and terminates neatly for soldering, crimping, or lug attachment, while the red/black color pair reduces assembly errors. The wire's flexibility makes it straightforward to fish through conduit, anchor points, or cable trays.

• 50 ft (per conductor pair) for extended panel-to-controller runs
• Easy to strip, solder, crimp, or attach ring/fork terminals
• Color-coded red and black for quick polarity checks

Will this cable work for marine, RV, and automotive installations?

Yes — the combination of tinned copper strands and a robust PVC jacket makes the cable well-suited for vehicles and boats where salt spray, vibration, and tight routing are common. It’s commonly used for panel-to-controller runs, DC accessories, inverters, and LED runs. Always match wire gauge and system voltage to your equipment and local electrical codes.

• Well-suited for RV roofs, marine panels, boats and vehicle-mounted solar
• Resists vibration and corrosive environments thanks to tin plating
• Use with proper connectors and fuse protection per system design

Who is this for: installers, DIY solar homeowners, boat and RV owners, and mobile electricians who need a durable, flexible 10AWG (6mm²) extension cable for DC solar circuits. If you require reliable corrosion resistance, long run capability, and a high-voltage PV rating in a color-coded pair, this Shirbly 50 ft set is built to meet those needs. Confirm gauge, length and voltage compatibility with your equipment before finalizing installation.
