6mm² Twin Solar Cable – IEC 62930 1500V – Per Metre

Professional-Grade Solar Cable for Caravans, RVs, and Off-Grid Systems

Engineered for demanding solar installations, this 6mm² twin solar cable delivers reliable power transfer in 12V, 24V, and 48V solar systems. With a maximum DC voltage rating of 1500V, it exceeds the requirements of most residential and mobile setups, providing headroom for larger arrays and future expansion. The tinned copper conductors resist corrosion, ensuring low resistance and consistent performance over time—critical for installations exposed to moisture or coastal air.

Sold per metre and cut to your specified length (up to 100m continuous), this cable reduces waste and allows precise budgeting for projects of any scale. The twin-core design keeps positive and negative conductors neatly paired, simplifying cable management and reducing installation time in tight spaces like caravan roofs or engine bays.

Built to IEC 62930: Safety and Longevity in Harsh Conditions

Compliance with IEC 62930 means this cable meets stringent international standards for solar PV applications. The cross-linked polyethylene (XLPE) insulation and jacket provide excellent resistance to UV radiation, heat, and abrasion—common challenges in the Australian environment. Unlike standard PVC cables, XLPE maintains flexibility and dielectric strength across a wide temperature range (-40°C to +90°C), reducing the risk of insulation cracking or failure over decades of service.

The cable's flame-retardant properties (IEC 60332-1-2) add an extra layer of safety, minimising fire propagation risk in the event of a fault. For installers, the dynamic bending radius of 8x outer diameter allows routing around obstacles without compromising conductor integrity.

Optimised Current Capacity for Medium to High-Power Systems

With a maximum current rating of 70A at 20°C, this 6mm² cable supports substantial power flows, making it suitable for connecting solar panels to charge controllers, battery banks, and inverters. The low DC resistance (≤3.39 Ω/km) minimises voltage drop, preserving system efficiency—especially important in low-voltage 12V setups where even small losses can impact charging performance. *Note: typical de-rating factors apply for elevated temperatures, bundling, or enclosed conduits.

Key Features

• Tinned copper conductors for superior corrosion resistance and long-term low resistance
• XLPE insulation and jacket rated for 1500V DC and 1000V AC
• UV and weather resistant for outdoor use in harsh Australian conditions
• Flame retardant to IEC 60332-1-2 for enhanced safety
• Twin-core configuration simplifies wiring and reduces clutter
• Wide temperature range (-40°C to +90°C) for reliable operation in extreme climates
• Flexible yet robust with dynamic bend radius of 8x OD

Applications Beyond the Basics

While ideal for caravan solar panels and RV solar wiring, this cable excels in any off-grid or grid-tied PV system requiring durable, high-voltage DC connections. Use it for:

• Interconnecting solar panels in series or parallel
• Linking combiner boxes to charge controllers
• Battery-to-inverter cabling in 12V, 24V, or 48V banks
• Marine and coastal installations where salt spray is a concern
• Remote industrial monitoring and telemetry systems

By choosing a cable that meets IEC 62930 and RoHS standards, you reduce the risk of premature failure, voltage drop issues, and safety hazards often associated with lower-grade alternatives. This translates to fewer maintenance visits and greater peace of mind for your energy system.
