4mm² Twin Solar Cable – PV1-F 1000V – 100m Roll

Professional-Grade Twin-Core Solar Cable for Demanding PV Installations

The 4mm² Twin PV1-F Solar Cable on a 100-metre roll is engineered for installers and system integrators who require a durable, high-performance wiring solution for photovoltaic systems. With a 1000V DC rating, this twin-core cable is suitable for medium to large-scale solar arrays, including residential, commercial, and off-grid applications. Its fine-stranded tinned copper conductors and cross-linked insulation ensure reliable power transmission and long-term resilience in harsh Australian environments.

Unlike standard building wire, this PV1-F solar cable is specifically designed for the unique demands of solar installations. It offers superior resistance to UV radiation, ozone, and temperature extremes, reducing the risk of insulation degradation and system faults over time. The twin-core figure-8 configuration simplifies cable management by keeping positive and negative conductors together, which can lower installation time and reduce the chance of wiring errors.

Key Features

• 1000V DC rating for compatibility with modern high-voltage solar arrays
• Tinned copper conductors provide excellent corrosion resistance and conductivity
• Cross-linked insulation and sheath for enhanced thermal stability and mechanical protection
• UV and weather resistant – suitable for exposed outdoor installations without additional conduit
• Flame retardant construction adds an extra layer of safety in fault conditions
• Flexible design eases routing through conduits, cable trays, and tight spaces
• 100-metre roll provides ample length for large projects or multiple smaller installations

Built for Australian Conditions

Australia’s intense sun, coastal salt spray, and temperature swings can degrade inferior cables quickly. This PV1-F solar cable is manufactured with a cross-linked polyolefin insulation and sheath that maintains its integrity from -40°C to 90°C under normal operation, with a maximum conductor temperature of 120°C. The tinned copper conductors resist oxidation, ensuring low-resistance connections even after years of service. These properties make it a reliable choice for caravan solar panels, marine solar systems, and remote off-grid installations where failure is not an option.

Optimised for System Performance

Voltage drop is a critical factor in solar system efficiency. The 4mm² conductor size offers a practical balance between current-carrying capacity and flexibility, making it a popular choice for string wiring and home-run connections in arrays up to several kilowatts. With a conductor resistance of approximately 5.09 Ω/km at 20°C, this cable helps minimise power losses over typical installation distances. *Note: Maximum current rating is installation-dependent; typical de-rating factors apply based on ambient temperature, conduit fill, and grouping.

Applications

This twin solar cable is ideal for connecting solar panels to combiner boxes, charge controllers, and inverters in a wide range of settings:

• Residential and commercial rooftop solar arrays
• Off-grid and stand-alone power systems
• Caravan, RV, and camper trailer solar upgrades
• Marine and coastal solar installations
• Solar water pumping and remote monitoring stations

Professional Installation Ready

Supplied on a 100-metre roll, this cable allows installers to cut precise lengths on site, reducing waste and ensuring a tidy installation. The twin-core format eliminates the need to run separate positive and negative cables, speeding up the wiring process and improving aesthetics. The cable is marked with “CAUTION DC CABLE – DO NOT DISCONNECT UNDER LOAD” for compliance and safety awareness.
