4mm PV Solar cable

A 4mm² PV (Photovoltaic) Solar Cable is a specialized electrical cable designed specifically for use in solar power systems. It connects solar panels to inverters or charge controllers and is built to withstand harsh environmental conditions over long periods.

Key Specifications

• Conductor Size:

  • 4mm² cross-sectional area (approximately equivalent to AWG 11)

• Conductor Material:

  • Tinned copper (for corrosion resistance) or bare copper

• Insulation & Sheath:

  • Electron-beam cross-linked XLPE (typically designated as XLPO or similar)

  • UV-resistant and weatherproof

• Voltage Rating:

  • 600/1000V AC

  • Up to 1500V DC (depending on standards compliance)

• Temperature Range:

  • Operating: -40°C to +90°C

  • Short-circuit tolerance: up to 120°C

• Outer Diameter:

  • Approximately 5.5mm to 7mm (may vary slightly by brand)

• Standards Compliance:

  • TÜV 2PfG 1169/08.2007 or EN 50618 (for newer installations)

  • RoHS compliant

Key Features

• UV and Ozone Resistant:
  Built to last outdoors for over 25 years without degradation.

• Halogen-Free:
  Produces less toxic smoke in the event of a fire.

• Double Insulated:
  Provides added safety and durability in solar installations.

• High Flexibility:
  Suitable for fixed installations and easy routing in complex setups.

• Weather and Abrasion Resistant:
  Performs reliably in extreme conditions including direct sunlight, rain, and snow.

Typical Applications

• Connecting solar panels to combiner boxes

• Wiring from combiner boxes to inverters

• Used in rooftop, ground-mounted, or mobile PV systems

 Lengths & Colors

• Common lengths: Sold by the meter, in 50m, 100m, or 500m rolls.

• Common colors: Black (for negative) and Red (for positive)
