Red solar cable 100 m 4 mm²

The SOLR4100 solar cable (100 metres, 4 mm²) ‘in Rot’ is the ideal cable sold by the metre for large-scale photovoltaic projects and professional installations. With a generous length of 100 metres per roll, it offers maximum flexibility when cabling roof-mounted systems, ground-mounted projects or larger stand-alone systems. The red marking clearly identifies the positive terminal (+), which significantly enhances safety and clarity during installation.

The cable has been specially developed to meet the extreme demands of outdoor use. Thanks to its high-quality 4 mm² cross-section and special double insulation, it is ideally equipped to safely transmit the energy generated by your solar panels with minimal loss for decades to come.

Key features at a glance

• Long range: 100-metre lengths allow for custom cutting without unnecessary intermediate connections or waste.
• Clear polarity: The red outer sheath clearly identifies the positive lead and prevents errors during installation.
• Robust double insulation: The cable features a flame-retardant and halogen-free sheath, which offers optimum protection against mechanical stress.
• Weatherproof & extremely durable: Specially developed for long-term outdoor use – UV-resistant, ozone-resistant and resistant to acids and alkalis.
• Wide temperature range: Reliable operation in extreme weather conditions from -40°C to +90°C (maximum conductor temperature up to +120°C).
• Optimal conductivity: The fine-stranded tinned copper conductor ensures consistently low contact resistance and provides effective protection against corrosion.

Areas of application

The SOLR4100 is the first choice for a wide range of installation scenarios:

• Roof-mounted systems & solar farms
  • Creation of customised string connections from the module array to the inverter or junction box.
• Off-grid systems & motorhomes
  • Flexible cabling for off-grid systems, where precisely tailored cable lengths are required for a neat installation.
• Plant engineering
  • An ideal basic component for installers for assembling customised connection cables with MC4 connectors.

Installation & Safety Instructions

• Professional assembly
  • As this is sold by the metre without connectors, we recommend using high-quality MC4 connectors and professional crimping pliers designed for solar cables for the connection.
• Protection against rodents
  • When laying the cable in areas at risk from rodents (e.g. barns or on the ground), it should also be routed through a suitable protective conduit.
• Installation in accordance with standards
  • Ensure that the cable is laid without tension and secured with UV-resistant cable ties to prevent chafing caused by wind.

FAQs on the red 100m 4mm² solar cable

Is the cable suitable for direct burial?

To a limited extent. The cable is suitable for laying in pipes and ducts in the ground, provided that it is not permanently submerged in water. Direct burial in the ground without a protective conduit is not recommended.

Can I also use this cable for 1500V systems?

Yes. As an H1Z2Z2-K-certified cable, it is designed for a maximum system voltage of 1500V DC and thus complies with the latest standards for photovoltaic installations.

Why is the conductor tinned?
