## Summary description

QOLTEC Solar Cable 53850 is a 4 mm² cross-section, 100 m long red cable designed for photovoltaic and solar power installations. It provides a consistent conductor size for DC connections between panels, inverters and junctions. Suitable for outdoor solar use where matching polarity and reliable conductor capacity are required; supports easier routing and installation.

## Long description

QOLTEC Solar Cable 4 mm², 100 m, red is a single-core PV cable intended for DC connections in photovoltaic systems. With a 4 mm² conductor cross-section and 100-metre reel length, the cable is designed to connect solar panels, combiner boxes, inverters and junctions while maintaining consistent conductor capacity and clear polarity identification. The red insulation helps distinguish the positive conductor in multi-string arrays and simplifies routing during installation.
Advantages
The cable offers a stable conductor area of 4 mm² suitable for moderate current runs in small to medium photovoltaic installations. Durable insulation provides protection against UV exposure and outdoor conditions typical for rooftop and ground-mounted arrays. The 100 m length on a single reel reduces the need for frequent joins and splices, allowing longer continuous runs and clearer cable management. The red colour insulation supports easy polarity identification and safer assembly of DC circuits.
Suitable for
Interconnecting solar panels in series or parallel strings
DC runs between arrays, combiner boxes and inverters
Small to medium rooftop and ground-mounted photovoltaic installations
Applications where clear polarity marking and uniform conductor size are required
Key specifications
Conductor cross-section: 4 mm²
Length: 100 m
Insulation colour: red
Core type: single-core (solid or stranded conductor appropriate for PV cabling)
Suitable for outdoor solar use with UV-resistant insulation
Designed for DC photovoltaic circuits
How to use
Plan cable runs to minimise voltage drop and avoid unnecessary junctions; measure required lengths and cut from the reel preserving insulation integrity. Strip the insulation at connection points to expose the conductor, taking care not to nick strands. Use appropriately rated connectors, lugs or MC4-compatible terminals for DC PV connections and tighten terminations to manufacturer torque specifications. Route and secure the cable with UV-resistant clips or cable ties, keeping conductors separated by polarity and protected from sharp edges or excessive heat. When joining cables, use approved connection methods and weatherproof enclosures for outdoor terminations.
Usage recommendations
Verify system current and maximum permissible voltage drop for the installation and confirm that 4 mm² conductor size meets the design requirements. Use the red cable for positive DC runs to maintain consistent polarity identification, and follow local electrical codes and installer guidelines for outdoor solar cabling, connectors and protection measures.
