Solar cable QOLTEC 53852 6 mm², 100 m roll, red

Single-core solar cable QOLTEC 53852 with 6 mm² conductor cross-section on a 100 m roll in red is designed for DC connections in photovoltaic and solar power systems. The cable is intended for interconnecting solar panels, routing power to inverters and batteries, and creating reliable feed lines within the array. Its red outer sheath provides clear polarity identification and aids organized cable runs during installation.

Advantages

This solar cable offers stable current-carrying capacity for typical small to medium PV strings and energy storage connections. The single-core, solid-conductor design ensures consistent electrical performance over the roll length, while the red insulation simplifies identification of positive DC conductors. The construction is suitable for outdoor routing when installed with appropriate conduit or protective trunking, allowing long continuous lengths without frequent splices.

Suitable for

• Interconnection of solar panels in series or parallel within PV arrays
• DC cable runs from arrays to inverters and charge controllers
• Connections between batteries and solar charge systems
• Temporary or permanent installations where single-core outdoor-rated cable is required

Key specifications

• Conductor cross-section: 6 mm²
• Conductor type: single-core (solid) copper conductor
• Length: 100 m roll
• Insulation colour: red (positive polarity marking)
• Application: DC photovoltaic and solar power installations
• Suitable for outdoor routing when protected from mechanical damage

How to use

Strip the insulation to the required length and terminate the conductor with compatible solar-rated connectors, lugs or clamp terminals following manufacturer torque specifications. Route the cable along protected trays, conduits or cable ties to avoid UV and mechanical damage, and maintain correct polarity by using the red conductor for positive DC connections. Ensure all connections are tight, properly insulated and weatherproofed where exposed, and observe local electrical codes and safety practices during installation.

Recommendations

For long runs and higher-current systems, verify voltage drop and thermal loading to confirm 6 mm² is suitable. Protect the cable from direct mechanical impact, use UV-resistant conduit or trunking for prolonged sun exposure, and avoid placing the conductor near sources of excessive heat. When connecting to battery systems or inverters, follow the device manufacturer’s guidance for terminal preparation and torque values.
