Conjunto de cabo de extensão solar InLine 4 mm² preto/vermelho, 0,75 m

InLine solar cable extension set with 4 mm² conductors in black and red, length 0.75 m is designed to extend and link DC connections in photovoltaic systems. The set provides two flexible insulated conductors with clear polarity marking to simplify wiring between solar panels, inverters and battery systems. Its compact length and standardized conductor size make it suitable for short extensions, branch connections and maintenance work in small to medium PV installations.

Advantages

The cable set offers durable insulation and flexible copper conductors that allow easier routing in confined spaces. Colour-coded black and red conductors reduce wiring errors and speed up installation. With a 4 mm² cross-section the cables support common DC currents in residential and small commercial PV systems while maintaining low voltage drop for short runs. The 0.75 m length provides a tidy, factory-like connection when extending strings or connecting adjacent modules.

Suitable for

• Extending DC connections between solar panels
• Connecting panels to string combiners or inverters over short distances
• Linking battery terminals in off-grid or hybrid systems
• Temporary or permanent maintenance and testing connections

Key specifications

• Conductor cross-section: 4 mm²
• Length: 0.75 m
• Conductor colours: black and red for polarity identification
• Conductor type: flexible, multi-strand copper
• Insulation: weather-resistant flexible PVC or equivalent suitable for outdoor DC use
• Intended use: DC photovoltaic systems and related low-voltage solar applications

How to use

Route the cable avoiding sharp edges and heat sources, then strip appropriate lengths of insulation at connection points. Match the red and black conductors to positive and negative terminals respectively and secure connections using compatible terminals or clamps. Ensure proper torque on terminal screws and verify polarity before energising the circuit. Confirm that the total run length and cumulative connections remain within acceptable voltage drop and current-carrying capacity for the system.

Recommendations

For outdoor installations, protect connections with suitable UV-resistant junction boxes or heat-shrink tubing and check that all terminations meet local electrical codes. Use the cable for short runs or between adjacent modules; for longer distances choose larger conductor cross-sections to reduce voltage drop. Regularly inspect insulation and connections during scheduled system maintenance.
