InLine sada solárnych predlžovacích káblov 4 mm², čierna/červená, 1,5 m – PV predlžovací kábel

InLine solar cable extension set 4 mm², black/red, 1.5 m – solar PV extension provides a short, flexible connection solution for photovoltaic arrays. The set contains a matched pair of insulated conductors in black and red with a 4 mm² cross-section and a total length of 1.5 m, intended to extend or bridge close connections between solar panels, module strings and nearby junction points. The clear color coding supports correct polarity identification and helps reduce wiring errors during installation.

Advantages

The 4 mm² conductor cross-section balances current capacity and flexibility for short runs in PV systems. Flexible insulation suitable for outdoor use allows the cables to be routed along panels, frames and mounting structures without excessive strain. The paired black and red conductors simplify polarity recognition and speed up installation checks. Compact length and straightforward design make the set convenient for correcting small layout gaps or providing tidy connections within an array.

Suitable for

• Connecting adjacent solar panels or module strings where a short extension is needed
• Linking panels to local junction boxes or combiner units within a PV array
• Temporary or permanent wiring adjustments on rooftop and ground-mounted systems
• Repairing or replacing short damaged cable runs between modules

Key specifications

• Conductor cross-section: 4 mm²
• Cable length: 1.5 m (pair)
• Color: black and red for polarity identification
• Insulation: flexible, suitable for outdoor PV use
• Designed for low-voltage DC solar PV applications

How to use

Select the black and red conductors according to system polarity, strip insulation to the appropriate length for your connector or terminal, and secure conductors with compatible crimp lugs, MC4-style connectors or screw terminals as required by your installation. Route the cable pair along mounting rails or cable management channels to protect against abrasion and secure with UV-resistant ties or clips. Verify continuity and correct polarity before energizing the circuit, and ensure connections are weatherproofed at exposed junctions.

Recommendations

Use this extension set for short runs only; for longer distances select cabling with appropriate cross-section to limit voltage drop. For permanent outdoor installations, confirm compatibility of end connectors and use approved sealing methods on exposed terminations. Follow the PV system manufacturer and local electrical regulations when integrating these cables into a live array.
