Sada solárnych predlžovacích káblov InLine 4 mm², čierna/červená, 0,3 m

The InLine solar cable extension set with 4 mm² conductor cross-section and a 0.3 m length provides a short, flexible connection solution for photovoltaic systems and solar equipment. The pair of cables is insulated in black and red to allow clear identification of negative and positive conductors. Designed for extension and routing of low-voltage DC circuits, the set supports installation work where short jumpers or neat cable runs are required between modules, junction boxes and small inverters.

Advantages

The cable pair uses a 4 mm² conductor cross-section that balances current capacity and flexibility for typical small to medium PV arrays and peripheral devices. Black and red insulation simplifies polarity identification during installation and maintenance. The short 0.3 m length reduces excess slack and helps achieve tidy cable management in tight spaces. Insulated conductors are suitable for protected indoor and weather-protected outdoor installations when used according to applicable mounting and sealing practices.

Suitable for

• Extending connections between solar panels and combiner/junction boxes
• Short jumper connections to microinverters, optimizers or charge controllers
• Neat routing in roof-mounted or ground-mounted PV arrays where short link cables are needed
• Temporary wiring during testing, commissioning, or maintenance of photovoltaic systems

Key specifications

• Conductor cross-section: 4 mm²
• Length: 0.3 m
• Insulation colors: black and red for polarity identification
• Cable type: flexible, insulated DC conductor pair suitable for low-voltage solar applications
• Typical use: short extension/jumper in photovoltaic systems

How to use

Measure the required routing distance to confirm the 0.3 m length is adequate. Strip appropriate lengths of insulation and make secure electrical connections using compatible solar connectors, crimp terminals, or screw terminals rated for the conductor size. Observe proper polarity by matching the red cable to the positive terminal and the black cable to the negative terminal. Ensure connections are tightened to the torque specified by the mating equipment and protected from moisture and mechanical strain using seals, heat-shrink tubing, or approved junction enclosures.

Recommendations

Use the cable set only within the voltage and current limits of the overall PV installation and following local electrical codes. For outdoor exposed installations, complement the set with suitable weatherproofing and strain relief; if permanent outdoor exposure is required, verify UV and temperature ratings of the installed assembly. When in doubt, involve a qualified installer to ensure safe and code-compliant connections.
