InLine 95455 Solar Extension Cable Set, 4 mm², Black/Red, 0.5 m

InLine Solar Cable Extension Set 95455 is a paired 0.5 m solar extension cable with a 4 mm² conductor cross-section in black and red. Intended for use with photovoltaic modules, charge controllers and inverters, the cable set provides clear polarity identification and reliable current carrying capacity for small to medium solar installations. The short length and flexible jacket make it suitable for tidy routing and quick, secure connections inside junction boxes, combiner boxes or at module terminals.

Advantages

The paired black and red conductors ensure unambiguous polarity identification during installation and maintenance. A 4 mm² conductor cross-section supports stable power transmission for lower-voltage solar arrays and reduces voltage drop over the short extension length. The cable jacket is designed for indoor and outdoor use, offering mechanical flexibility for routing in confined spaces while maintaining electrical insulation and protection against common environmental factors encountered in residential and small commercial PV systems.

Suitable for

• Short solar module-to-module extensions
• Connecting modules to charge controllers or inverters in small PV systems
• Neat routing inside junction or combiner boxes
• Temporary or permanent short-span photovoltaic wiring

Key specifications

• Conductor cross-section: 4 mm²
• Length: 0.5 m (paired cable)
• Color coding: black and red for negative and positive identification
• Suitable for indoor and outdoor installation
• Flexible insulated jacket for easy routing

How to use

Strip an appropriate length of insulation from the conductor ends, taking care not to nick the copper strands. Make secure connections using compatible solar connectors, screw terminals or properly rated crimp terminals, ensuring correct polarity alignment of the red (positive) and black (negative) conductors. Route the cable to avoid sharp edges and excessive bending radii; fix in place with suitable clamps or cable ties. Verify electrical continuity and polarity before energizing the circuit and follow applicable local electrical codes and safety practices during installation.

Recommendations

Use this short extension set where minimal additional cable length is required and where clear polarity marking is important. For longer runs or higher current demands, select a larger conductor cross-section and appropriate cable type to minimize voltage drop and meet system requirements.
