Solar cable Solpar SOLAR1X4 H1Z2Z2-K 1x4 mm² black, 500 m

Solpar SOLAR1X4 H1Z2Z2-K is a solar DC cable with a single 4 mm² conductor and 500 m length in black. It is designed for photovoltaic systems and solar installations to provide a durable DC connection between solar panels, combiner boxes and inverters. The cable's H1Z2Z2-K classification indicates suitability for use in solar arrays where UV and weather-resistant insulation is required for outdoor and rooftop applications.

Advantages

The cable offers a single-core 4 mm² conductor that balances current capacity and ease of handling for many PV string configurations. Its H1Z2Z2-K rating provides enhanced UV and weather resistance compared with standard cables, and the black outer sheath helps with heat absorption and long-term durability in exterior installations. The 500 m drum length reduces the number of joins and simplifies long-run installations.

Suitable for

• Connections between solar panels and string inverters
• DC runs on rooftop and ground-mounted photovoltaic arrays
• Combiner box to inverter DC feeders
• Outdoor solar installations requiring UV- and weather-resistant cable

How to use

Install the Solpar SOLAR1X4 cable following local electrical codes and PV installation standards. Route the cable from the panel strings to combiner boxes and inverters, secure it with appropriate UV-resistant clips or conduits, and avoid sharp bends near terminations. Strip insulation only where required for proper connector or lugs, ensure correct polarity on DC connections, and use suitable crimped or crimp + soldered lugs and weatherproof junctions. Verify system continuity and insulation before energising the PV system.

Recommendations

Store the cable drum upright in a dry, shaded area; protect the sheath from prolonged mechanical abrasion. For long DC runs use correct cross-section and follow manufacturer guidelines for maximum current and temperature ratings. Consult a certified PV installer for systems that require multiple parallel strings or special grounding arrangements.
