Cables / System Wiring – DC Solar Cables & System Cables

Our cables and system wiring segment supplies certified cables and pre-assembled cable sets for PV systems and energy storage. This product family stands out for its high conductivity, weather-resistant insulation (H1Z2Z2-K), low losses and long service life. Typical applications range from residential complexes and single-family homes to commercial roofs, storage connections and commercial solar parks.

High-Performance Solar Cables for Safe System Wiring

These cables offer reliable DC current characteristics, UV- and ozone-resistant insulation, and high temperature and aging resistance. They are suitable for string-side wiring, busbars and DC connections to inverters or battery systems. Benefits include reduced line losses, easy processing on-site and compatibility with commonly used connectors and inverters.

Technical Fundamentals and Features

Typical solar cables are single- or multi-stranded with halogen-free, UV-stable H1Z2Z2 insulation. Sizing (cross-section) determines line losses and thermal load capacity; correct selection ensures efficiency and service life. Safety aspects: temperature-resistant materials, flame-retardant classes, mechanical robustness and certified continuity through to the inverter. For energy management and reliability, compatibility with plug systems, correct cross-section and fuse planning, and durable insulation are decisive.
