Accessory type
As a specialized PV wholesaler, we offer high-quality accessories from renowned manufacturers such as Stäubli and Weidmüller as well as certified cable series for safe DC wiring. This product family stands out for its high reliability, secure contact technology, UV- and weather-resistant insulation, and modular usability. Suitable for private rooftop systems as well as commercial ground-mounted and storage installations.
Typical Applications and Benefits
DC cables and connectors link modules, string cables, inverters and battery systems with minimal losses. They reduce installation times, increase system safety through standardized protective solutions, and enable easy expansion through Y-splitters and MC4-compatible components. Durability under UV/weather exposure and standards compliance for commercial projects are especially important.

Technical Features of Cables & Connectors
PV DC cables use highly tear-resistant, halogen-free insulation (e.g., H1Z2Z2-K / EN 50618) for a long service life and resistance to UV, ozone and temperature fluctuations. Cable cross-sections determine voltage drop and efficiency; larger cross-sections reduce losses over long collector cables. Connectors comply with IEC/EN standards, offer low contact resistance and protection ratings for harsh outdoor conditions. Taken together, standardized components ensure reliable energy management, easy maintenance and maximum system availability.
