Low-loss DC connection for long cable runs in PV systems
This 38-meter cable with MC4 connectors, 6 mm² cross-section, black, is designed for reliable and efficient DC cabling in photovoltaic systems over longer distances. The 6 mm² conductor cross-section significantly reduces voltage drop and is ideal for long string connections between solar modules , string distributors, and inverters . The black insulation is typically used for the negative terminal and ensures clear, standards-compliant cable routing.
Thanks to the pre-installed MC4 connectors on both ends, the cable is ready for immediate use and allows for quick and clean installation without any additional assembly. Its robust design is intended for permanent outdoor use.
