The generous cross-section ensures that the voltage drop is minimised and the overall yield of your system is maximised, even with the high currents of modern high-performance modules.Highlights at a glanceMaximum efficiency: The cross-section of 6mm² massively reduces the electrical resistance and ensures minimal voltage drop, especially over distances of 50 metres.Certified safety: Complies with the IEC 62930 standard (H1Z2Z2-K) for permanent use in photovoltaic direct current systems up to 1500V.Optimum project length: 50 metres in one piece enable uninterrupted installation without additional plug connections between the module array and inverter.Weather & UV resistant: The high-quality XLPO double insulation protects the cable against embrittlement caused by sun, ozone and extreme weather conditions for decades.Corrosion-protected conductor: Fine-stranded, tinned copper offers the best long-term conductivity and provides effective protection against oxidation, even in damp or salty environments.High thermal load capacity: Reliable operation in a wide temperature range from -40°C to +90°C.Areas of applicationThe SOLR650 is the ideal choice for demanding installation scenarios:Large roof systemsPerfect for connecting the solar modules to the inverter if it is installed in the basement or in a remote technical room.Powerful balcony power stationsIdeal for systems with modern modules (500Wp+) to transport the high currents safely and without losses.Island & battery storageIdeally suited for 24V or 48V systems where low voltage drops are crucial for optimum battery charging.Assembly & safety instructionsProfessional connectionOnly use high-quality MC4 connectors that are approved for 6mm² cross-sections. Precise crimping with a special solar crimping tool is essential.Mechanical fixationFasten the cable at regular intervals with UV-resistant cable ties to avoid mechanical stress caused by wind or dead weight on the connections.Avoidance of induction loopsRun positive (red) and negative (black) cables as parallel and close together as possible to minimise electromagnetic interference fields. Features Model / SKU**SOLR650** Conductor cross-section**6.0 mm²** Delivery form**50 metre ring** ColourRed (positive pole) Rated voltageDC: 1.5 kV / Max. 1.8 kV Conductor materialCopper, tinned (class 5) Temperature range-40°C to +120°C (on the conductor) Certification**IEC 62930 / EN 50618** Special featureHalogen-free, UV-resistant & short-circuit-proof  FAQs about solar cable red 50m 6mm²Why is 6mm² for 50 metres better than 4mm²?Due to the lower resistance. The electrical resistance adds up over a distance of 50 metres. With 6mm² you reduce the voltage drop by around a third compared to 4mm². This ensures a higher system voltage at the inverter and therefore a measurably higher yield.Can the cable be laid freely outdoors?Yes. The cable is specially certified for permanent outdoor installation. It is resistant to UV light, ozone and ammonia, which also qualifies it for use in agriculture.Is the cable flame-retardant?Yes. The XLPO insulation is flame-retardant and halogen-free. In the event of a fire, the cable produces hardly any smoke and no corrosive gases, which significantly increases safety in the building.
