Technical Specifications Parameter Value Cable Length (each) 5 metres Cable Cross-Section 4.0mm² Conductor Material Tinned Copper Insulation Material XLPE (120°C Rated) Connector Type MC4 (Male & Female) Operating Temperature -40°C to +120°C Max Current Rating (approx.) 30A (for 4mm²) Certification TUV Certified Cable Performance & Construction These Photonic Universe solar extension cables are engineered for robust performance and longevity in demanding outdoor environments. The use of tinned copper conductors provides superior electrical conductivity and enhanced corrosion resistance, crucial for long-term reliability in solar installations. The cables feature XLPE (Cross-linked polyethylene) insulation, rated for continuous operation up to 120°C. This high-grade insulation offers excellent resistance to UV radiation, ozone, abrasion, and extreme temperatures, ensuring consistent power delivery and safety throughout the cable's lifespan. Typical Applications Application Description Off-Grid Systems Ideal for powering remote cabins, RVs, boats, or independent setups using 12V solar panels and systems up to 160W. On-Grid Installations Suitable for larger scale grid-tied systems, efficiently managing typical panel voltages of 30-60V and higher power ratings. Residential & Commercial Excellent choice for solar panel arrays in homes, businesses, and diverse industrial environments. Outdoor Solar Power Indispensable for any outdoor solar power installation where durability and consistent performance are paramount. Safety & Durability Features These Photonic Universe solar extension cables are built for reliability and safety. They are TUV certified, ensuring compliance with stringent international safety and performance standards for solar cables. The integrated MC4 connectors are waterproof, providing a robust and sealed connection that is crucial for protection against moisture and environmental ingress in adverse weather conditions. The XLPE insulation also offers excellent UV and ozone resistance, preventing degradation from prolonged sun exposure. Common Questions What is the maximum current these 4.0mm² cables can handle? These 4.0mm² solar extension cables are generally rated to safely handle currents up to approximately 30 Amps, depending on specific installation conditions and ambient temperature. Are these cables suitable for outdoor use? Yes, absolutely. These cables are constructed with UV-resistant XLPE insulation and waterproof MC4 connectors, designed to withstand extreme temperatures from -40°C to +120°C, making them highly suitable for continuous outdoor exposure in the UK climate. Can I connect multiple pairs of these cables together for longer runs? While technically possible to extend cable runs, it's crucial to consider voltage drop and current capacity. Excessive length can lead to significant power loss and reduced system efficiency. Always calculate voltage drop for your specific system requirements before extending cable runs. Consult a qualified installer if unsure. What is the benefit of tinned copper conductors? Tinned copper conductors offer superior corrosion resistance compared to bare copper, especially in humid or marine environments. This enhances the cable's lifespan and maintains optimal electrical conductivity over time, ensuring reliable performance of your solar system. Installation Notes Ensure all connections are clean, dry, and securely fastened to prevent arcing or power loss. Always match the male MC4 connector to a female counterpart and vice-versa for a proper seal. Route cables to avoid sharp bends, excessive tension, or potential damage from foot traffic or wildlife. Use appropriate cable management clips or ties to secure cables and prevent them from dangling. For safety, always disconnect solar panels from the system before making or breaking connections. Before You Buy Verify the required cable length for your specific solar panel placement to minimise voltage drop. Confirm your existing solar panels or charging kits use standard MC4 connectors for compatibility. Check the current and voltage requirements of your solar system to ensure 4.0mm² cable is sufficient. Consider future expansion plans to determine if longer or additional cables might be needed. Consult your system's manual or a qualified electrician if you are unsure about cable sizing or installation. Please verify all specifications and compatibility requirements with your existing solar setup before purchase. Product specifications are based on manufacturer data and industry standards.
