RV & Marine Solar Setups Provide flexible power solutions for mobile and marine applications where space and power needs vary. Built-In Protection Functions These MC4 cable assemblies are designed with several features to ensure safe and reliable operation in outdoor solar environments. They boast an IP67 protection rating, providing complete dust ingress protection and resistance to temporary water immersion. • The connectors are UV resistant, preventing degradation from prolonged sun exposure. • A positive locking mechanism ensures a secure connection that resists accidental disconnection, enhancing system safety. • Constructed with UL94-V0 flame-retardant materials, they offer an added layer of safety against fire hazards. Common Questions What is the primary use of these 4-to-1 MC4 cable assemblies? They are designed to connect up to four solar panels in parallel, which increases the total current while maintaining the system voltage. This is ideal for expanding solar arrays and optimising power output. Are these connectors compatible with all solar panels? These assemblies are compatible with solar panels featuring standard MC4 connectors. They are not compatible with older MC3 connectors or other non-MC4 types. Always verify your panel's connector type before purchase. Can these connectors be disconnected easily? MC4 connectors feature a positive locking mechanism for secure connections, which typically requires a special MC4 disconnect tool to prevent accidental separation. This is a safety feature to maintain connection integrity. What does the IP67 rating mean for these connectors? An IP67 rating signifies that the connectors are fully dust-tight and protected against temporary immersion in water (up to 1 metre for 30 minutes). This makes them highly suitable for outdoor use in various weather conditions. Installation Notes Ensure correct polarity (+ to + and - to -) when connecting panels in parallel. Always disconnect power from solar panels before making or breaking connections to prevent electrical arcing. Use appropriate MC4 tools for secure connection and disconnection if required. Verify cable cross-sections match your system requirements for optimal performance. Before You Buy Confirm your solar panels use standard MC4 connectors for compatibility. Check the voltage and current ratings of your solar system to ensure these connectors are suitable. Consider the total cable length needed for your installation, as these assemblies have fixed 10cm leads. For safety and compliance, it is generally recommended to use connectors from the same manufacturer within a system. Always verify product specifications and compatibility with your specific solar system components before purchase and installation. Consult a qualified professional for complex installations.
