Why Cables & Connections Matter

Making The Right Connections

MC4s: These German-engineered MC4 connectors are IP67-rated, UV-resistant, and EN50521-compliant to ensure your solar system runs at peak efficiency.

Solar Cable: Incorporating the right solar panel cable and solar panel extension cable is crucial for your solar installation to stay protected and function well. Choose cables with features like UV and corrosion resistance, insulation, connector compatibility and more.

Frequently Asked Questions

MC4 solar connectors are specialised electrical connectors used in solar power systems to connect solar panels to charge controllers, batteries, and inverters. They consist of two parts: the MC4 male connector (plug) and the MC4 female connector (socket), which ensure secure and efficient connections in solar arrays.

MC4 solar connectors are essential for safely and efficiently wiring a solar array. They simplify the installation process by making connections faster and less complicated. With their proven MULTILAM technology, MC4 connectors provide high long-term stability, reduce the risk of overheating, and ensure minimal performance loss throughout the lifespan of the connector.

Staubli MC4 connectors are certified to EN50521 โ€“ the European standard for photovoltaic connectors โ€“ ensuring that they meet rigorous safety and performance requirements. Additionally, they are UV-resistant and IP67-certified for dust and water resistance. This makes them ideal for use in harsh outdoor environments.

While MC4 connectors are designed for easy assembly with minimal tools, proper crimping and installation are essential to ensure a secure connection. We even have an instructional video on MC4 crimping here.

DC Cables: Solar panel systems generally use direct current (DC) to generate electricity. For this reason, our solar cables are DC cables to minimise losses and transfer energy from your solar panels more efficiently to your system components.
UV Resistance: Solar panel cables are typically made to be UV-resistant because they are exposed to constant sunlight. This characteristic ensures the cables donโ€™t degrade under prolonged sun exposure, maintaining their integrity and functionality over time.
Insulation Properties: Good insulation is essential in solar cables to prevent electrical leaks and short circuits. This not only protects the sensitive circuits and units within the solar system, but also enhances the safety of the entire installation.
Suitability for Different Environments: Solar cables are designed to withstand various environmental conditions, from extreme heat to cold, ensuring reliable performance irrespective of the installationโ€™s location.
Durability: These cables are built to endure physical stresses like bending and twisting, which is crucial for complex routing installations.
High Current Carrying Capacity: Solar panel cables are designed to handle the high current typical in solar power systems, ensuring efficient energy transfer without overheating or energy loss.
Flexibility and Ease of Installation: The flexibility of solar panel extension cables makes them easy to install, especially in systems with complex layouts or limited space.
Corrosion Resistance: Solar cables are often corrosion-resistant, an important feature considering the outdoor placement and exposure to various elements.
Compatibility with Connectors: These cables are specifically designed to be compatible with standard solar connectors, facilitating secure and efficient connections within the system.
Choosing the right size for your solar cables can significantly impact the efficiency of your system. We offer both 4mm and 6mm robust solar cables that are purpose-built for longevity and can accommodate different needs.
MC4 connectors are compatible with 4mm, 6mm and 10mm solar cables. They are designed to provide a secure and efficient connection for both residential and commercial solar systems, ensuring optimal performance with minimal energy loss.
Our solar cables are available in various drum sizes to suit different solar projects. This allows you to select the most cost-effective and suitable size for your specific needs, minimising waste and maximising value. Key factors to consider include the following:
  • Current carrying capacity
  • Installation size
  • Cable run length
  • Environmental conditions
The 4mm solar cable has a thinner diameter, making it easier to handle and install in tight spaces. It is typically suitable for smaller installations or shorter distances with lower current loads.
The 6mm solar cable ideal is thicker in diameter and can handle higher current loads, making it suitable for larger installations, longer cable runs, and systems with stronger energy requirements. It also has better resistance to physical and environmental stressors. This ensures efficiency and safety in more demanding solar setups.
