It comes pre-fitted with industry-standard MC4 connectors, which are widely used for quick and secure connections in solar arrays. The cable is rated for medium and low voltage applications up to 35 kV, aligning it with the requirements of many residential and commercial solar installations. Its construction focuses on durability for outdoor use, employing materials chosen for their electrical and safety properties within the context of renewable energy infrastructure.\u003c\/p\u003e\n\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"4 square mm single-core solar PV extension cable with black MC4 connectors on both ends.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/600\/2025-10-02\/original-image\/1617949532820.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThe cable's design centres on practical requirements for solar installations, from its connector type to its material specification.\u003c\/p\u003e\n\u003ch3\u003eMaterial and Build\u003c\/h3\u003e\n\u003cp\u003eThe core conductor is made from tinned copper wire, which provides the necessary electrical conductivity while the tin coating offers an additional layer of protection against oxidation and corrosion, which can be beneficial in outdoor environments. Both the insulation and the outer sheath are constructed from low-smoke, halogen-free material. This type of material is a specified choice for certain cable applications, contributing to the cable's overall construction profile.\u003c\/p\u003e\n\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\n\u003cp\u003eThe cable has a nominal cross-sectional area of 4 square millimetres, a common size for solar PV applications. Its maximum outer diameter can range from 2.5 mm to 6 mm. It is offered in five distinct, fixed lengths to suit different installation layouts: 1 metre, 2 metres, 3 metres, 5 metres, and 10 metres. This allows you to select a length that minimises excess cable while reaching the necessary connection points. The cable is also available in either black or red, enabling basic colour-coding within a system if desired.\u003c\/p\u003e\n\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"4 square mm single-core solar PV extension cable with black MC4 connectors on both ends.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/600\/2025-10-02\/original-image\/1617949532840.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThis product has a clear application within the field of solar energy, serving as a connecting component between key parts of a PV system.\u003c\/p\u003e\n\u003ch3\u003eEvent or Professional Use\u003c\/h3\u003e\n\u003cp\u003eFor professional solar installers or DIY enthusiasts working on renewable energy projects, this cable simplifies the process of extending connections. The pre-attached MC4 connectors mean no additional crimping tools are required for the cable ends, saving time and ensuring a compatible connection interface. Its specification for use up to 35 kV covers the voltage range found in many solar installations, making it a practical choice for extending runs from solar panels to string combiners or inverters.\u003c\/p\u003e\n\u003ch3\u003eEveryday Home Use\u003c\/h3\u003e\n\u003cp\u003eFor homeowners with existing solar panel systems, this cable can serve as a spare or replacement part for extending array strings or making adjustments to the system layout. The fixed lengths allow for a tidy installation without the need for cutting and re-terminating cables. The available colour options can help distinguish between positive and negative lines or different circuit strings during maintenance or troubleshooting, based on common installation practices.\u003c\/p\u003e\n\u003ch2\u003eBenefits and Buying Value\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"4 square mm single-core solar PV extension cable with black MC4 connectors on both ends.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/600\/2025-10-02\/original-image\/1617949545008.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThe value of this cable lies in its specificity for solar applications and the convenience of its ready-to-use format.\u003c\/p\u003e\n\u003ch3\u003eReuse and Low Maintenance\u003c\/h3\u003e\n\u003cp\u003eThe tinned copper construction of the core is intended to maintain reliable performance over time by resisting corrosion. The low-smoke, halogen-free material specification is part of the cable's defined build. As a component with standardised MC4 connectors, it integrates easily with many existing solar systems, and its fixed lengths prevent the waste that can come from cutting longer rolls of cable.\u003c\/p\u003e\n\u003ch3\u003eWhy Choose This Product\u003c\/h3\u003e\n\u003cp\u003eThis cable offers a direct solution for a specific need: extending solar panel connections with compatible, pre-terminated cables. It provides the core specifications—4 square mm cross-section, MC4 connectors, tinned copper core—that are sought for this task. The choice of multiple lengths and two colours adds a level of customisation to fit the physical layout and organisational scheme of your particular installation, providing a practical, off-the-shelf component for solar energy projects.\u003c\/p\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"4 square mm single-core solar PV extension cable with black MC4 connectors on both ends.\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US10\/600\/2025-10-02\/original-image\/1617949545019.webp\"\u003e\u003c\/div\u003e","brand":"qucviy-mj","offers":[{"title":"Black \/ 2M","offer_id":59520225509710,"sku":"CJSM107233402BY","price":38.98,"currency_code":"GBP","in_stock":true},{"title":"Black \/ 5M","offer_id":59520225542478,"sku":"CJSM107233404DW","price":41.98,"currency_code":"GBP","in_stock":true},{"title":"Black \/ 1M","offer_id":59520225575246,"sku":"CJSM107233401AZ","price":36.98,"currency_code":"GBP","in_stock":true},{"title":"Black \/ 3M","offer_id":59520225608014,"sku":"CJSM107233403CX","price":39.98,"currency_code":"GBP","in_stock":true},{"title":"Red \/ 5M","offer_id":59520225640782,"sku":"CJSM107233409IR","price":41.98,"currency_code":"GBP","in_stock":true},{"title":"Black \/ 10M","offer_id":59520225673550,"sku":"CJSM107233405EV","price":44.98,"currency_code":"GBP","in_stock":true},{"title":"Red \/ 1M","offer_id":59520225706318,"sku":"CJSM107233406FU","price":36.98,"currency_code":"GBP","in_stock":true},{"title":"Red \/ 3M","offer_id":59520225739086,"sku":"CJSM107233408HS","price":39.98,"currency_code":"GBP","in_stock":true},{"title":"Red \/ 2M","offer_id":59520225771854,"sku":"CJSM107233407GT","price":38.98,"currency_code":"GBP","in_stock":true},{"title":"Red \/ 10M","offer_id":59520225804622,"sku":"CJSM107233410JQ","price":44.98,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1017\/6895\/4190\/files\/1617949532820.webp?v=1777297112","url":"https:\/\/qucviy-mj.myshopify.com\/products\/mc4-connector-solar-panel-cable-single-core-photovoltaic-extension-cable-4-square-mm-tinned-copper-wire-low-smoke-halogen-free-insulation-available-in-black-or-red-with-lengths-from-1-metre-to-10-metres-for-renewable-energy-systems","provider":"Home Enjoyment","version":"1.0","type":"link"}
