{"product_id":"dc-extension-cable-mc4-4m","title":"DC Extension Cable MC4 — 4m","description":"\u003cp\u003eThe longest MC4 extension in the range at four metres — for the awkward installs where the module and its inverter ended up genuinely far apart.\u003c\/p\u003e\n\n\u003ch3\u003eWhen you need four metres\u003c\/h3\u003e\n\u003cp\u003eDetached arrays are the usual reason. A pair of modules on a shed roof feeding an inverter mounted on the wall below. A carport section wired back to equipment on the adjacent structure. A ground-mount row where the inverter had to sit at the accessible end rather than mid-row. In each case the distance is real and structural, not a mounting compromise you can design out.\u003c\/p\u003e\n\n\u003ch3\u003eThe point where you should stop extending\u003c\/h3\u003e\n\u003cp\u003eFour metres is near the sensible limit for a module-to-inverter DC run. If your layout needs substantially more than this, the answer is usually to move the inverter rather than to keep adding cable. Microinverters are designed to live at the array — that is the entire architecture. Long DC runs back to a distant inverter reintroduce exactly the problem module-level electronics exist to eliminate, and every extra metre is more cable exposed to weather, wildlife and mechanical wear for the life of the system.\u003c\/p\u003e\n\n\u003ch3\u003ePractical notes\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eLong spans need proper support — plan the route and the fixings before you pull the cable\u003c\/li\u003e\n  \u003cli\u003eWhere the run leaves the array structure, protect it: conduit, cable tray, or routing beneath the frame\u003c\/li\u003e\n  \u003cli\u003eRodent damage to exposed PV cable is a genuine and frequently underestimated failure mode on ground mounts and outbuildings\u003c\/li\u003e\n  \u003cli\u003eKeep positive and negative together along the whole run\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eAlso available in 1m, 2m and 3m.
