{"product_id":"renogy-20a-waterproof-inline-solar-fuse-holder","title":"Renogy 20A Waterproof In-Line Solar Fuse Holder with Fuse","description":"\u003ch2\u003eShort Product Summary\u003c\/h2\u003e\u003cp\u003eA 20A fuse sealed inside a waterproof in-line holder, with a standard solar connector on each end. It plugs straight into a panel lead or an adaptor kit, no cutting and no crimping, and gives a solar string proper over-current protection out on the roof where the weather is.\u003c\/p\u003e\u003ch2\u003eWhy This Product\u003c\/h2\u003e\u003cp\u003eString fusing is the part of a solar install that gets skipped because it seems optional on a single panel. It stops being optional the moment you wire two or more panels in parallel. In a parallel array, a fault in one panel can be back-fed by all the others, and the only thing limiting that current is the fuse in that string. On a caravan roof that is not an academic concern; it is a live 1000V-rated DC circuit sitting in the sun above your bed. This holder makes the fix trivial. It has a solar connector on each end, so it clicks into an existing panel lead in seconds and comes apart just as easily when you want to isolate a string for fault-finding. IP67 sealing and a PPO body mean it can live outside permanently, and the fuse itself is replaceable rather than the whole unit being disposable.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e20A rated fuse in a sealed holder\u003c\/strong\u003e – correct protection for typical caravan and camper solar strings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSolar connector on each end\u003c\/strong\u003e – plugs into panel leads and adaptor kits without cutting or crimping.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIP67 rated sealing\u003c\/strong\u003e – designed to sit permanently on a roof through rain, dust and sun.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1000V DC rated\u003c\/strong\u003e – far beyond anything a 12V or 24V caravan array will present.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReplaceable fuse\u003c\/strong\u003e – change the element instead of throwing away the holder.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSilver-plated copper contacts\u003c\/strong\u003e – low contact resistance that stays low over years outdoors.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePPO insulation, UL94-V0 flame class\u003c\/strong\u003e – self-extinguishing material rather than ordinary plastic.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAuto-lock plug and play connectors\u003c\/strong\u003e – positive click when mated, no accidental separation on corrugations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide operating range from -40°C to +125°C\u003c\/strong\u003e – covers a black roof in the Kalahari and a frosty Karoo morning.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eIdeal For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFusing individual strings in a parallel solar array on a caravan or camper roof.\u003c\/li\u003e\n\u003cli\u003eAdding protection to a portable panel or suitcase feed.\u003c\/li\u003e\n\u003cli\u003eProviding an easy disconnect point for fault-finding on a roof array.\u003c\/li\u003e\n\u003cli\u003eOff-road trailers where the array is exposed to dust and water crossings.\u003c\/li\u003e\n\u003cli\u003eBush cottage and farm solar wiring that needs to be weatherproof and inspectable.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eLocal Support from 4Matt Campers\u003c\/h2\u003e\u003cp\u003e4Matt Campers delivers genuine Renogy parts across \u003cstrong\u003eSouth Africa\u003c\/strong\u003e.

Only one per string is needed. If you are running a single panel straight into a controller, string fusing is not strictly required, though it still gives you a convenient disconnect. Route the holder so it hangs below the connectors rather than above them; water runs downhill and you want it running away from the seals, not into them. When you replace a blown fuse, work out why it blew before you refit; a solar string that blows a 20A fuse has either a wiring fault or more panels on it than you thought. Keep the dust caps on any unmated connector.\u003c\/p\u003e\u003ch2\u003eComplete Your Setup\u003c\/h2\u003e\u003cp\u003eUse it with panels from \u003ca href=\"\/collections\/solar-panels\"\u003esolar panels\u003c\/a\u003e, branch connectors and extension leads from \u003ca href=\"\/collections\/electrical-accessories\"\u003eelectrical accessories\u003c\/a\u003e, and a regulator from \u003ca href=\"\/collections\/solar-charge-controllers\"\u003esolar charge controllers\u003c\/a\u003e.
