This is the size you fit on the main battery feed to a 2000W or 3000W inverter, or on the trunk cable of a large lithium bank.\u003c\/p\u003e\u003ch2\u003eWhy This Product\u003c\/h2\u003e\u003cp\u003eOnce you install an inverter of any real size, the DC side of your caravan starts carrying currents that would be at home in a starter motor circuit. A 2000W inverter on a 12V bank pulls close to 180A continuous and considerably more on surge. Cable that size does not blow gracefully; if it shorts against a chassis rail on a corrugated road, it welds. That is what this fuse is for. A 300A ANL sits between the battery and the heavy cable, and if the worst happens it clears the fault before the cable becomes the fuse. It has a 600A interrupt capacity, so it can break a genuine lithium bank short rather than arcing across and continuing to conduct. The clear cover keeps the studs out of harm's way in a crowded battery box. It is worth saying plainly: fitting an inverter without a main DC fuse is the single most common dangerous shortcut we see in second-hand trailers.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e300A ANL fuse and holder supplied together\u003c\/strong\u003e – the complete assembly, not a fuse you then have to find a home for.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e600A interrupt capacity\u003c\/strong\u003e – clears a hard short on a lithium bank safely.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e72V voltage rating\u003c\/strong\u003e – suitable for 12V, 24V and 48V systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClear non-conductive cover\u003c\/strong\u003e – protects the exposed studs from tools, cable ends and curious fingers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIgnition protected\u003c\/strong\u003e – approved practice for caravans, boats and enclosed compartments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlloy and brass copper construction\u003c\/strong\u003e – low resistance across the studs so the joint does not run hot.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompact 123 x 40 x 37 mm holder\u003c\/strong\u003e – fits alongside a battery in most caravan battery boxes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHolder takes the full Renogy ANL fuse range\u003c\/strong\u003e – resize the circuit later and keep the holder.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoHS compliant\u003c\/strong\u003e – built to recognised environmental standards.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eIdeal For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eMain DC protection for a 2000W or 3000W inverter installation.\u003c\/li\u003e\n\u003cli\u003eTrunk fusing on a large lithium house bank.\u003c\/li\u003e\n\u003cli\u003eHigh-current DC-DC charger feeds on off-road trailers.\u003c\/li\u003e\n\u003cli\u003eCaravan and camper rebuilds where the original wiring had no main fuse at all.\u003c\/li\u003e\n\u003cli\u003eOff-grid cottage and farm systems with heavy battery cabling.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eLocal Support from 4Matt Campers\u003c\/h2\u003e\u003cp\u003e4Matt Campers supplies Renogy gear nationwide across \u003cstrong\u003eSouth Africa\u003c\/strong\u003e. A 300A fuse is only correct if your cable can carry 300A, so before you order, check the gauge of the cable it will protect. If you are not sure, phone us with the cable size and the inverter rating and we will tell you the right fuse.

At 300A the quality of the joint matters: torque the ring lugs evenly, use lugs sized to the cable, and re-check them after the first long gravel run. Do not fit a 300A fuse on cable that cannot carry 300A. If the inverter is 1000W rather than 3000W, a smaller ANL is the correct choice and this one will happily let your cable burn before it opens. Keep the cover fitted, and keep the holder out of the direct path of anything that might be thrown around in the battery box.\u003c\/p\u003e\u003ch2\u003eComplete Your Setup\u003c\/h2\u003e\u003cp\u003eUse it with heavy inverter cable and fuse cable from \u003ca href=\"\/collections\/electrical-accessories\"\u003eelectrical accessories\u003c\/a\u003e, a bank from \u003ca href=\"\/collections\/lithium-batteries\"\u003elithium batteries\u003c\/a\u003e and a unit from \u003ca href=\"\/collections\/inverters-inverter-chargers\"\u003einverters and inverter chargers\u003c\/a\u003e.
