Positive and negative, ready to fit.\u003c\/p\u003e\u003ch2\u003eWhy This Product\u003c\/h2\u003e\u003cp\u003eThe cable between your charge controller and your battery is the part of a solar system nobody photographs and everybody underestimates. Undersize it and you lose voltage across the run, which means the controller sees a lower battery voltage than is really there and stops charging early. You paid for the panels; there is no sense throwing away the yield in the last two metres. 8AWG is 8.37mm² of copper, rated to 55A under NEC guidance, which comfortably covers a Rover 30A or 40A, an Adventurer 30A or a Wanderer 30A controller. On a caravan where the controller sits near the battery box, 2.4 m is usually enough to route neatly rather than in a straight line. These are tinned copper rather than bare copper, which matters on the coast and matters anywhere a battery box gets damp. Bare copper goes green at the lug and resistance climbs; tinned copper does not.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e8AWG (8.37mm²) conductor\u003c\/strong\u003e – rated to roughly 55A, matched to 30A and 40A controllers with headroom for voltage drop.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e2.4 m (8ft) per cable\u003c\/strong\u003e – enough to route around a battery box instead of cutting corners.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3\/8 inch ring lugs at the battery end\u003c\/strong\u003e – fits standard battery terminal studs without adapters.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBare stranded tail at the controller end\u003c\/strong\u003e – goes straight into a screw terminal, no crimping required on site.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTin-plated oxygen-free copper\u003c\/strong\u003e – resists corrosion in damp battery compartments and coastal air.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTUV listed for PV solar use\u003c\/strong\u003e – UV resistant and rated for outdoor conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeat-shrink insulated terminals\u003c\/strong\u003e – abrasion resistance and no exposed copper at the lug.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupplied as a positive and negative pair\u003c\/strong\u003e – one order, both cables, correctly colour coded.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eIdeal For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConnecting a 30A or 40A MPPT or PWM controller to a caravan house battery.\u003c\/li\u003e\n\u003cli\u003eReplacing undersized factory wiring that is costing you charge current.\u003c\/li\u003e\n\u003cli\u003eCamper trailer and off-road trailer solar installs done properly the first time.\u003c\/li\u003e\n\u003cli\u003eBush cottage and farm solar setups where the controller is a couple of metres from the bank.\u003c\/li\u003e\n\u003cli\u003eAnyone who has measured a voltage drop and decided to fix it.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eLocal Support from 4Matt Campers\u003c\/h2\u003e\u003cp\u003eWe ship Renogy components anywhere in \u003cstrong\u003eSouth Africa\u003c\/strong\u003e.

The fuse protects the cable, not the controller, so size it to the cable rather than to the panel array. Strip only as much insulation as the controller terminal needs and make sure every strand goes into the clamp; a few strands folded outside the terminal is how hot spots start. Torque the ring lug onto the battery stud properly and check it again after the first long gravel trip. If your run is longer than 2.4 m, or your controller is 60A rather than 30A, step up to the 4AWG version rather than joining two of these together.\u003c\/p\u003e\u003ch2\u003eComplete Your Setup\u003c\/h2\u003e\u003cp\u003ePair it with a controller from \u003ca href=\"\/collections\/solar-charge-controllers\"\u003esolar charge controllers\u003c\/a\u003e, an array from \u003ca href=\"\/collections\/solar-panels\"\u003esolar panels\u003c\/a\u003e and a bank from \u003ca href=\"\/collections\/lithium-batteries\"\u003elithium batteries\u003c\/a\u003e.
