The AllSpark Inline MC4 Fuse 10A is a purpose-built overcurrent protection device designed to integrate directly into your solar panel wiring without breaking the sealed MC4 connector system. Rated at 10 amps and compatible with 12V and 24V DC solar arrays, it features a weatherproof UV-stabilised housing and a genuine MC4-compatible male/female connector pair — ensuring a secure, waterproof connection in the field. The replaceable fuse element sits inside a twist-lock holder, so you can swap a blown fuse in minutes without tools or crimping equipment.

Essential for caravan solar setups, rooftop 4WD installations, and off-grid motorhome systems, this inline fuse protects your charge controller, solar panels, and wiring from short circuits and overcurrent events on the road or at a remote campsite. It is ideal for use on a single panel in a series or parallel array where individual string protection is required — a best-practice wiring approach endorsed by Australian solar installation standards. Whether you are building a new caravan electrical system from scratch or upgrading an existing RV rooftop array, the AllSpark Inline MC4 Fuse 10A is a compact, cost-effective safeguard for your entire solar investment.
