The AllSpark MC4 2-into-1 Branch Connectors let you wire two solar panels in parallel without the need for a combiner box, delivering a clean and reliable connection rated to 30A and 1000V DC. Built to IP67 waterproof standards, the UV-stabilised polymer housings lock together with a positive click, creating a weatherproof seal that stands up to Australian sun, dust, and driving rain whether you're parked at a remote outback camp or set up in a coastal campground. The pair includes one male branch (MFF — one male, two female ports) and one female branch (FMM — one female, two male ports), covering both positive and negative parallel connections in a single purchase.

These branch connectors are the go-to solution for Australian caravanners, RV and motorhome travellers, camper trailer owners, and 4WD adventurers who run two rooftop or folding solar panels and want to feed them into a single MPPT or PWM charge controller input. They're equally at home on a permanent roof-mounted system as they are on a portable folding panel setup at a bush camp. Compatible with standard 4mm² and 6mm² solar PV cable and any MC4-standard panel or controller, they make expanding your off-grid solar array simple and cost-effective — no tools required to mate the connectors, and a locking ring prevents accidental disconnection on corrugated tracks.
