The AllSpark MC4 3-Into-1 Branch Connectors make it straightforward to connect three solar panels in parallel to a single charge controller input — maximising your solar harvest without rewiring your entire system. Built to the universal MC4 standard with a 4 mm diameter contact pin, these connectors feature an IP67-rated weatherproof housing that locks securely by hand and requires a tool to separate, preventing accidental disconnection from road vibration or heavy weather. The parallel wiring configuration maintains your system voltage while combining current output from all three panels, and the UV-resistant polymer housing is rated up to 1000 V DC and 30 A — well within the demands of Australian outback and coastal solar setups.

Ideal for Australian caravanners, RV owners, and 4WD adventurers looking to expand their solar capacity without replacing their existing charge controller, these branch connectors are compatible with cable gauges from 2.5 mm² to 6 mm² and work with virtually any MC4-type solar panel or MPPT/PWM regulator on the market. Whether you're wiring a rooftop caravan array, linking portable folding panels on a remote campsite, or building out a 4WD canopy solar system for extended off-grid travel, this pair of MFFF and FMMM connectors gives you a clean, professional connection with zero tools needed for installation.
