Staubli MC4 Solar Connectors (Pair — Male & Female, Pins Included)
These authentic Staubli MC4 connectors are the professional standard for solar wiring. Each set includes both the male and female housings plus matching pins, built for long-term reliability in harsh outdoor environments. Rated for 30A continuous current, they provide industry-leading conductivity, weather sealing, and durability.
With self-sealing cable glands and IP68 O-ring protection (when mated), these connectors keep out dust and water even in demanding off-grid, RV, marine, and commercial applications. Designed for 12–10 AWG solar cable, they crimp, lock, and snap together securely for a perfect fit.
Why You’ll Love These
- Official Staubli product — unmatched quality, conductivity, and durability.
- Complete set — includes male + female housings and pins.
- Rated for 30A — safe for high-power solar systems.
- IP68 waterproof when mated — long-lasting environmental protection.
- Self-sealing cable gland — tight strain relief with no extra fittings needed.
- Rugged construction — UV stabilized, corrosion resistant, outdoor rated.
For best results, ensure your connectors match on both the panel and cable side. On high-power systems, many professionals cut off the factory connectors and install a matching Staubli pair on both ends. This guarantees proper fit, reduces resistance, and avoids mismatched tolerances between brands.

Had what I wanted and sent it fast! Thank you.
It’s good knowing these are authentic and not a cheap imitation. I don’t want any risk of fire. These fit tight and are working wonderfully
