3-way MC4 Y splitter for solar panel wiring, designed to connect multiple panels in parallel while maintaining a clean, reliable and serviceable installation. Compatible with standard 4mm² solar cables, this splitter allows quick expansion of your system without modifying existing wiring.
This 3-way MC4 splitter set includes:
• 1x (1 Male → 3 Female)
• 1x (1 Female → 3 Male)
It allows you to combine up to 3 solar panels in parallel, making it ideal for 12V systems or installations requiring stable voltage with increased current output.
Using MC4 Y connectors simplifies your wiring logic:
• no need for junction boxes
• faster installation on board or off-grid
• easy system upgrades (add/remove panels anytime)
This is particularly useful on boats, vans and off-grid setups where space and accessibility are limited.
Built for outdoor and marine environments, these connectors ensure long-term reliability:
• IP67 waterproof rating
• UV and heat resistant insulation
• secure MC4 locking system
Connections remain stable even under vibration, humidity and temperature variations.
The cable uses H1Z2Z2-K solar wire (4mm²), ensuring:
• low resistance and minimal losses
• high flexibility for tight installations
• compatibility with standard MC4 tooling
Rated up to 1000V DC / 30A, suitable for most marine and off-grid solar systems.
• Parallel wiring of 2 to 3 solar panels
• 12V battery charging systems
• Boat solar installations (roof, bimini, arch)
• Van / RV solar setups
• Off-grid energy systems
