MC4 Solar Panel Connectors with 12A Fuses | Voltacon

This pair of MC4-compatible solar panel connectors includes integrated 12A fuses, giving overcurrent protection on both PV string lines without needing a combiner box. They suit smaller solar panels and off-grid systems, and each connector takes 2.5mm² to 6mm² solar cable with a replaceable fuse cartridge.

Key features of these mc4 solar panel connectors

• Set contents, 1 male and 1 female MC4-compatible connector
• Fuse rating, 12A fast-acting fuse built into each connector
• Line coverage, protects both positive and negative PV lines
• Fuse cartridge, replaceable
• Cable compatibility, 2.5mm² to 6mm² solar PV cable
• Build, waterproof construction for outdoor use

Applications

Use these connectors for PV string overcurrent protection where a combiner box isn't fitted. They also suit small off-grid solar systems built around panels with lower short-circuit current.

Installation notes

DC solar circuits carry dangerous voltages. All wiring must comply with IET Wiring Regulations, and the fuse rating must match the string short-circuit current before the system is energised.
