MC4

MC4 connectors are the world’s most widely used photovoltaic plug connectors and the industry standard for solar module wiring. They provide safe, weatherproof, and low-loss connections between modules, strings, and inverters. Originally developed by Multi-Contact (now Stäubli), MC4 connectors set the benchmark for reliability and electrical safety in PV systems.

Featuring a locking mechanism and UV-resistant housing, MC4 connectors are ideal for outdoor installations. Rated up to 30 A and 1000 V DC, they ensure long-lasting, secure performance and full compliance with international PV standards. A must-have for any professional solar installation.
