In solar power systems, attaching and detaching PV cable connectors (MC4 terminals) is an essential task. Traditionally, installers had to switch between different specialized tools depending on the manufacturer and specifications, creating inefficiencies and management challenges.

GBP developed this multifunctional MC4 connector tool to solve those issues. By supporting leading terminal brands such as Stäubli, LONGi, and Jinko, the tool enables connection and disconnection work with a single device. This reduces tool-switching during installation, greatly improves efficiency, and simplifies on-site tool management.

・Compatible with Stäubli MC4 / MC4-EVO2
Works with both MC4 (1000V) and MC4-EVO2 (1500V), commonly used in solar power plants. This reduces the need to switch tools between projects.

・Supports Multiple Manufacturers
Compatible with connectors from Stäubli, LONGi, Jinko, QC Solar, Tongwei, and others. With one tool, installers can handle a wide variety of terminals, eliminating the need for multiple tools on site.

・Slide Structure to Prevent Overtightening
Once a certain torque is reached, the tool automatically slides, preventing further tightening. This design minimizes terminal damage while improving safety and repeatability.
