Fluke GFL-1500 (6021723) Solar Ground Fault Locator

Fluke GFL-1500 (6021723) Solar Ground Fault Locator

The Fluke GFL-1500 Solar Ground Fault Locator is an advanced troubleshooting system engineered to help solar technicians quickly and safely pinpoint active ground faults in PV installations. Designed for modern solar arrays up to 1500 V DC, this three-piece diagnostic toolset, comprising of a Transmitter, Receiver, and Signal Tracing Clamp. The GFL-1500 uses FaultTrack™ Technology to generate a traceable signal along the fault path, allowing non-contact detection directly to the point of failure. Unlike traditional, time-consuming fault isolation methods, the GFL-1500 enables technicians to trace faults without disconnecting conductors or dismantling string connections. Its intuitive interface and high-sensitivity receiver allow for precise, rapid fault localisation, even in large-scale PV arrays or sites with incomplete documentation, reducing downtime and improving safety. Built for real-world field conditions, the GFL-1500 is rugged, accurate, and compliant with CAT III 1500 V / CAT IV 600 V safety standards, making it the ultimate solution for maintaining system performance and uptime in high-voltage solar applications.
