GFL-1500 Precision Ground Fault Locator for Solar PV Systems

The Fluke Electronics GFL-1500 solar ground fault locator is a cutting-edge diagnostic tool designed to revolutionize fault detection in solar photovoltaic (PV) systems. Engineered for utility-scale and commercial solar installations, this three-piece system comprising a transmitter, receiver, and signal tracing clamp enables technicians to quickly identify and locate active ground faults without the need for manual disconnection or brute-force testing.

At the heart of the GFL-1500 is the Fluke proprietary FaultTrack technology, which generates a traceable signal through the fault path, allowing for intuitive, non-contact tracing directly to the fault location. This dramatically reduces troubleshooting time and minimizes exposure to electrical hazards. The system is rated for CAT III 1500 V_DC and CAT IV 600 V, ensuring safe operation in high-voltage environments.

Designed for real-world conditions, the GFL-1500 features a high-visibility LCD display, audio-visual fault guidance, and multiple diagnostic modes including analyze, fault tracing, open circuit, and mapping. These functions allow technicians to assess system status, confirm string layouts, and pinpoint faults with precision even in noisy or undocumented environments.

With rugged construction, intuitive operation, and comprehensive safety compliance, the Fluke GFL-1500 empowers solar maintenance teams to restore system performance quickly and confidently, making it an essential tool for maximizing uptime and energy production.
