Fluke Corporation, an industrial tools and integrated software provider, has launched the Fluke GFL-1500 Ground Fault Locator, a breakthrough technology designed to address some of the most persistent pain points faced by solar technicians. The Fluke GFL-1500 lets solar technicians locate ground faults using non-contact tracing — reducing the need for multiple disconnections and brute-force testing of individual strings.

In utility-scale solar systems, ground faults are a common challenge often caused by environmental wear, aging infrastructure or installation quality issues. These faults can lead to costly downtime and reduced energy output.
The Fluke GFL-1500 combines the power of a signal-producing transmitter with a non-contact detection clamp and a non-contact signal receiver to help technicians pinpoint the location of active ground faults. Fluke GFL-1500 is capable of identifying the faulted branches and locations within a string without relying on site maps or test procedures.
“The Fluke GFL-1500 marks a pivotal advance in non-contact ground-fault troubleshooting for solar technicians,” said Vineet Thuvara, chief product officer at Fluke. “With solar generation surging 30% globally last year — the fastest annual growth since 2017 — there’s more urgency than ever to restore systems swiftly when faults occur. The GFL-1500 cuts through uncertainty, enabling technicians to pinpoint and resolve issues fast, minimize expensive downtime and keep clean energy flowing. It’s built from on-the-ground insights to tackle the real challenges of today’s booming solar industry.”
Fluke GFL-1500 is compatible with 1,500-V PV systems and is designed to locate ground faults between the inverter and module. Fluke will be exhibiting at RE+ at booth V2065 from September 8 to 11 in Las Vegas.
