Fluke 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 enables solar technicians to locate ground faults quickly, safely, using non-contact tracing—reducing the need for multiple disconnections and brute-force testing of individual strings.

In utility-scale solar systems, ground faults, which were responsible for 4.0% of all workplace electrical fatalities from 2011 to 2023, are a common challenge often caused by environmental wear, ageing infrastructure, or installation quality issues. These faults can lead to costly downtime and reduced energy output. By streamlining the fault-finding process, the Fluke GFL-1500 allows technicians to work more safely, faster, and without disruption – ensuring continuous clean energy production.

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 quickly and accurately pinpoint the location of active ground faults, even on complex arrays. The Fluke GFL-1500 enables technicians to identify the faulted branch and pinpoint the fault location within a string, without relying on detailed site maps or time-consuming test procedures.
