Fluke Corporation, a top brand in industrial tools and software, unveils the Fluke GFL-1500 Ground Fault Locator. This tool is a game-changer for solar energy technicians. This innovative tool tackles a critical challenge in the industry. The GFL-1500 quickly and safely finds ground faults. It uses non-contact tracing, so you don’t need multiple disconnects or hard string tests.
Ground faults pose a big risk in utility-scale solar setups. They often happen due to wear from the environment, old infrastructure, or installation errors. Between 2011 and 2023, they caused 4% of all workplace electrical fatalities. These faults lead to unplanned downtime. They reduce energy output and pose safety risks for maintenance teams.
The Fluke GFL-1500 revolutionizes fault detection, empowering technicians to work faster and safer. This minimizes disruptions and ensures a steady supply of clean energy to the grid.
The GFL-1500 combines a signal-generating transmitter, non-contact clamp, and signal receiver. It finds the exact spot of active ground faults, even in tricky solar arrays. This design helps users find the affected branch or string easily. They don’t need detailed site plans or a lot of manual testing. This saves time in the field.

“The Fluke GFL-1500 represents a breakthrough in non-contact ground fault location for solar energy technicians,” said Vineet Thuvara, product manager at Fluke. “With global solar power generation increasing by 30% last year-the fastest annual growth since 2017-restoring systems quickly when faults occur is more urgent than ever. The GFL-1500 eliminates the guesswork, allowing technicians to quickly detect and resolve problems, minimize costly downtime, and keep clean power flowing. It was designed with field experience in mind to address the real challenges of today’s booming solar energy industry.”
Fluke launched the GFL-1500 to enhance safety and reliability in renewable energy for workers. Fluke helps solar pros find faults quickly and without downtime. This lets them provide efficient, strong, and sustainable energy solutions.
