Fluke GFL-1500 - Rapid Fault Location for Ground Faults in Solar Installations up to 1500 V DC
The Fluke GFL-1500 Solar Ground Fault Locator is designed to quickly and safely identify and locate active ground faults in solar (PV) installations. This instrument is intended for technicians, installers, and service personnel who work with troubleshooting and maintenance of modern solar installations, where downtime and inefficient fault finding can have significant financial consequences.
Using Fluke's FaultTrack™ technology, a traceable signal is injected into the system, allowing the fault location to be followed without direct contact with live parts. This reduces both troubleshooting time and exposure to electrical hazards.
Efficient Troubleshooting Without Guesswork
Traditional ground fault troubleshooting can be both time-consuming and complex. The Fluke GFL-1500 is designed to make the process more intuitive and efficient by guiding the user directly to the fault area.
The system offers four key functions:
- Ground fault analysis
- Fault location tracking
- Open circuit localization
- Mapping of string paths and system structure
This makes the instrument suitable for commissioning, service tasks, and troubleshooting on existing systems.
Designed for Modern Solar Installations
More and more solar installations are now built with 1500 V DC architecture to achieve higher efficiency and lower installation costs. This places greater demands on safety and measuring equipment.
The Fluke GFL-1500 is certified for:
- CAT III 1500 V DC
- CAT IV 600 V
This means the instrument can be used safely in both commercial and industrial solar installations, as well as larger utility-scale systems.
Complete Kit for Professional Use
The Fluke GFL-1500 is delivered as a complete system consisting of:
- GFL-1500 transmitter
- GFL-1500 receiver
- Signal clamp for tracking
- MC4 test leads for 1500 V
- Alligator clips
- MC4 release tool
- Carrying case
- Shoulder strap
- Batteries
The combination of transmitter, receiver, and current clamp allows faults to be located throughout the entire PV installation – from inverter and combiner box to modules and string connections.
