New Y-style MC4 test leads enable safer operating voltage measurements on live PV systems without opening energized enclosures
The new Fluke TLPV2 Solar Test Lead Set from Fluke Corporation gives solar technicians a safer way to measure operating voltage on energized photovoltaic (PV) systems without opening electrical enclosures or working around exposed live connections. Designed to enable touch-safe voltage measurements directly from PV module connections, the TLPV2 helps technicians capture critical performance data while systems remain operational.
As solar installations continue to grow in size and complexity, safely troubleshooting energized systems has become more critical than ever. Featuring a unique Y-style design with official Stäubli MC4 connectors that install directly in-line with PV modules, the Fluke TLPV2 Solar Test Lead Set transforms how technicians test live solar systems. It enables touch-safe operating voltage measurements and faster diagnostics while systems remain energized, all without opening live electrical enclosures or increasing exposure to electrical hazards.
The TLPV2 represents a new approach to PV troubleshooting, one that delivers the visibility technicians need while reducing exposure to energized equipment. We’re helping customers solve problems faster while raising the standard for safety across the solar industry.
