New Y-style MC4 test leads enable safer operating voltage measurements on live PV systems without opening energized enclosures
Eindhoven, Netherlands, July 21, 2026 (GLOBE NEWSWIRE) -- 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.
"As solar systems become more complex, the tools technicians rely on must evolve to make safety non-negotiable," said Will White, Senior Solar Product Manager at Fluke. "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."
The Fluke TLPV2 delivers several key benefits for solar installation, maintenance and troubleshooting professionals:
- Improved technician safety by enabling operating voltage measurements without opening energized combiner boxes or inverters.
- Touch-safe testing with official Stäubli MC4 connectors and fully shrouded banana plug connections.
- CAT III 1500 V / CAT IV 1000 V safety ratings for use in demanding solar environments.
- Real-time operating voltage measurements that help technicians diagnose performance issues while systems are actively generating power.
- Compatibility with Fluke solar measurement tools, including the Fluke 393 FC Solar Clamp Meter, 283 FC/PV multimeter, and other meters accepting 4 mm shrouded banana plugs.
- Durable gold-plated contacts designed for long service life and reliable performance in the field.
- Included PV unlocking tool for safe disconnection of MC4 connectors during maintenance activities.
The TLPV2 Solar Test Lead Set is ideal for PV system commissioning, inverter verification, troubleshooting, maintenance inspections, energy audits and system performance evaluations where operating voltage measurements are required.
