Key Terms

cat iii, cat iv, photovoltaic

3 terms

cat iii technical

"CAT III 1500 V / CAT IV 1000 V safety ratings"

Category III (Cat III) designates the highest regulatory risk class for medical devices under many national systems, covering devices that sustain or support life, are implanted, or present a high potential for harm if they fail. It matters to investors because Cat III products face the most stringent testing, longer approval timelines, and higher development costs—like building a bridge rather than a footpath—while also often creating larger market barriers and potential returns if approved.

cat iv technical

"CAT III 1500 V / CAT IV 1000 V safety ratings"

CAT IV is an electrical safety rating from international standards that marks equipment meant for the highest-energy parts of a power system, such as the service entrance, utility lines, or industrial feeders. It tells buyers and regulators that meters or test tools can handle large transient voltages and protect users in the most demanding locations; for investors, a CAT IV rating signals that a product meets strict safety and market requirements for heavy-duty electrical applications, which can affect market acceptance and liability exposure.

photovoltaic technical

"measure operating voltage on energized photovoltaic (PV) systems"

Photovoltaic describes the technology that converts sunlight directly into electricity using panels made of semiconductor materials; think of it like leaves turning sunlight into usable energy for a plant, but producing power for homes, factories and the grid. It matters to investors because photovoltaic systems represent assets, revenue sources, cost structures and regulatory exposure for energy and manufacturing companies, and their adoption rates and efficiency gains affect long-term profitability and market demand.

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.
