Why solar professionals choose the TLPV2

Testing voltage on active PV arrays can be challenging. Solar systems must remain energized during operation, yet traditional test leads can make it difficult to safely access measurement points. The TLPV2 provides a safer, more efficient way to measure operating voltage directly on live solar strings.

The problem with standard leads on PV systems

  • Standard test leads require direct probe contact, risky ion live combiner boxes and inverters.
  • Making measurements on energized 1500V arrays with general-purpose leads introduces significant risk.
  • Limited access and awkward probe angles can make it harder to maintain secure contact during testing.

What the TLPV2 enables

  • Measure operating voltage on live solar strings, safely, in-line with the circuit.
  • Perform string Voc checks and performance diagnostics without opening the combiner box or inverter.
  • Access measurement points on energized systems where standard probes are not practical.
Real-world applications for solar technicians

String performance verification

Measure string operating voltage during peak production without shutting down the system. Quickly identify underperforming strings and potential issues before they impact performance.

Commissioning diagnostics

Use with the FLK-SMFT-1000 to perform IV curve testing and verify key solar performance parameters, including Voc, Isc, and Pmax during system commissioning.

Ongoing O&M troubleshooting

Speed up troubleshooting during maintenance visits by enabling string-level voltage measurements on operating systems, helping reduce diagnostic time and unnecessary return visits.

Ground fault investigation

Use alongside the Fluke GFL-1500 to investigate ground faults and verify system isolation on live 1500V arrays without requiring a complete shutdown.
