Solar Photovoltaic Test Equipment

Solar Energy Troubleshooting made easy

Benefits for instrument owners

The Z200 PV Analyzer has superior technical features, which leads to the following benefits:

  • Reduce the amount of time taken to locate PV system faults
  • Provide clients with a high level of testing data
  • Locate faults while also testing standard parameters
  • Quickly map out cables and modules
  • Find faults even in cloudy weather
  • Reduce truck rolls


Don’t just take our word for it, see what our customers are saying!

The equipment (2 x Z200 PV Analyzer) is working perfectly, doing exactly what we need it to do. Overall we are really happy with it and appreciate the support also.

The peculiarity of the PV Analyzer is that this instrument can both diagnose error types, which other instruments can not detect, and indicate the position of the defective components.

A Comparison of Photovoltaic Test Equipment

The challenge A range of PV testers are available on the market, but most solar PV test instruments are designed for IEC certification, efficiency testing, or Infra-Red imaging. The problem is that only very few instruments are designed for operations…


Helios Solar Operations & Maintenance

Following my purchase of the Emazys Z200, I’d like to explain why I have purchased it.Initially, I had been made aware of the fault-finding capabilities by James Hoare, who has used the Emazys Z200 for a couple of years now.I…


Photovoltaic Ground Fault Finder

What is a solar photovoltaic ground fault? According to the Photovoltaic Systems textbook (published by NJATC), a solar PV ground fault is “the condition of current flowing through the grounding conductor.”The cause of this very undesirable current flow is an…

Wire Tracer & Circuit Tester for solar PV systems

Solar panel amplifier probe and tone generator The Z200 PV Analyzer may be used much like a conventional cable tester for PV modules. The Z200 can generate frequencies that can be picked up and heard, with a handheld pickup across…


Impact of Isolation Resistance Faults in Photovoltaics

A photovoltaic (PV) array is an investment that is not subject to wear. This hypothesis might have persisted for years, however, this does not make it tenable: even carefully planned and executed arrays need monitoring, an occasional inspection, and, at…
