Solar PV test instrument from EmaZys Technologies

Unique solar photovoltaic fault finding technology

Designed and made in Denmark


A new instrument for solar PV system troubleshooting
The Z100 PV Analyzer measures the position of a range solar PV system faults and the solar photovoltaic test equipment is suitable for working faster during solar PV operations and maintenance.

The Z100 PV Analyzer works well under low light conditions and it is therefore possible to perform O&M and service tasks in almost any weather. The Z100 PV Analyzer records useful information in the field and typical faults are found within 3 minutes after arriving at the PV system terminals. This increases productivity of the PV service team and leads to work time reductions of up to 40%.

The Z100 PV Analyzer focuses on measuring the position of PV system faults causing energy losses. Finding a PV fault, eg ground faults, disconnections and degraded modules, is normally tricky and time-consuming. The Z100 PV Analyzer offers a fast and convenient way to systematically detecting and locating problems.



  • Z100 PV Analyzer - customer benefits

    • Measure the position of PV system faults in “one click”
    • Reduce man-hour consumption during testing and troubleshooting
    • Reduce solar energy loss caused by PV system downtime and faults
    • Reduce service team transport costs
    • Reduce expenses for scaffolds and lifts when testing BIPV
    • Share test results directly from instrument to cloud
    • Perform service and test PV systems even in cloudy weather
