Z200 PV Analyzer - all you need for PV testing and fault finding

Solar Panel Testing Kit

Z200 PV Analyzer - designed for PV troubleshooting

The PV Analyzer Z200 is a portable and battery powered instrument used to detect and locate faults in strings of series connected photovoltaic modules. The instrument is connected to the string terminals e.g. at the string inverter or combiner box and also to the ground reference for the PV installation. 

Once connected and activated, it will perform impedance spectroscopy between any two of the three connected terminals, as well as measure the terminal voltages and currents flowing under various DC loads introduced by the instrument. By combining the results from these various measurements using the on-board computer, critical faults in the system can be defined and positioned.

Customer feedback

The reporting and trending on the Emazys (Z200) is excellent. It is a very fast and effective testing methodology with very good output report!
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.
Using the Z100, we were able to detect and locate solar PV modules with defective bypass diodes faster than using an I-V tracer.
The Z100 PV Analyzer has fully lived up to my expectations and is now my preferred service instrument for troubleshooting solar PV installations.
