เครื่องทดสอบระบบโซลาร์ Z200 PV Analyzer Smart PV Troubleshooting and Testing

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 unintentional electrical connection between a current-carrying conductor in the PV array, and the equipment grounding conductor. In other words, electric current that was supposed to flow to the inverter, or combiner box, flows directly to the ground terminal. Above a certain current threshold, the inverter shuts down entirely for obvious safety reasons.

The webinar will cover:

§ Preventive and Predictive Maintenance of PV

§ Solar ground fault troubleshooting

§ Periodic solar panel Riso faults

§ Solar PV systems are not maintenance free

§ Reduce the ground fault troubleshooting costs

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.
