FAQ
Q: Can GDPV-IV test bifacial PV modules?
A: Yes. GDPV-IV can test both monofacial and bifacial PV modules. For bifacial modules, it is recommended to measure the irradiance on both front and back surfaces and input the albedo value for more accurate STC correction.
Q: How does the built-in module database work?
A: The instrument pre-stores the temperature coefficients, irradiance coefficients and nominal parameters of over 200 mainstream PV module models from major manufacturers. During testing, you can select the corresponding module model from the database, and the instrument will automatically use the correct coefficients for STC correction, eliminating the need for manual parameter input. You can also manually add new module models to the database.
Q: Can GDPV-IV test PV strings without disconnecting them from the inverter?
A: No. For safety reasons, PV strings must be disconnected from the inverter and other electrical equipment before testing. The instrument is equipped with comprehensive protection functions including reverse polarity protection and over-voltage protection to prevent damage caused by incorrect connection.
