5.8 Measuring several identical PV modules/ PV
strings
For PVsystems with several identical PVmodules/ PVstrings, you can compare the measured
open-circuit voltages and short-circuit currents in the measured value memory [}page19].
Requirements
• Please observe the requirements for measuring [}page24].
• The DCpolarity is correct and the DCvoltage is in the range between 5and1 000V.
• Approved safety measuring lines
• Corresponding measuring ranges [}page22]
• Stable insolation conditions
• Deleted measured value memory [}page19]
