I-V500wThe I-V500w enables the determination of the current-voltage characteristic curve of individual photovoltaic modules as well as of a module string up to max. 1500 V and 15 A. The current power (MPP), peak power, short-circuit current and open-circuit voltage are displayed on the graphic display by simply pressing a button and are automatically converted to standard test conditions (STC). The measured I-U and performance characteristic converted to STC are also displayed. From the comparison between the measured and specified characteristic curve of the manufacturer (up to 35 modules with their technical data can be stored simultaneously in the module database of the I-V400w), conclusions can be drawn immediately about the current quality status of the PV modules. The measured data and the characteristic curve can be stored in the I-V400w after the measurement with 3 reference numbers (system, string, module number) and text comment and transferred to the PC or iPad/tablet via th
