HT Instruments PV SERVICE-PACK W5 PV multimeter Digital Graphics display

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 the optically isolated interface or via W-LAN and evaluated for further processing (protocol). The I-V400w has a database with the characteristics of the most common PV modules. This database can be extended or updated at any time by the user directly as well as via the PC interface with THE TOPVIEW* software.PV-ISOTEST• Insulation measurement up to 1,500V DC even on live systems• Localization of the insulation fault on a PV string by the new GFL function• Low ohm measurement (protective conductor) with a test current 200mA• Measurement of polarization index (PI) and dielectric absorption ratio (DAR)• Measurement of AC voltage components in the PV stringPV-ISOTEST is a real innovation in our exclusive range of PV meters!The PV-ISOTEST determines the insulation resistance of a single module, a string or even an entire PV field with a test voltage up to 1500V DC according to the EN62446 (VDE0126-23).Due to the presence of the string voltage, conventional insulation measuring devices require a suitable adapter to short-circuit the positive and negative connections of the PV string to be tested. Using PV-ISOTEST does not require the use of an external device. The PV-ISOTEST performs the insulation measurements in full autonomy and self-sufficiency. In addition, the PV-ISOTEST also shows you the exact position of an insulation fault in a string of the PV system using the new GFL function (Ground Fault Locator).
