The PV-Checks Pro is an installation tester for photovoltaic systems, which can be used in the 1000 volt level as well as in the 1500 volt level up to a short-circuit current of 40 A DC and therefore sets new standards!
PV-Checks Pro is the complete solution for compliance with IEC 62446-1 standards (DIN VDE 0126-23) for all popular tests in category 1.
PV-Checks Pro carries out all necessary tests for commissioning a PV plant in accordance with IEC 62446-1 in automatic order on both single-sided and bi-facial PV modules.
GO-STOP BUTTON
By pressing the GO-Stop-key the following measurements are carried out one after the other:
• Polarity test
• Continuity of the equipotential bonding conductor
• Determination of the insulation resistance RISO
• Determination of the open-circuit voltage VOC up to 1500 V DC
• Determination of the short-circuit current ISC up to 40 A DC
In accordance with EN 62446-1-1, PV-Checks Pro compares the currently measured string with the previously measured strings in order to evaluate voltage and current differences that lie outside the specified tolerances.
By measuring the solar radiation (optional reference cell required) and the PV module temperature (optional temperature sensor required) with the external SOLAR 03 data logger, the PV-Checks Pro can measure the measured values of VOC-OPC and ISC-OPC on the STC (standard test conditions: 1000 W/m², 25° C, AM 1.5) to compare these with the specified nominal values from the manufacturer's module data sheets.
After each measurement, the PV-Checks Pro shows the result of the measurement in the display with the corresponding evaluation (OK/Not OK).
SPECIAL FUNCTION GFL
Localization of the isolation error on a PV string (ground fault location)
Along with the wide application range (1500 V DC / 40 A DC) the PV-Checks Pro is characterized by the new GFL function for error detection of insulation faults. With the help of the ground fault locator (GFL) function the insulation faults can not only be detected fundamentally, but can also be localized precisely. The PV-Checks Pro shows the suspected position of a fault within a string on the display.
