Gossen Metrawatt PROFITEST PV Testers for PV Modules and Strings

Benefits of the Gossen Metrawatt PROFITEST PV Testers for PV Modules and Strings

• Test device for testing PV modules and strings.
• Model PV for peak power and characteristic.
• Model PVSUN for safety testing according to DIN EN 62446 (VDE 0126-23).

GMC-I/Gossen Metrawatt PROFITEST PV Peak Power Measuring Instrument and Curve Tracer for PV Modules and Strings

The GMC-I/Gossen Metrawatt PROFITEST PV (M360A) allows for the measurement of characteristic I-U curves, as well as individual photovoltaic modules and strings(measurement at capacitive load). With the help of a patented process, the instrument is capable of ascertaining peak power, internal series resistance and internal parallel resistance directly on-site with only one measurement and without entering module data, which are then indicated at a highresolution color graphic touch-screen which is suitable for use in sunlight. Troubleshooting in PV systems, as well as documentation of system quality, are executed quickly and economically during initial start-up and subsequent testing without a long learning curve. This simple yet decisive test assures safety for the customer and eliminates consequential costs for the installer. Measured peak power can, for example, also be used in order to determine peak ratio. Beyond this, acquired characteristic curves make it possible to draw further conclusions regarding the electrical characteristics of the measured module or string. And thus the instrument is also suitable for R&D.

• Generator voltage up to 1000 VDC, current up to 20 ADC.
• Measurement of short-circuit current I_SC, open circuit voltage U_OC, instantaneous peak power of a solar cell P_max, internal series resistance R_S, and internal parallel resistance R_P.
• Automatic conversion of momentary measured values to STC.
• Patented calculation process for evaluating PV generators without knowledge of the manufacturer's specifications.
• Patented calculation process for determining the generator's internal series resistance based solely on a measured characteristic I-U curve.
• Separate measurement of temperatures at the irradiation sensor and the back of the module for increased measuring accuracy.
• High level of intrinsic safety thanks to included load disconnector (1000 V/32 ADC) for all-pole disconnection of the measuring instrument from the PV generator.
• Calibrated irradiation sensor per IEC/EN 60904-2 with integrated Pt1000 temperature sensor.
• Integrated customer database with bidirectional data exchange.
• Integrated module database with bidirectional data exchange.
• Software for graphic visualization, evaluation and report generation with integrated database.
