Gossen Metrawatt PROFITEST PV [M360A] Peak Power Measuring Instrument and Curve Tracer

The PROFITEST PV allows for the measurement of characteristic I-U curves, as well as individual photovoltaic modules and strings. 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.

Features:

---

• Measurement of characteristic I-U curves at PV modules and strings up to 1000 V DC, 20 A DC and 20 kW
• Acquired characteristic I-U curve is highly accurate thanks to steady measurement at the capacitive load
• Measurement of short-circuit current Isc, open circuit voltage Uoc, instantaneous peak power of a solar cell Pmax,

      series resistance Rs and internal parallel resistance Rp

• 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

• Integrated customer database with bidirectional data exchange
• Integrated module database with bidirectional data exchange
• High level of intrinsic safety thanks to included load disconnector (1000 V / 32 A DC)
• Power and temperature measurement via four-conductor cable for error-free results
• Separate measurement of temperatures at the irradiation sensor and the back of the module (Pt100) for increased

      measuring accuracy

• Continuous display of momentary irradiation and temperature provides information regarding measuring

      conditions

• Easy touch-screen operation
• Highly luminous, high resolution color TFT display with energy-saving LED illumination (suitable for use in

      sunlight!)

• External power pack with broad-range input for charging the batteries, and for continuous operation of

      the measuring instrument

• Software for graphic representation, evaluation and documentation with integrated database
• Operation via a PC with direct import of measurements is also possible (e.g. for long-term measurements)
• Open interfaces allow for operation of the instrument in special applications as well
