Gossen Metrawatt PROFITEST PV Peak Power Measuring Instrument and Characteristic Curve Tracer
The PROFiTEST PV allows for the measurement of characteristic I-U curves, as well as individual photovoltaic modules and strings.
- Measurement of characteristic I-U curves at PV modules and strings up to 1000VDC, 20ADC 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 specifications.
- Patented calculation process for determining the generator 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 (1000V / 32A 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
