peak power measuring device / with I-U characteristics measurement / benchtop / for photovoltaic systems

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 high resolution color graphic touch-screen which is suitable for use in sunlight.

- 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

- 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!)
