PROFITEST PV
Peak Power Measuring Instrument and Curve Tracer for
PV Modules and Strings (Measurement at Capacitive Load)
2 GMC-I Messtechnik GmbH
Regulations and standard in accordance with which the test instrument is
manufactured and tested:
Regulations and Standards for Use of the Test Instrument
Characteristic Values
The measuring ranges can be combined with each other. The
measuring instrument automatically selects the ideal measuring
range.
Computer Unit
Miniature industrial PC, real-time clock, no moving mechanical
parts such as hard disks, fans etc.
A-D sampling rate: max. 100 kHz, resolution: 12 bit
Measuring accuracy for characteristic I-U curve better than 1%,
peak power ±5%
Data from several thousand measurements are automatically
saved at the device permanently (flash memory)
Measuring Unit
Sampling rate Max. 100 kHz,
Resolution 0.01 to 0.25 V, 0.005 to 0.001 A
(depending on selected measuring range)
Measuring accuracy Better than 1%
Ascertainment of Peak Power
Tolerance ±5%
Reproducibility ±2%
Measurement duration for separate measurement of individual
modules: > 20 ms (approx. 100 pairs of measured values), and
thus the capacitive characteristics of the device under test have
no influence on measurement.
• 4-conductor measurement cable to the generator prevents
systematic voltage measuring errors
• Irradiation reference sensor (Phox) with integrated Pt1000
temperature sensor
• Supplementary measurement of temperature at the back of
the module is possible (a second Pt100 input is provided)
• Commercially available reference sensors such as the ISET-
Sensor
® can be connected via interference-free cable con-
nection
• Connection is only permissible to direct voltage sources with
current limiting (e.g. photovoltaic generators)
