The PROFiTEST-PV permits measurement of characteristic IU curves from individual photovoltaic modules, as well as from strings.
Switch On > Start Measurement > Read Results > Done!
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 displayed at a high resolution color graphic touch-screen that’s suitable for use in sunlight.
Generator voltage up to 1500 V DC, current up to 20 A DC
Measurement of short-circuit current ISC, open circuit voltage
UOC, instantaneous peak power of a solar cell Pmax, internal 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 single characteristic IU curve
Separate measurement of temperatures at the irradiation sensor and the back of the module for increased measuring accuracy
Measurement of insulation resistance using nominal voltage, with rising test voltage
High level of intrinsic safety thanks to included load disconnector (1500 V/20 A DC) 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 representation, evaluation, error analysis and documentation with integrated database
