Tracing of characteristic IU curves at PV modules and strings up to 1500 V DC, 40 A DC and 30 kW

 

The acquired characteristic IU curve is highly accurate thanks to consistent 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 instantaneous 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

 

High level of intrinsic safety thanks to included load disconnector (1500 V / 40 A DC)

 

Power and temperature measurement via 4-wire cable for error-free results

 

Separate measurement of temperatures at the irradiation sensor and at 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
