HT Instruments Solar Perfection Tracer
I-V400w allows field detection of I-V Curve an of the main characteristic parameters both of a single module and of strings of modules for PV installations up to a maximum of 1000V and 10A. For measuring I-V Curve, I-V400w manages an internal database of the modules, which can be updated at any time by the user and comparison between the measured data with the rated values allows immediately evaluating whether the string or the module fulfills the efficiency parameters declared by the manufacturer. I-V Curve can be measured also by decentralizing measurement of irradiation and temperature by using the optional remote unit SOLAR02, using the radio frequency connection (RF) with the master unit.
Also for I-V400w, the display at the end of the test of I-V Curve is a clear indication about the compliance with the specifications declared by the panel manufacturer.
Immediate recording of the I-V characteristic and of the characteristic parameters
I-V400 carries out the field measurement of the I-V characteristic and of the main characteristic parameters both of a single module and of module strings on PV plants (up to a maximum of 1000V and 10A).
Immediate compliance test result
The acquired data are then processed to extrapolate the I-V characteristic under standard test conditions (STC) in order to proceed comparing them with the rated data declared by the modules’ manufacturer, thus immediately determining whether or not the string or the module under test comply with the characteristics declared by the manufacturer. On the other hand the analysis of IV curve permits to detect any fault condition on each single module composing the string under test.
Remote irradiation and temperature measurement
Irradiation and temperature measurements play an essential role for extrapolation of the I-V characteristic under standard test conditions. I-V 400 carries out such measurements directly or under remote mode through the optional unit SOLAR-02, synchronized with main unit. I-V 400 can effect measurements at the inverter, while SOLAR-02 simultaneously detects environmental values close to modules without using long cable extensions.
Friendly use with possibility of continuous updating of PV modules
I-V 400 manages a database of PV modules, which can be updated at any time both via the management software and directly on the instrument through the user interface.
Very accurate measurements even using cable extensions
Current and voltage measurements on modules or strings are effected with the 4-terminal method, which allows extending measuring cables without requiring any resistance compensation, so providing accurate and precise measurements.
