I-V Curve Tracer for maintenance and troubleshooting of photovoltaic systems.

• Measurement of I-V Curve of one or more modules or of one whole string up to 1000V/15A

• Measurement of open-circuit voltage and short-circuit current Voc/Isc

• Database of 30.000 selectable photovoltaic modules

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 15A. 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.
