The I-V 400 allows the on field measurement of I-V curve as well as of the main parameters of a single module and of a whole photovoltaic system up to a maximum of 1000V and 10A.

The acquired data are then worked out and transferred to the reference conditions (STC) in order to compare them with the rated data declared by the manufacturer of those modules. The comparison between the detected and the rated data permits to immediately determine whether the string or the module respect the parameters declared by the manufacturer.

The instrument allows to perform quick tests (IVCK) to measure the open voltage Voc and short circuit current Isc on PV module/strings output also without irradiation conditions I-V 400 manages an internal database of the most common photovoltaic modules. Such a database can be updates at any time by the user both through the management software and directly through the instrument's interface.
