1. GENERAL SPECIFICATIONS OF I-V 400 METER
HT ITALIA enlarges its range of products for photovoltaic system introducing the new I-V 400
The instrument 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
