HT Italia S.r.L. products

Multifunction instrument for testing and verifying single-phase PV installations. SOLAR I-V has been designed to meet any requirement of photovoltaic installation testers. Further to providing the possibility of testing and measuring the efficiency of single-phase photovoltaic systems and also measures the I-V characteristic both of a single module and of module strings. Thanks to SOLAR I-V, the operator can test the photovoltaic system and, should it give a negative result, immediately identify the problems of the system in order to promptly solve them. SOLAR I-V is provided with the remote unit SOLAR-02 for measuring irradiation and temperature. The synchronization between main unit and remote unit, by radio-frequency (RF) wireless connection, guarantees the necessary simultaneity of measurements.

Self-Powered phase sequence measuring device. HT82 is a mobile device to display the phase sequence with 3 terminals in a generic three-phase system. The device provides an “R” indication in case of correct phase sequence or “L” indication in case of incorrect phase sequence.

TRMS three-phase voltage data logger; XL424 is a Data Logger capable of measuring and recording the true root mean square(TRMS) value of AC voltage up to 600V in three-phase 3-wire electric systems for different applications (evaluation of mains voltage, load unbalance, etc.).

HT4020; Professional clamp meter AC TRMS 400a with power measurement. TRMS. Ac current up to 400a. Active, reactive, apparent power. Active, reactive, apparent energy. Cosphi, frequency and phase sequence. Cat III.

Clamp meter with flexible clamp jaws AC 3000A The clamp is provided with innovative flexible current probe capable of reaching a maximum diameter of 110mm and allowing for an easy reading in any condition. The clamp is provided with a wide display with 3000 measuring spots, Data HOLD function and Backlight to allow for a simple reading even in poorly lit environments. The clamp is also provided with the auto power off function to preserve its own battery.

HT204 is a digital solar meter for measurements of solar irradiation up to 2000W/m2, which can be used as an inspection device, typically in photovoltaic installations.

HT9023 has been designed to measure AC, DC AC+DC current up to 1000A in TRMS reaching CAT IV 600V and CAT III 1000V in compliance with safety standard IEC/EN61010-1. The clamp also measures DC voltage up to 1500V, AC, AC+DC voltage up to 1000V, Active, Reactive and Apparent Power, Power Factor, Energy, voltage/current harmonic analysis up to the 25th with THD% calculation in balanced single-phase or three-phase systems. It is also possible to carry out the phase sequence test with 1-terminal. 

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.

I-V525w 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 1500V and 10A or 1000V and 15A. For measuring I-V Curve, I-V525w 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-V525w, 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.

MPP300 is an optional accessory which allows measuring and recording the main parameters which characterize single- and threephase, single. and multi-string photovoltaic systems (up to three MPPT). Provided with a practical rigid anti-shock case, thanks to its lightness and its reduced size is the ideal solution for on-site use. MPP300 interfaces with SOLAR300N and SOLAR I-V for its settings, to start/stop recording electric and environmental parameters and to allow for the download of the recorded values.
