1000V/15A I-V Curve Tracer


The I-V400w is an I-V curve tracer which is compatible with HTANALYSIS™. I-V Curve Tracer (1000V/15A) can be used for troubleshooting and maintenance of photovoltaic systems.

Furthermore, using 1000V/15A I-V Curve Tracer; you may carry out the field detection of I-V Curve. In fact, the I-V Curve is one of the main characteristics parameters of both strings of modules and a single module for PV installations up until 1000 V and 15 A.

To illustrate, I-V Curve Tracer manages an internal database of modules (can be updated by the user at any time) to be able to measure the I-V Curve.

Moreover, the comparison between the rated values and the measured data; immediately let you evaluate if the module or the string fulfills the efficiency of the parameters which are declared by the manufacturer.

Also, you may measure the I-V curve by decentralizing measurement of temperature and irradiation; using the using the SOLAR02 which comes as an optional remote unit; and the radio frequency (RF) connection which comes with the master unit.

In addition, the display at the end of the I-V curve indicates the compliance with the specifications which the panel manufacturer has declared.

Equally important, the HT Instruments 1000V/15A I-V Curve Tracer offers important advantages and features that distinguish the quality product.
