HT Instruments I-V600 – Advanced Multifunction I-V Curve Tracer

• Designed for maintenance and troubleshooting of photovoltaic systems
• I-V curve tracing of modules and strings up to 1500V and 40A
• Measurement of front-side and rear-side solar radiation for mono- and bi-facial module testing, even high-efficiency
• Measurement of open-circuit voltage and short-circuit current Voc/Isc
• Database of PV module performance

The HT Instruments I-V600 is an advanced multifunction instrument for I-V curve measurements up to 1500V and 40A. It is equipped with a user updatable database of modules allowing the measured data to be compared to the nominal values as provided by the manufacturer of the module/string under test to return a clear OK/NOT OK response. The included SOLAR-03 remote unit has a communication range of up to 100m (in free field). The logging function ensures tracing of the I-V curve in instances where communication was impossible due to obstacles such as floor, concrete structures, etc.

The I-V600 traces the I-V curve of mono-facial and bi-facial modules according to IEC technical specification TS 60904-1-2. In addition to the front-side radiation, I-V600 measures the back-side radiation by two different sensors (to consider the rear side irradiance non-uniformity).

The I-V600 drives up to 3 solar radiation reference cells and automatically recognizes the calibration parameters of the reference cells connected, eliminating the high risk of misconfiguration due to the number of parameters to be set.

Equipped with the patented BMS (Battery Management System), the I-V600 recharges its own batteries by recovering the power absorbed while tracing the I-V curve. With the I-V600 it is possible to reach the PV field with fully flat batteries, start the measuring campaign, and end it with fully charged batteries. Additional features include reversing graphics to properly read the display even while hanging the instrument upside down to the module rails, Wi-Fi connection to smartphones and tablets, and the microSD card slot to expand the memory.
