NOV-IV1500 String I-V Curve Tracer (1500 V / 20 A)
Portable I-V curve tracer for 1500 V PV strings. Gives full I-V and P-V curves with wireless irradiance and temperature sensing, and converts results to STC on site.
The NOV-IV1500 measures the real-world performance of PV modules and strings up to 1500 V under natural sunlight. A wireless irradiance and temperature probe (up to 100 m) records site conditions at the same moment as each sweep, and the instrument converts results to STC so they can be compared directly with the module datasheet. It is a dependable everyday tool for installers, EPCs and O&M teams who need fast, repeatable string checks.
