I-V Curve Tracers

  • - 1500

The smallest, lightest, and fastest capacitive I-V tracer up to 1,500V on the market. In 2021, it was the first tracer in the world to incorporate up to two albedo reference cells for measuring bifacial modules. With an input range of 1,500V and 35A, it can measure any combination of photovoltaic modules and strings.

Drastically reduce the time spent on O&M, commissioning, and quality control with Entec Solar’s E-1500 I-V curve tracer, all while maintaining excellent measurement accuracy and robustness for measuring very high-efficiency modules.
