Configuration Options

Because temperature has a significant impact on the performance of operational PV solar systems, PV module temperature is one of the most critical measurements to monitor and analyze.

Purpose-built to withstand the elements and accurately sense PV module temperature, our 0.2 C interchangeable 10K NTC Thermistor sensor ensures Class A measurements per IEC-61724-1:2017. The PVT1’s 4-wire cable configuration delivers accurate measurement regardless of cable length when used with our SymphoniePRO Data Logger and enables flexible positioning on PV arrays.

Each sensor comes with double-sided adhesive on its compact housing as well as a specially designed adhesive system to secure both sensor and cable in place for easy and repeatable installation as well as long-term performance.
