Fluke has released the SMFT-1000, a multifunction tester with I-V curve tracing. This all-in-one PV system test solution meets the IEC 62446-1 standard for Category 1 and 2 tests.

It measures open-circuit voltage (VOC) at the PV module/string up to 1000V DC and short-circuit (ISC) current measurement at the PV module/string up to 20A DC.

On-location I-V curve results compare manufacturer I-V curve data to measured data on the analyser screen.

To perform precise I-V curve measurements, real-time irradiance and temperature data are needed. The included IRR2-BT irradiance meter wirelessly connects to the SMFT-1000 to communicate data in real-time, providing the most accurate I-V curve measurements possible. If the wireless connection is interrupted for any reason, the IRR2-BT will continue recording data for up to 17 hours which can later be matched to tests taken with the SMFT-1000.

Data can be managed with TruTest solar software. A convenient setting in the SMFT-1000 lets users record observations directly into memory where the information can be downloaded later and incorporated into the project report.
