I-V Curves and PV Performance Verification
PVA-1000S PV Analyzer Kit is a 1000 Volt 30 Amp I-V curve tracer with built-in PV performance modeling and advanced wireless irradiance, temperature and tilt sensing. It provides unprecedented measurement throughput and accuracy and delivers deep insight into the performance of your arrays.
For each string, the PV Analyzer measures the I-V (current vs. voltage) and P-V (power vs. voltage) curves with a single button click. The measured results are compared to the expected performance, taking into account the irradiance and module cell temperature at the time of the I-V measurement. The I-V Unit communicates wirelessly to your Windows tablet or laptop (not included), enhancing safety and allowing freedom of movement during testing. Automated data analysis and reporting save you time.
The PV Analyzer is designed to work as hard as you do. High measurement throughput means it can measure 1 MW in less than 2 hours--even in hot environments where other curve tracers shut down. The rugged enclosure is moisture and dust resistant. The incident angle corrected SolSensor is able to make accurate irradiance readings in lower light conditions extending your working window.
I-V curve testing is the preferred method for commissioning, O&M, and troubleshooting of PV arrays because it provides the most complete performance measurement possible. Populations of curves can be analyzed quickly for outliers and data can be archived as a baseline for future reference if performance questions arise.
Measure strings up to 30 Amps. The high current rating can be useful for measuring multiple strings in parallel, for example when harnessing before the combiner box is employed. Please note, however, the maximum current for strings of high efficiency modules with ≥ 19% efficiency is 10 Amps.
