A brand new concept in solar PV test instrumentation combines accurate I-V curve analysis with essential electrical testing for the fast and effective commissioning, O and M and diagnostic testing of all types of solar PV installations.
Using simple push button operation, the new multi-function PV200 from Seaward (PV210 in USA) carries out all the electrical tests required by IEC 62446, including open circuit voltage, short circuit current, maximum power point voltage, current and power, and insulation resistance.
Uniquely, alongside the electrical tests, the PV200 also performs I-V curve measurements in accordance with IEC 61829 to determine if the measured curve deviates from the expected profile, highlighting the need for further analysis or fault finding. The fill factor can also be assessed.
For full detailed analysis, measured data can be transferred instantly from the test instrument to an accompanying PVMobile Android App using wireless NFC connectivity to create high definition colour displays of the I-V and power curves for individual PV modules or strings.
In this way, the accurate visual comparison of curve shapes can be used for the immediate identification of common problems such as shading, defective cells or poor electrical connections.
Data can also be sent instantly and globally from the test site using the PVMobile app allowing data to be quickly available anywhere, for reference or further analysis and investigation if required.
Special wireless Solarlink connectivity between the PV200 and the Solar Survey 200R meter also enables real-time irradiance to be displayed and measured at the same time as electrical testing is being undertaken. Irradiance and temperature data transferred to PVMobile can be used to convert measured electrical data to STC for direct comparison with manufacturers' published data stored in the PVMobile database.
Complete I-V curve and electrical test data can be stored in the PV200's large onboard memory and downloaded to a PC in CSV format via USB connection for full traceability of system data and test records.
When used with the optional SolarCert Elements 2 software program, downloaded data can be quickly and easily organised using a layered tree structure showing string, combiner box and inverter. In addition, professional inspection and test reports can be produced, including IEC 62446 measurements and I-V curve plots.
The lightweight and battery powered PV200 is available in a range of kit options to meet your testing requirements.
