A brand new concept in solar PV test instrumentation is making its debut at SPI this year that combines accurate I-V curve analysis with essential electrical testing for the fast and effective commissioning, safety and O&M diagnostic testing of all types of solar PV installations.
Using simple push button operation, the new multi-function PV210 from Seaward (booth W824) carries out all the electrical commissioning tests required by IEC 62446, including open circuit voltage, short circuit current, maximum power point voltage, current and power and insulation resistance. Alongside the electrical tests, the PV210 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 any further analysis or fault finding. The fill factor of PV systems can also be assessed.
Accurate visual comparisons of curve shapes can be used for the immediate identification of potential problems such as shading, defective cells or poor electrical connections. Data can also be exported instantly from the accompanying PVMobile app to the head office for further analysis and investigation. Special wireless Solarlink connectivity between the PV210 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.
Complete I-V curve and electrical test data can be stored in the PV210’s large onboard memory and downloaded to a PC in CSV format via USB connection for full traceability of system data and test records.
