Seaward has released a new diagnostic test device, the PV200/210 test equipment.
Combining IV curve analysis and electrical testing, the battery-powered multi-function PV200/210 with push-button operation performs all electrical commissioning tests required by IEC 62446. These include open circuit voltage, short circuit current, maximum power point voltage, current and power, and insulation resistance.
In addition to electrical testing, the instrument shall perform IV curve measurements according to IEC 61829 to determine if the measured curve deviates from the expected profile, highlighting the need for further analysis and fault finding. You can also The fill factor of the photovoltaic system can also be evaluated.
Instantly transfer measurement data from your test instrument using wireless connectivity (NFC) to the included PV mobile Android app for detailed analysis with high-definition color display of IV and power curves for individual PV modules or strings can be created. In this way, an accurate visual comparison of curve shapes can be used to quickly identify potential problems such as shading, defective cells, or poor electrical connections. Data can also be instantly exported to headquarters for further analysis and investigation.
A wireless connection between the PV200/210 and the Solar Survey 200R meter also allows you to view and measure real-time irradiance simultaneously with electrical testing. With the irradiance and temperature data transferred to PVMobile, the measured electrical data can be converted to STC and directly compared with the manufacturer’s published data stored in the PVMobile database. Complete IV curves and electrical test data can be stored in onboard memory and downloaded to a PC in CSV format via USB connection for full traceability of system data and test records.
When integrated with the optional SolarCert software program, downloaded data can be quickly and easily organized using a hierarchical tree structure showing strings, combiner boxes and inverters. In addition, professional inspection and test reports can be generated including IEC 62446 measurements and IV curve plots.
