Seaward has launched a brand new diagnostic testing gadget — the PV200/210 check instrument.
Combining I-V curve evaluation with electrical testing and utilizing a push button operation, the battery-operated multi-function PV200/210 undertakes all {the electrical} commissioning assessments required by IEC 62446. These embrace open circuit voltage, quick circuit present, most energy level voltage, present and energy, and insulation resistance.
Alongside {the electrical} assessments, the instrument also can carry out I-V curve measurements in accordance with IEC 61829 to find out if the measured curve deviates from the anticipated profile, highlighting the necessity for any additional evaluation or fault discovering. The fill issue of PV methods can be assessed.
For detailed evaluation, measured knowledge might be transferred immediately from the check instrument to an accompanying PV cellular android app utilizing wi-fi connectivity (NFC) to create high-definition colour shows of the I-V and energy curves for particular person PV modules or strings. On this approach, the correct visible comparability of curve shapes can be utilized for the rapid identification of potential issues akin to shading, faulty cells or poor electrical connections. Information can be exported immediately to go workplace for additional evaluation and investigation.
Wi-fi connectivity between the PV200/210 and the Photo voltaic Survey 200R meter additionally permits real-time irradiance to be displayed and measured similtaneously electrical testing is being undertaken. Irradiance and temperature knowledge transferred to PVMobile can be utilized to transform measured electrical knowledge to STC for direct comparability with producers’ revealed knowledge saved within the PVMobile database. Full I-V curve and electrical check knowledge might be saved within the onboard reminiscence and downloaded to a PC in CSV format by way of USB connection for full traceability of system knowledge and check information.
When built-in with the optionally available SolarCert software program program, downloaded knowledge might be rapidly and simply organized utilizing a layered tree construction exhibiting string, combiner field and inverter. As well as, skilled inspection and check experiences might be produced, together with IEC 62446 measurements and I-V curve plots.
