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&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…
