Real-time waveforms of neutral currents under varying irradiance levels (600–1000 W/m2) with a fixed non-linear load—(a) neutral current waveforms under balanced PCC voltage condition; (b) neutral current waveforms under unbalanced PCC voltage condition. CH1: Phase ‘a’ PCC voltage (400 V/div); CH2: source/grid neutral current waveform (10A/div); CH3: VSC neutral current waveform (1A/div); CH4: load neutral current waveform (1A/div).
