The Voltage-Ear – An Anomaly in Photovoltaic Systems With Undersized Inverters

The Voltage-Ear – An Anomaly in Photovoltaic Systems With Undersized Inverters

This study presents a phenomenon in photovoltaic field installations we call voltage ear. PV installations exhibit the voltage ear under specific conditions where modules generate more power than the inverter can handle. When inverters exceed their power limit it results in inverter clipping, and th...
