Fault Current of PV Inverters Under Grid-Connected Operation …

When grid-connected PV inverters "trip" during a fault, it means that they cease to energize the utility. PV inverters generally sense a fault occurrence by the associated voltage drop at its point of common coupling (PCC). According to IEEE Std 929–2000, the "trip time" should occur within the limits presented in Table 1.
