AC overcurrent is an inverter fault that is reported when the AC output current goes above the inverter's upper current limit. In monitoring data, it appears as an inverter fault code for an instantaneous AC overcurrent, and the inverter stops feeding the grid. The inverter usually reconnects to the grid by itself once the grid is back to normal, so a single event often needs no action. If the fault keeps coming back, record how often it happens and contact the inverter manufacturer. A revenue meter may stop logging peak demand, maximum values and energy while its overcurrent elements are active, so meter records can leave out the event itself.

Reported as an inverter fault code (Sungrow code 007) when the AC output current goes above the inverter's upper current limit.
