Fault Frequency

This table shows the percentages and occurances of faults. A fault is when the inverter is in fault mode (system state is 11).

N Occurances Fault Code Fault Description
763 (97.0%)4000OVER TEMP: The internal high temperature threshold has been exceeded
24 (3.0%)8000AC OVER FREQ: The frequency of the utility grid voltage went out of range. The upper range threshold was crossed, or a ROCOF fault occurred.
