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
261,376 (98.2%)10INTERNAL ERROR: IGBT Desat or control logic fault. An occurrence of this fault requires that the unit be completely powered down to reset it.
4,360 (1.6%)2280AC UNDER VOLT: The AC line voltage has dropped below its minimum threshold
149 (0.1%)1000DC OVER VOLT 1: The DC Bus voltage has exceeded its maximum threshold
110 (0.0%)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.
76 (0.0%)2500TURBINE PHASE: Indicates that there is a problem with one or more of the turbine input phases. Bad connection, missing phase.
36 (0.0%)2030AC OVER VOLT: The AC line voltage has exceeded its maximum threshold
33 (0.0%)4000OVER TEMP: The internal high temperature threshold has been exceeded
21 (0.0%)3050OVER CURRENT: The DC Boost phase of the converter module has exceeded its maximum current threshold
6 (0.0%)8100AC UNDER FREQ: The frequency of the utility grid voltage went out of range. The lower range threshold was crossed
