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
3 (75.0%)2280AC UNDER VOLT: The AC line voltage has dropped below its minimum threshold
1 (25.0%)2030AC OVER VOLT: The AC line voltage has exceeded its maximum threshold
