Grid Failure
The yellow LED is on for 5 seconds, out for 3 seconds and then blinks twice. The
code is repeated 3 times. If the condition remains, the code will continue to be sent.
This code can be caused by any of the following conditions:
• Low Grid Voltage (<Vac Min)
• High Grid Voltage (>Vac Max)
• Low Grid Frequency (< fac Min)
• High Grid Frequency (>fac Max)
• Significant change in grid frequency
Check the condition of the grid by varifying service to other customers or to other
equipment. Also inspect the AC disconnect between the Sunny Boy and the grid.
CAUTION:Have the grid connection to the Sunny Boy
checked only by a qualified electrician.
WARNING:If troubleshooting methods require that
you open the Sunny Boy inverter, do so only after
disconnecting all sources of power to the Sunny
Boy.
