High DC Input Voltage
The yellow LED is on for 5 seconds, remains off for 3 seconds and then blinks 4 times. The code is
repeated 3 times. If the condition remains the code will continue to be sent.
The inverter has detected a DC input voltage that is too high for safe operation.
WARNING!
If opening the Sunny Boy is required, do so only after disconnecting all sources of power
and waiting at least 5 minutes.
WARNING!
Disconnect the PV array from the Sunny Boy immediately. High DC input voltage can
permanently damage the inverter. Have the input source checked by a qualified technician.
WARNING!
Always test the DC voltage at the DC disconnect switch before energizing the Sunny Boy.
