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: Disconnect the PV array from the SB3800U
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 SB3800U.
