4.2.2 Display Messages for Plant Disturbances
If an operational failure occurs, the display immediately switches to "Disturbance" and the
background illumination lights up. In this case the inverter stops feeding into the grid. The following
illustrations give examples of possible failure scenarios.
• The cause of the failure is displayed for 5 seconds
in the second line of the display.
• If the failure is triggered by a measured value, then
the value measured at the time of going into fault is
displayed. If a further measurement is possible, the
current value is displayed in the second line.
• After another 5 seconds the normal operating data
appear. If the fault is still present, the fault display
cycle starts over again. An overview of the status
and error messages can be found in
Section 6 "Measurement Channels and
Messages" (page 28) of this documentation.
• "Error ROM" indicates that the inverter has
recognized an error in the EEPROM firmware.
Please contact SMA Solar Technology to have the
error corrected.
4.2.3 Rapid Blinking of Background Illumination
DC Overvoltage
If an excessive DC input voltage is present at the Sunny
Boy / Sunny Mini Central, this is indicated by rapid
blinking of the background illumination and the message
shown on the right.
NOTICE!
DC input voltage too high. Destruction of the inverter.
• Please contact your installer, who will immediately disconnect the PV generator from
the inverter and check the DC voltage, as described in the inverter installation guide.
