“Error ROM“ indicates, that the Windy Boy 5000 /
6000 has recognized a fault in the Firmware
EEPROM. Contact SMA to correct the fault.
Special display in the case of excessive
DC input voltage
If an excessive DC input voltage is present on the
Windy Boy 5000 / 6000, then this is indicated by
rapid blinking of the background illumination and a
corresponding message.
Immediately disconnect the DC input of the Windy Boy 5000 /
6000. The presence of excessive input voltage can lead to
irreparable damage! Make sure that the input voltage never
exceeds 600 V.
When the Windy Boy 5000 / 6000 receives an excessive DC input voltage, it
automatically disconnects from the mains supply and no longer feeds power
into the grid. When the Windy Boy 5000 / 6000 is in operation, you must
always first disconnect the AC voltage (mains supply) and only then should you
disconnect the DC voltage from the Windy Boy 5000 / 6000.
Before placing the device back into operation, the input voltage must be
checked before reconnecting the DC voltage to the Windy Boy 5000 / 6000!
Since the Windy Boy 5000 / 6000 is identical to the Sunny Mini Central, apart
from the mode of operation, the display of the Windy Boy 5000 / 6000 shows
"PV" (Photovoltaic) as its input source.
