the digital signal processor
460
(DSP) is working out of toler-
ance
461 DSP data memory error
462 Error during DC feed monitor-
ing routine

475 tion fault (connection between
solar module and ground)

lay is switched off
Functional incompatibility (one
or more PC boards in the in-
480
verter are not compatible with
481
each other, e.g. after a PC
board has been replaced)
482 Start-up incomplete

string out of limits
485 CAN transmit buffer is full
489 Permanent overvoltage on in-
termediate circuit capacitor
(five 479 status codes in a row)
Status codes – Class 5 status codes do not generally interfere with feeding energy into the grid, but can
Class 5 cause restrictions. These status codes are displayed until they are acknowledged by
pressing a key (however, the inverter continues to operate normally in the background).
Behaviour
The inverter is not feeding any
energy into the grid.
The inverter is not feeding any
energy into the grid.
The inverter will automatically
attempt to connect again and,
if possible, will resume feeding
energy into the grid.
The inverter is not feeding any
energy into the grid.
on MPP2
The inverter is not feeding any
energy into the grid.
The inverter is not feeding any
energy into the grid.
Remedy
Notify a Fronius-trained ser-
vice technician.
If this status code keeps recur-
ring, contact your system engi-
neer.
If the status code is displayed
all the time: Notify a Fronius-
trained service technician.
Update inverter firmware;
If the status code is displayed
all the time: Notify a Fronius-
trained service technician.
Perform AC reset (switch auto-
matic circuit breaker off and on
again), complete start-up
Check the MPP settings;
If the status code is displayed
all the time: Notify a Fronius-
trained service technician.
