4 Error Messages Relating to the Inverter
4.1 Device Errors
4.2 Display Errors
4.3 Errors during/after Updates
Inverters with graphic display show these disturbances via event number 73XX, all others via the light chaser (green, red
and yellow LEDs blink one after the other).
Analysis/Test Data/Measured Values
Th
e causes for device errors cannot always be clearly assigned. It is
important to know why and when an error occurs in order to consider
possible causes in the system. This information will help us with the cause
analysis.
Read out the fault memory.
Note the correct event
number:
• When does the error occur? Contact SMA Service.
– regularly/frequently or just once?
• Does the error disappear after a
restart or does it persist?
• In other inverters in the system as well?
• Since when has the error been occurring?
Analysis/Test Data/Measured Values
For analyzing display errors, photos of the display and the mounting
location of the inverter are of particular importance.
Differences in the contrast of the displays can generally occur. These
differences are partly manufacturer-related or influenced by ambient
conditions such as temperature.
Take photos.
Contact SMA Service.
Analysis/Test Data/Measured Values
For manual updates: Note down the initial
version:
• Was the update executed in accordance with the installation
manual?
• Was the SD memory card set up with the correct folders/files? Note down the target
version:
• Were the update requirements met during the update (irradiation
stable and sufficient for grid feed-in (min. 1,000 W))?
Reason for update?
If the update requirements have not been met, the inverter can buffer the
files and complete the update at a later time. It makes sense however, to
only perform updates when the operating conditions are stable, i.e. when
there is sufficient DC power and a connection to the AC grid so that the
inverter can feed in.
Check the display and/or data logger for
the version display for FW package and HP
after completing the update
