Problem
Cause and corrective measures
The firmware of a connected
SMA product was not up-
dated during a firmware up-
date via USB flash drive.
The firmware version downloaded is not the latest or is not
suitable for the SMA product.
• The firmware version must be later than the firmware version
installed on the SMA product. Ensure that you have
downloaded the correct firmware version for your SMA
product and update the firmware again.
The DC input voltage is not sufficient for a firmware update.
• With older inverters, a firmware update is only possible above
a certain DC input voltage. Depending on the time of day, the
weather, and the condition of the PV modules (e.g. affected by
pollution or covered with snow), the DC input voltage may be
too low for a firmware update. Ensure that there is sufficient DC
voltage present and update the firmware again.
The transmission quality in the local network is not sufficient.
• Errors can occur during data transmission if the transmission
quality in the local network is too low. Check the network status
of your local network and, if necessary, contact your network
administrator.
No data are displayed on
the user interface of the
Data Manager.
The buffer capacitor of the Data Manager's real-time clock
might have discharged due to being without voltage supply
for a longer time period.
• Ensure that the Data Manager has access to a time server on
the Internet or in the local network to obtain a current time.
