Operating manual
Remedy
• Check after about 5 minutes whether the parameter change
has been accepted. If necessary, repeat the parameter change.
• Ensure that parameters cannot be modified at the same time on
the user interface of the product and in Sunny Portal.
Remedy
• Contact your network administrator.
• Verify your entry.
Remedy
• 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.
• 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.
• 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.
