The firmware of a connected SMA product was not updated during a firmware update

Cause	Remedy
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.
