8.28 Firmware Update

You can activate an automatic firmware update in the inverter or in the communication product.
If no automatic update is set for the inverter in the communication product (e.g.
SMA Data Manager, Cluster Controller, Sunny Portal) or via the user interface of the inverter, you
have the option of carrying out a manual firmware update.
You have the following options to update the firmware:
• Automatic Firmware Update (Recommended)
• Update the firmware with the existing update file via the user interface of the inverter.
• Update the firmware with the existing update file via USB flash drive.
• Search and install the firmware via the user interface of the inverter.

8.28.1 Activating Automatic Firmware Update

You can activate the automatic firmware update in the inverter or in the communication product.
If the automatic firmware update is activated in the inverter, the inverter searches for updates and
carries out the update.
If the automatic firmware update is activated in the communication product, the communication
product searches for updates for the inverter and carries out the update of the inverter. In this case,
the automatic firmware update is deactivated by default in the inverter. This prevents multiple
downloads of updates.
In this section we describe how to activate the automatic firmware update in the inverter. The
procedure for activating the automatic firmware update for detected devices in the communication
product can be found in the manual for the communication product.
The basic procedure for changing operating parameters is explained in another section (see
Section 8.14, page 77).
Procedure:
• In the parameter group Device > Update, select the Automatic Update parameter and set
to Yes.
