• Updating firmware via the user interface of the inverter.
• Updating the firmware via USB flash drive.
Updating firmware via the user interface
Requirement:
☐ An update file with the desired inverter firmware must be available. The update file is, for
example, available for download on the product page of the inverter at www.SMA-Solar.com.
Procedure:
1. Activate the user interface (see Section 5.1, page 19).
2. Log into the user interface (see Section 5.2, page 22).
