9.1 Performing Own Update for Sunny WebBox
9.1.1 Information
You have the option of updating the Sunny WebBox firmware. You can perform the firmware update
via the Internet or locally via the SD card. The existing settings of the Sunny WebBox and data from
the PV plant remain available after the update procedure. In order to keep the Sunny WebBox
firmware up to date at all times, automatic firmware updates via the Internet are recommended.
The update procedure is indicated by the flashing orange "SYSTEM" LED and occasionally by a red
light chaser across all LEDs. The firmware update is complete when the "SYSTEM" LED glows green.
An update procedure can take up to a maximum of 20 minutes.
