Firmware Update - SMA SUNNY ISLAND 4548-US Operating Manual

11 Data Storage on SD Memory Card

11.6 Firmware Update

The firmware of the Sunny Island can be updated via the SD memory card. Upon startup or when the
SD memory card is inserted, the Sunny Island searches for special update files on the SD memory
card. If it finds files containing new firmware versions, it performs an update when the Sunny Island is
in standby mode.
Duration of the firmware update
The update for single-phase systems takes approximately five minutes.
For system configurations with more than one Sunny Island, the software update can take up to
20 minutes.
A status bar shows the progress of the update. Leave the SD memory card in the Sunny Island
until the update is finished. During the update process, leave the DC switch to the "On" position.
