SMA Solar Technology AG Archiving Data on a SD Card
11.6 Updating the Firmware
The firmware of the Sunny Island can be updated using the SD card. When the Sunny Island starts up
or when the SD card is inserted, the Sunny Island searches for special update files on the SD card.
If it finds files containing new firmware versions, it performs an update when the Sunny Island is in
standby mode.
Proceed as follows for a firmware update:
Take note of:
• You may only download firmware versions from www.SMA.de/en. Using
unauthorized firmware versions cancels the warranty.
• None of the already existing parameter settings are changed or erased during a
firmware update.
• New parameters are assumed with default values.
• If there is an update to firmware version greater or equal to 5 000, the battery
management is automatically reset. This means that some of the set parameters for
the battery management are lost.
• Do not activate the DC circuit breaker during the firmware update.
• Updating the firmware or single-phase systems takes approximately 5 minutes.
• Do not switch off the Sunny Island during the firmware update.
• Updates in systems with a master and slaves can take up to 20 minutes. A progress
bar is shown on the master display.
• The slave update starts approximately 5 minutes after the master update.
• An equalization charge is automatically initialized after the firmware update.
