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:
1. Create a backup copy of the existing parameter lists (see Section 11.3 "Saving and Loading
Parameters", page 97).
2. Download the latest firmware version from the Internet at www.SMA-America.com.
3. Copy the "UPDATE.BIN" file onto the SD card.
4. Set the master device to standby.
5. Insert the SD card in the master slot.
☑ The update is carried out.
6. Press and hold <ENTER>.
☑ The Sunny Island starts. The update is carried out.
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 card in the Sunny Island until the
update is finished. During the update process, leave the DC switch to the "On" position.
Observe the following:
• • You may only download firmware versions from www.SMA-America.com. 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 the firmware version greater or equal to 6,000, the battery
management is automatically reset. All set parameters are lost.
• Do not activate the DC circuit breaker during the firmware update.
• Do not switch off the Sunny Island during the firmware update.
Reset after a successful update
After the update has been successfully completed, a reset is enforced in order for the changes
to become effective. After the reset, the master device remains in standby mode.
