Technical Description
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 security copy of the existing parameter lists (see section 11.3 ”Saving and Loading
Parameters” (page 96)).
2. Download the current version of the firmware 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's slot.
☑ The update is carried out.
6. Press <Enter> and keep pressed.
☑ The Sunny Island starts and the update is complete.
Duration of the firmware update
The update for 1‑phase systems takes approximately 5 minutes.
Depending on the system configuration with more than one Sunny Island, updating the
software might 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 disconnector to the ”On”
position.
Note:
• 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 firmware version greater or equal to 5.000 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 ensures the changes become
effective. After the reset, the master device remains in standby mode.
