9.2 Performing a Subdevice Update
9.2.1 Information
You can update the firmware on the devices of your PV plant via the Sunny WebBox. For the following
devices, updating the firmware via the Sunny WebBox is possible:
• all SMA inverters with integrated Bluetooth
• SMA Bluetooth Piggy-Back/SMA Bluetooth Piggy-Back Plus from firmware version 02.00.00.R.
• SMA Bluetooth Piggy-Back Off-Grid from firmware version 01.00.00.R
• SMA Bluetooth Repeater
• SMA Power Injector with Bluetooth
The device update can be performed online via the Internet or locally via the SD card. Settings already present
for the Sunny WebBox and data for the PV plant are retained following the update process. To ensure that the
devices of your PV plant always have the latest firmware installed, the automatic device update via the Internet is
recommended.
Firmware updates for inverters of the type SB x000TL-20 with a firmware version
older than 2.06 are only possible using an SD card
• Perform firmware updates of these inverters using an SD card (see technical
description "Firmware Update with SD Card" at www.SMA-Solar.com).
NOTICE
Yield losses possible!
For some inverters, device updates are only possible from a specific DC input voltage.
The inverters in question do not feed energy during a device update. This can result in
temporary yield losses.
Do not change the update source during the update process
If you change between the update sources "Storage card" and "Update portal" during the
update, the firmware update will not take place.
No update is performed for devices with a padlock symbol ( )!
Devices that have no connection to the Sunny WebBox due to a lack of access rights
(marked with a padlock symbol ( ) in the plant tree) receive no update.
If you do not have the necessary access rights, change the password of the device
concerned to the password of the plant (see Sunny WebBox user manual).
Sufficient DC input voltage is required to update the devices!
In some inverters, a device update is only possible from a certain DC input voltage. The DC
input voltage can be too low for a device update, depending on the time of the day,
weather or the condition of the PV modules (e.g. covered with snow or leaves).
Do not disconnect the Sunny WebBox from the electricity grid during the update
process.
