SMA CLUSTER CONTROLLER - Manual (Page 77)

14 Update
14.1 Automatic Update (Recommended)
14.1.1 Setting the Automatic Update for Cluster Controller
In the automatic update of the Cluster Controller, only update files for the Cluster Controller are
taken into account. The update files are downloaded via the Internet from the SMA Update Portal.
The Cluster Controller checks once a day whether a new update is available. If a new update is
available, the Cluster Controller downloads the update. The update process starts automatically the
following night at 11 p.m. Settings already made for the Cluster Controller and the system data are
retained after the update. If an automatic update process for the Cluster Controller is interrupted,
e.g. due to a power outage, the Cluster Controller restarts the update process at the next possible
time.
Requirement:
☐ The Cluster Controller must be connected to the Internet.

1. Select the Cluster Controller in the system tree and select the menu Settings in the device
menu.

14.1.2 Setting the Automatic Update for Connected SMA Devices
No update is performed for inverters with communication errors ( )
No update is performed for inverters that are not connected to the Cluster Controller as a
result of a communication error.
• Using the inverter event log, determine the cause for the communication error and rectify
the error so that the inverter is no longer displayed with the symbol in the system tree.
Sufficient DC input voltage is required for update
For some inverters, updates are only possible above a specific DC input voltage. Depending
on the time of day, the weather, or the condition of the PV modules (e.g. affected by pollution
or covered with snow), the DC input voltage may be too low for the update. The affected
inverters do not feed in during the update. This can result in temporary yield losses.
