Updating the Firmware

If no automatic update is set in the communication product (e.g. SMA Data Manager or Sunny Home Manager) or in
Sunny Portal, you have the option of carrying out a manual firmware update.
Duration of firmware update
For systems with 1 battery inverter, the firmware update takes about 15 minutes. For systems with 3 or more
battery inverters, the firmware update takes about 30 minutes. Premature intervention via the user interface leads
to the termination of the firmware update.
• After starting the firmware update, wait until the system-specific duration of the firmware update has expired.
Firmware update for single-cluster and multicluster systems
In each cluster, the master carries out the firmware update on the slaves. In a multicluster system, each master
requires its own firmware update.
• In a single-cluster system, carry out the firmware update on the master.
• In a multicluster system, carry out the firmware update on each master in any order.
