Firmware Update
If no automatic update is set for the inverter in the communication product (e.g. SMA Data Manager, Cluster Controller, Sunny Portal) or via the user interface of the inverter, you have the option of carrying out a manual firmware update.
Depending on the battery used, the firmware update of the inverter also updates the battery.
You have the following options to update the firmware:
Automatic Firmware Update (Recommended)
-
Update the firmware with the existing update file via the user interface of the inverter.
-
Update the firmware with the existing update file via USB flash drive.
-
Search and install the firmware via the user interface of the inverter.
Faulty firmware update due to disconnecting the inverter from the utility grid or when the battery is disconnected or discharged.
The inverter must be connected to the utility grid and the battery must be switched on during the firmware update. The state of charge must be at least 5%. The battery-backup and secure power supply operation must be disabled. This ensures a proper firmware update.
- Ensure that the battery is switched on and the state of charge is above 5%.
- Do not disconnect the inverter from the utility grid during the firmware update.
- Do not enable secure power supply operation during the firmware update.
- Do not use the black-start button during the firmware update.
