Why can't I change parameters on my SMA Inverter Sunny Island?
- E
  Erika GonzalezAug 21, 2025
  If you can't change parameters on your SMA Inverter Sunny Island, there might be a few reasons. First, ensure the installer password has been entered correctly and that you are in 'Installer Level'. If needed, recalculate and re-enter the password. Second, you might be in the '100-Meters' (Measuring data) or '300-Diagnose' (Diagnosis) menu, where data values are read-only. Finally, some parameters can only be changed in standby mode or in the QCG. Stop the Sunny Island as described in section 10.1.2 'Stopping'.

What to do if my SMA Sunny Island 2012 Inverter Sunny Island connects to the running generator only for a short time?
- W
  Wesley RobbinsAug 25, 2025
  If your Sunny Island inverter connects to the running generator only briefly, the limits set for the maximum permissible AC voltage or the minimum permissible frequency of the generator might be too strict. You should change the voltage and/or frequency limits, making sure to observe the technical data for your generator.

Why is the display of my SMA Sunny Island 2012 Inverter Sunny Remote Control 1 dark?
- J
  Jessica RiddleAug 26, 2025
  If the display of your Sunny Remote Control 1 is dark and shows nothing, start by checking the communication cable. Ensure it is properly connected and that both RJ45 plugs are securely snapped into their sockets. Also, inspect the BatFuse (external DC fuse) to see if it has been activated. If so, the Sunny Island is disconnected from the battery and has switched off; replace the DC fuses. Finally, verify if the BatFuse is functional. If it is, the device might have switched off to protect the batteries from deep discharge. To restart the Sunny Island, refer to section 10.1.5 'Restarting the System after Automatic Shutdown'.

Why is my SMA Sunny Island 2012 battery discharging even though the generator is running?
- M
  Michele GreeneAug 27, 2025
  If your battery is discharging even when the generator is running with SMA Inverter, it could be due to two reasons. First, the power produced by the generator might not be reaching the Sunny Island. Check the voltage and frequency values. Second, the energy produced by the generator might not be sufficient to supply all the consumers, meaning both the generator and the battery are supplying power.
