Why does the generator or grid not reconnect, although the cutoff limit (for voltage or frequency) is now no longer being breached on my SMA Sunny Island 5048 Inverter?
The Sunny Island connects with a hysteresis, meaning the connection value is slightly below or above the disconnection value. These limiting values are predefined.
What to do if my SMA Sunny Island 5048 QCG does not run?
Switch off the Sunny Island and restart it.
What is required if the SMA Sunny Island is continuously switched off after Low Battery Mode (LBM) when restarting the device?
If the Sunny Island is continuously switched off after Low Battery Mode (LBM) when restarting the device, start the generator manually, if required (e.g.: Run1h). Also, consider the time for warming up: 5 minutes without charging current in BatProtMode can cause the device to change to standby mode.
What to do if QCG does not run once on SMA Sunny Island 5048?
Switch off the Sunny Island 5048 and switch it back on.
What to do if my SMA Sunny Island 5048 battery cell can no longer be used?
Remove the unusable cell from your battery bank. Start the Sunny Island and change the battery voltage in the QCG under 'New Battery'.
Why can't I change the parameters on my SMA Sunny Island 5048?
There are several reasons why you might not be able to change the parameters on your SMA Inverter. First, ensure that you have entered the installer password correctly and are in "Installer Level". You can only read data values in the "100-Meters" (measuring data) menu or the "300-Diagnose" (Diagnosis) menu. Also, some parameters can only be changed in standby mode or in the QCG.
What to do if a battery cell can no longer be used in my SMA Sunny Island 5048 system?
If a battery cell is unusable, remove it from your battery bank. Then, start the Sunny Island 5048 and change the battery voltage in the QCG under "New Battery".
Why does the Sunny Island SMA not connect to the running generator?
The Sunny Island may fail to connect to the running generator for several reasons. First, check the generator's fuse. Second, verify that the power fed back into the generator during the permissible time hasn't been exceeded, indicated by a "!" display. If exceeded, the generator connection is blocked; acknowledge it by setting the "540.02 GnAck" parameter to Ackn. Third, if the generator control relay (GnReq) is open, ensure the generator is set to autostart via the "234.07 GnStrMod" parameter. Finally, if a GenMan is used, check the return signal, as the generator can only be manually started with GenMan.
Why is my SMA Sunny Island staying on even though I switched the DC circuit breaker to Off?
Your Sunny Island may still be powered by the AC side. To resolve this, switch off all AC consumers and disconnect them from the Sunny Island.
Why does my SMA Sunny Island connect to the running generator only for a short time?
Your Sunny Island might connect to the running generator for only a short time if the limits for the maximum permissible AC voltage or the minimum permissible frequency of the generator are too strict. These parameters are located in the menu "233# Generator Control". Adjust the voltage and/or frequency limiting values, while being mindful of the technical data for your generator.
