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 happens if the card inserted is not FAT16 formatted in my SMA Sunny Island 5048?
If the inserted card is not FAT16 formatted, the Sunny Island displays the message "Incomp".
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.
Why is the deactivation defined by the SOC in case of a full or equalization charge and generator start in the second time zone on my SMA Inverter?
The equalization charge has a higher priority than silent time.
What can I do when the QCG does not run on my SMA Inverter?
If the QCG does not run, switch off the Sunny Island and then restart it.
What do I do when a battery cell can no longer be used in my SMA Sunny Island 5048 Inverter system?
If a battery cell is unusable, remove it from your battery bank. Then, start the Sunny Island and change the battery voltage in the QCG under "New Battery".
What to do if "MMC operation failed" appears on the display of my SMA Sunny Island 5048?
If the message "MMC operation failed" appears on the display, it indicates an issue with an action performed using the SD card. Check the card on your PC/laptop. If necessary, use a new SD card.
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.
