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 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 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 to do if I can't change the parameters on my SMA Inverter?
If you cannot change the parameters on your SMA Inverter, verify that you have entered the installer password correctly and are in "Installer Level". Also, confirm that you are not in the "100-Meters" or "300-Diagnose" menu, as data values can only be read there. Some parameters can only be changed in standby mode or in the QCG. Stop the Sunny Island to enter standby mode; however, be aware that this will cause a dropout in the stand-alone grid system.
Why is it not possible to set any combinations of voltage and frequency limits on my SMA Sunny Island 5048 Inverter?
The possible ranges for voltage and frequency of the Sunny Island allow the combination of special frequencies and voltages that result in transformer saturation and are therefore not permitted.
Why is it that one (or more) extension clusters remain in standby, although the main cluster is operating properly on my SMA Inverter?
If one or more extension clusters remain in standby while the main cluster operates correctly, check the communication cable between the master devices. If the cable is disconnected, the main master cannot forward the "Start" command to the extension master, causing the devices to remain in standby.
Why is the Multicluster system not supplying full power output on my SMA Sunny Island 5048 Inverter?
The Multicluster system might not be supplying full power output if an extension cluster's slave has failed. Although the system continues to operate, the output on the phase of the failed device will be lower.
Why is it that shortly after startup, the slave switches to standby with the failure message F117, but the master continues to operate on my SMA Sunny Island 5048 Inverter?
Shortly after startup, if the slave switches to standby with the failure message F117 while the master continues to operate, it may be due to the phases within the cluster, or from the cluster to the Multicluster Box, being connected the wrong way around. This causes a permanent short-circuit in the cluster, which the slave reports to the master.
Why is it that high outputs are being transferred back and forth between the clusters in the cluster network of my SMA Inverter?
If high outputs are being transferred back and forth between the clusters in the cluster network, the nominal frequencies and voltages are likely defined differently. Correct this by adjusting the appropriate parameters.
What to do if my SMA Inverter battery is discharging even though the generator is running?
If the generator is running but the battery is still discharging, it could be because the power produced by the generator isn't reaching the Sunny Island. Check the voltage and frequency values. Alternatively, the consumer power might exceed the generator power, so check for any error messages to identify the cause.
