What to do if the SMA Cluster Controller does not send any data to the external FTP server?
If the Cluster Controller isn't sending data to the external FTP server, ensure that there is enough storage space available on the FTP server. Also, ensure that the login data for the FTP server are correct and that the "Append" function is activated in the FTP server.
Why is an incorrect total number of connected inverters shown on the user interface or the display of my SMA Controller?
An incorrect total number of connected inverters might be displayed because communication with at least one inverter is disturbed. Either the Cluster Controller has not yet registered with one or more inverters, or the connection to one or more inverters has been interrupted. Wait six minutes and check again whether the correct number of all connected inverters is displayed. Ensure that the inverters are in operation. Ensure that the network cables that connect the inverters with one another are correctly connected. Ensure that the network cable of the inverter connected directly to the Cluster Controller is connected to network port X9 or X10 of the Cluster Controller. Ensure that no network components, network cables or connectors are defective.
What to do if the SMA Cluster Controller does not send any data to Sunny Portal?
If the Cluster Controller isn't sending data to Sunny Portal, it might be due to incorrectly configured data transmission. If the Cluster Controller is not yet registered in Sunny Portal, register it. Also check the settings for Sunny Portal and test the connection to Sunny Portal.
Why does the login page not open for my SMA Network Hardware?
The login page might not open due to several reasons. First, ensure the patch cable is correctly connected to the Cluster Controller. Then, check for any defective or damaged network components, patch cables, or plug connectors and replace them if necessary. Also, verify the network settings of all network components and adjust them if required. As an additional step, you can restart the Cluster Controller by disconnecting it from the voltage supply and reconnecting it. Note that this can lead to loss of plant data.
What to do if the login page does not open on SMA Controller and there is a problem in the LAN?
If the login page doesn't open and there is a problem in the LAN, ensure that the network cables are correctly connected to the Cluster Controller. Check whether the network components, network cables or connectors are defective or damaged and replace them if needed. Also, verify the network settings of the individual network components and adapt them if required. As a last resort, restart the Cluster Controller by disconnecting it from the voltage supply and reconnecting it. Note that this can lead to loss of system data.
Why aren't the expected binary values for the digital signal source showing on my SMA Network Hardware display?
If the expected binary values for the digital signal source are not showing on the display, ensure that the digital signal source is correctly connected.
Why aren't measured values for the temperature sensor showing on my SMA Network Hardware display?
If no measured values are displayed for the connected temperature sensor, ensure that the temperature sensor is correctly connected.
What to do if login to the user interface has failed on SMA Network Hardware?
If login to the user interface has failed, wait for 15 minutes, then log in with the correct plant password.
What to do if there's no current signal from the analogue signal source or sensor on my SMA Network Hardware display?
If there's no current signal showing for the analogue signal source or the sensor, ensure that the analogue signal source and the sensor are correctly connected.
How to connect SMA Network Hardware Cluster Controller to the voltage supply?
Ensure that the three-pole plug for the voltage supply is connected to terminal X1 of the Cluster Controller.
