What does it mean if the SMA Controller status is flashing yellow?
If the status is flashing yellow, an update of the Cluster Controller or the connected devices is currently taking place.
What to do if the correct number of connected inverters isn't displayed on my SMA Network Hardware?
If the correct number of connected inverters isn't showing on the display, wait six minutes and check again. Also, ensure all inverters are in operation. Verify that the patch cables connecting the inverters are correctly connected, paying attention to the inverter or Speedwire/Webconnect interface installation manual. Make sure the inverter patch cable directly connected to the Cluster Controller is connected to network terminal X9 or X10. Finally, check for defective network components, patch cables, or plug connectors.
How to fix SMA Network Hardware when the login page doesn't open and the status LED flashes red?
If the login page doesn't open and the status LED flashes red, disconnect the Cluster Controller from the voltage supply and then reconnect it. Keep in mind that this action may result in a loss of plant data.
How to fix SMA Network Hardware login page if it does not open?
If the login page is not opening, make sure the three-pole plug for the voltage supply is connected to terminal X1 of the Cluster Controller. Also, ensure the voltage supply is correctly connected. If the voltage supply is correctly connected, consider replacing the top-hat rail power supply unit. Additionally, adjust the firewall settings to allow the required connection. Try selecting the External communication display view to find out the current IP address of the Cluster Controller and then call up the IP address via the Internet browser.
What to do if SMA Network Hardware voltage supply is reverse-connected or defective?
If the voltage supply is reverse-connected, ensure that it is correctly connected. If the voltage supply is correctly connected, then replace the top-hat rail power supply unit.
Why is the SMA Controller power glowing?
If the power is glowing, the voltage supply is too low. Ensure that the connected voltage supply is sufficient.
What to do if the login page does not open on SMA CLUSTER Controller because a firewall is blocking the connection?
If the login page doesn't open because a firewall is blocking the connection, adjust the firewall settings to allow the required connection.
Why is the SMA Controller status glowing red?
If the status is glowing red, communication with all devices is disturbed. There is a problem in the LAN. Ensure that the network cables are correctly connected. Check whether the network components, network cables or connectors are defective or damaged and replace them if necessary. Check whether the network settings of the individual network components are correct and adapt the network settings if required. Restart the Cluster Controller if required. Disconnect the Cluster Controller from the voltage supply and reconnect it to the voltage supply. If required, assign a fixed IP address for the Cluster Controller.
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.
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.
