  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.

  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.
