  Several factors can cause this. The signal between the inverter and the wireless router might be too weak. Try the following: * Modify the position of the wireless antenna, the inverter, or the router. * Ensure the inverter isn't near obstacles that could affect communication, such as metal cages or walls, reinforced concrete walls, or electromagnetic fields. * Move the router closer to the inverter. * Install a wireless signal repeater to extend the network and connect the inverter to the repeater. Also, if the wireless network requires a username and password for navigation (like a public network), the inverter cannot connect to it. Use an alternative wireless network in this case.

  This issue can occur for several reasons. One reason is that the wireless network is set to be hidden. The Inverter cannot connect to a hidden network. Set the wireless network to be visible, then identify and connect the Inverter to the wireless network as normal. Another reason could be a weak signal between the inverter and the wireless router. To resolve this, modify the position of the wireless antenna, the inverter, or the router. Also, make sure that the inverter has not been installed near obstacles which could affect the communication with the wireless router, and move the router as close as possible to the inverter or install a wireless signal repeater.

Why is my ABB Inverter having alternating difficulties in the local connection to the internal webserver?
- C
  Christopher WhiteAug 27, 2025
  This could be due to a few reasons. First, the inverter might not be correctly powered. Access to the internal webserver is only possible when the inverter has power. Second, the wireless connection signal between your device and the router or the Inverter may not be strong enough or could be affected by obstacles. Ensure the signal is sufficiently strong and free from interference from metal cages or walls, reinforced concrete walls, or strong electromagnetic fields.

  There are a couple of things to check. First, the wireless board of the inverter could be damaged. In this case, request a service intervention to check that the inverter wireless board is working correctly. Second, wrong Inverter Date/Time settings can cause this issue. Check if Date/Time has correctly set on the inverter and correct it if necessary.
