Likely causes.

Ask yourself the following questions;

  • Was there a blackout or a power outage recently?
  • Has the modem been switched off for any reason recently?
  • Have you recently changed to the NBN?
  • Has the modem been changed or upgraded?
  • Has the solar system been switched off recently?
  • Has an electrician been working on the property?

If you answered yes to any of the above, then there is a high chance your Huawei inverter has disconnected from your WiFi network. In a nutshell, your inverter is now trying to communicate through an IP address which is no longer available from your modem.

It’s important you know the steps to reconnect any WiFi based device as IP addresses will continue to change over the systems lifetime. Here is how to get your Huawei inverter WiFi reconnected. 

IMPORTANT: If your inverter has disconnected from your WiFi network, this will not affect your solar energy systems ability to produce energy. It will only prohibit  the communication to the Huawei FusionSolar cloud server which allows you the view your solar production information.
