Goodwe Inverter Wifi Reconnect Guide.

Is your Goodwe inverter no longer producing data? Let’s get that back for you with the PSW Energy Goodwe Inverter WiFi Reconnect guide. The great news is that this is often only ever a minor issue. Chances are the solar energy system is still producing power,  you simply can’t see this information being logged anymore through the Goodwe SEMS Portal.

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 Goodwe 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 Goodwe 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 Goodwe SEMS Portal cloud server which allows you the view your solar production information.

    Is there a way to set the inverter or wifi modem to auto reconect (e.g wps) or something without having to go through this procedure every time we have a power or internet outage ?

      The Goodwe should auto-reconnect every time. Potentially the issue exists within the modem your Goodwe is connected to as the modem may be changing the IP address each time there is a power or internet outage?
