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.

Goodwe inverter WiFi reconnect guide.

The following Goodwe inverter WiFi reconnect guide is applicable for all Goodwe WiFi enabled inverters which include the Goodwe D-NS, Smart DT and ET Hybrid models.

For ease of reference the Goodwe buttons will be referred to as 1, 2, 3, 4 from left to right.

Step 1.

To complete the reconnection of your inverter, you’ll need access to the inverter and a WiFi-enabled device such as your smartphone or tablet. 

Open your Goodwe SEMS Portal app and click on WIFI CONFIGURATION in the bottom right-hand corner. Make sure your Goodwe inverter is POWERED ON and click next.  Click on the “GO INTO WLAN SETTING INTERFACE” button, a pop up will appear with all the information you need to connect to your inverter network.

Step 2.

Open up the WIFI SETTINGS on your device and find your solar inverter network “Solar-WiFi########” and enter the password “12345678”.

Once you’ve connected to the inverter network, reopen the Goodwe SEMS app. Click NEXT again and select “the desired wireless network for the inverter” (your home WiFi network) and click CONNECTION.

Enter in your home WiFi network password and click next. You’ve successfully configured your inverter and the power light or WiFi light will now be solid (no flashing).

    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?

    I have the same issue as well. I have 2 inverters, one has wifi light flashing as ready to go the other has a different series of flashes indicating it cant contact the server. I have deleted and reinstalled app. I have tried resetting the wifi units on the inverters by pushing and holding the little black button in the inverter, also turned off both inverters and restarted. I can connect to the Solar wifi via iphone, then it won’t let me go to the next step, ie connect to home internet. Any help would be appreciated.

    My Goodwee Inverter reports OFFLINE. I can ping the Solar-WiFi. I have turned off the INVERTER and turned back on, using correct procedure. The yellow led blinks 4 time every 1.6 seconds. I rebooted the Solar-WiFi and even the router. Still reports OFFLINE. It is true it is overcast day but reported online between 7:10 am and 8:00 pm. It then dropped to zero. Did same yesterday and was zero from 8:00 am to end of day. Can you advise? Please.
