Huawei Inverter Wifi Reconnect Guide.

Is your Huawei inverter no longer producing data? Let’s get that back for you with the PSW Energy Huawei 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 FusionSolar app.

INSIDE!

Huawei inverter WiFi reconnect guide.

The following guide is applicable for all Huawei wifi-enabled solar inverters, including the SUN2000L, SUN2000-L1, SUN2000-M0 and SUN2000-M1.

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.

Requirements before initiating sequence.
  1. Physical access to your Huawei inverter.
  2. A WiFi-enabled device such as a smartphone or tablet.
  3. The Huawei FusionSolar app installed on your smartphone or tablet.
  4. Patience, the average reconnection time is 10mins.
  5. PSW Tip: Tea, Coffee or a refreshing beverage of your choice. You’re welcome in advance 😉

The easiest way to reconnect is by scanning the QR code at the bottom of the label to connect to the inverter’s wifi once you have opened the FusionSolar app. However, if this is not an option on your model, please follow these steps:

Step 1.

Open the FusionSolar app on your smartphone or tablet device. 

Select the WiFi tab in the top left -hand corner, then the second option “TAP TO GO TO SYSTEM SETTINGS”

Step 3.

Ensure that the DHCP option is enabled and that the domain name is au1.fusionsolar.huawei.com for SUN2000 single-phase inverters and SUN2000L-KTL inverters installed prior to December 2019 or to sg5.fusionsolar.huawei.com for all SUN2000-KTL-MO three-phase inverters and ALL inverter models installed by us from December 2019 onwards.
