Is your Sungrow inverter no longer producing data? Let’s get that back for you with the PSW Energy Sungrow 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 Sungrow iSolarCloud.
Important: this post is pending an update. If you cannot reconnect your Sungrow Inverter and are a PSW Energy customer, please contact PSW Life Support in the meantime.

The following Sungrow inverter WiFi reconnect guide is applicable for all Sungrow WiFi enabled inverters which include the Sungrow SG#K-D, Sungrow SG#KTL-M and SG#K-20 Hybrid models.
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, there is a high chance your Sungrow inverter disconnected from your WiFi network. Your inverter is now trying to communicate through an IP address 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 system’s lifetime. Here is how to get your Sungrow inverter WiFi reconnected.
Note: If your inverter has disconnected from your WiFi network, this will not affect your solar energy system’s ability to produce energy. It will only prohibit communication with the Sungrow iSolarCloud server, allowing you to view your solar production information.
Required before initiating the sequence
- Physical access to your Sungrow inverter.
- A WiFi-enabled device such as a smartphone or tablet.
- Patience, the average reconnection time is 10mins.
Step 1: Connect device WiFi
Go to your Settings menu within your smartphone or tablet.
Select the inverter WiFi network named SG-******
Step 2: Login and configure
Once your smartphone or tablet has successfully connected to the inverter WFi network, open the Sungrow iSolarCloud Application.
Login to your iSolarCloud account.
PSW Customers: Your default username is your email address, and your default password is psw1111
When logged in, select the MORE tab in the bottom left corner of the page.
Select the WLAN CONFIGURATION tab.
Information will appear notifying you that you’ve successfully connected to the inverter. Select NEXT.
Step 3: Network setup
The final step is to connect your inverter to your home WLAN (Wireless Local Area Network). Select your WIFI NETWORK from the list and enter your password.
The symbol “” indicates a successful connection, click NEXT
Information indicating a successful connection to the home network will pop up. Your inverter is reconnected.
By the end of this process, you’re probably thinking, why isn’t there just a simple WPS button like many other WiFi-enabled appliances? We hear you! Unfortunately, many mainstream inverter manufacturers haven’t adopted such modern conveniences yet.

Every chance the inverter is too far away from the wifi

My error message is “Failed to set password. Please try again”. It says that after about a minute of the coms light flashing. I removed the wifi dongle and then re-installed it but that made no difference. The signal is four out of fivebars for the home wifo so it’s not a signal issue – it simply won’t accept the password. I suspect the issue is the new Telstra Smart Modem Gen 2 which insists on WiFi security like WSK or better which I don’t think the Sungrow dongle can be configured to provide. Also, how can I find out the MAC address of the dongle? I thought if I gave it a fixed IP address that might help.
