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: Active the Dongle
With your Sungrow inverter, there is a little dongle down the bottom. Inside the dongle, there is a button. First thing you do is click this button three times. As soon as you do that you’re good to go.
Step 2: Access iSolarCloud
Open up iSolarCloud on your phone.
Go to the bottom right-hand corner where it says “Support.”
Click that and then go to “Local Access.
Step 3: Identity Verification
A prompt will appear instructing you to scan a QR code.
Locate the QR code on the WiFi stick of your Sungrow inverter and scan it.
A popup will show up, saying “iSolarCloud” Wants to Join Wi-Fi Network “SG-###########”? Hit “Join“ on that.
It comes up with the field “IDENTITY VERIFICATION” where it says “user.”
Enter the password “pw1111” and press the “VERIFICATION.”
Step 4: Network Configuration
You will be directed to the local plant screen. Go to the bottom right-hand corner where it says “More.”
Click that and then go to “WLAN Configuration.”
It’ll show all the available WiFi networks in the area.
Select your home network, enter your WiFi password, and press “CONFIRM.”
You should get a green tick, which means you’ve successfully connected your Sungro inverter to your home network. You should also notice that the Sungrow WiFi dongle has a blue LED on the WLAN port.
Amazing work! Your Sungrow inverter is now back on the internet.
