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

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 Huawei 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 systems lifetime. Here is how to get your Huawei 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 to the Huawei FusionSolar cloud server, allowing you to view your solar production information.
Indicators on the dongle
- Flashing Red: The initial state of the configuration
- Solid Blue: Dongle is launching hotspot, waiting to use AP mode method
- Flashing Blue: Dongle has been connected to router
- Solid Green: Failed connection, network not 2.4ghz / wrong Wi-Fi name or password in AP method / Wi-Fi signal is too weak
- Flashing Green: Dongle is connected to router, but router has no internet
Required before initiating the sequence
- Physical access to your Growatt inverter.
- A WiFi-enabled device such as a smartphone or tablet.
- Patience, the average reconnection time is 10mins.
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 ShinePhone app. However, if this is not an option on your model, please follow these steps:
Step 1: Open the ShinePhone App
Open the ShinePhone app on your phone.
Click on the plus (+) icon in the top right corner of your screen.
Select “Datalogger list.”
Click on the datalogger that displays and select “Configure datalogger.”
Choose “Hotspot Mode.”
Locate the dongle on the underside of the inverter. Look for the LED light labeled “KEY.”
If the LED is flashing red, you need to switch it to hotspot mode.
Use a small screwdriver or safety pin to press the button inside the cutout once.
The LED light will change to solid blue, indicating hotspot mode.
Note: If the dongle LED is already solid blue, it is already in hotspot mode, and you can skip this step.
Step 2: Connect device WiFi
Step 3: Connect to the Hotspot
On your phone, connect to the inverter’s hotspot.
Select “Go to Set.”
Choose WiFi and select the Datalogger (the name will start with JP).
Enter the password when prompted. The default password is 12345678.
Step 4: Final Configuration in ShinePhone App
Once connected, return to the ShinePhone app.
Ensure the SN and hotspot name have the same value, then click “Next step.”
Your home WiFi network will display. Click “Configure immediately.”
Allow several minutes for the datalogger to pair with the network.
Congratulations! Your Growatt inverter is now back online. You can verify the connection by navigating back to the ShinePhone app’s home screen, where the datalogger will now show as “Online.”
