Sigenergy SigenStor Wi-Fi Reconnect
Sigenergy SigenStor
(For Sigenergy inverter and battery system – including SigenStor 5-in-1 units)
1. Check your WiFi signal strength
Stand next to your SigenStor system and check your phone to confirm your home WiFi network appears in the list.
If the WiFi signal is weak or not visible, install a WiFi extender or use a wired Ethernet connection.
The SigenStor only supports 2.4 GHz WiFi — it cannot connect to 5 GHz networks.
2. Restart your Sigenergy inverter
Restarting the system resets communication and enables the built-in WiFi hotspot needed for reconnection.
Turn off the AC switch
This switch is located inside the Sigenergy Gateway.
Find the switch labelled Inverter Supply and flip it up to OFF.
Turn off the DC switch
The DC switch is inside the small cover on the left side of the inverter.
Lift the cover upward to remove it.
Inside, turn the DC switch to OFF.
Wait a few minutes until the inverter fully shuts down.
Then restart in reverse order:
- Turn the DC switch ON
- Turn the AC / Inverter Supply switch ON
Allow several minutes for the system to power up.
This restart will automatically enable the inverter’s WiFi hotspot for reconnection.
3. Open the mySigen app
On your phone, launch the mySigen app.
If you do not have it installed, download it from the App Store or Google Play.
4. Go to Settings
Tap Settings in the bottom-right corner of the app.
5. Open Network Configuration
Under More Settings, tap Connectivity.
Tap Next to begin the setup and follow the on-screen instructions.
6. Scan the QR code on the inverter
The app will open your phone’s camera.
Scan the QR code located inside the inverter cover beside the DC switch.
7. Choose to connect via hotspot
When prompted, select ‘No, I want to connect device hotspot’.
This option allows the app to connect directly to the inverter’s WiFi hotspot.
7. Connect to the inverter hotspot
Tap Next, then Connect.
Your phone will automatically join the Sigenergy hotspot (usually named Sigen_xxxxxx).
If a password is requested, enter 12345678.
Once connected, the app will search for available WiFi networks.
Select your home WiFi network, enter your password (case-sensitive), and tap Join.
8. Verify the connection
A tick mark will appear next to your WiFi network once the connection is complete.
Tap Finished to close the setup.
The inverter will now connect to your home WiFi and resume sending live data to the mySigen app.
9. Troubleshooting tips
Double-check your WiFi password for accuracy.
Ensure your router’s 2.4 GHz network is enabled (SigenStor cannot use 5 GHz).
If the hotspot does not appear, repeat Step 2 to restart the system.
If issues persist, contact your installer or Sigenergy Technical Support.
