For Sigenergy inverter and battery system – in any combination of inverter plus modules.

1. Check your Wi-Fi signal strength

Stand next to your SigenStor system and check your phone to confirm your home Wi-Fi network appears in the list.

• If the Wi-Fi signal is weak or not visible, install a Wi-Fi extender or use a wired Ethernet connection

2. Restart your Sigenergy inverter

Restarting the system resets communication and enables the built-in Wi-Fi hotspot needed for reconnection.

Turn off the AC supply — the switch location differs depending on whether you have backup functionality.

• Backup systems (Gateway installed): Find the switch labelled INV1 and/or INV2 inside the Sigenergy Gateway and flip it OFF. In some cases there may be an additional main switch for the battery inverter supply inside the gateway — this can be turned off instead
  
  

  

• No backup system: Turn the AC supply OFF using the main switch or inverter AC isolator inside the main switchboard

Turn off the DC switch. Lift the small cover on the left side of the inverter upward to remove it, then 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 will automatically enable the inverter’s Wi-Fi hotspot

3. Open the mySigen app

On your phone, launch the mySigen app.

• If you don’t 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, then 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 on the right side of the inverter, next to the serial number.

• You will need to remove the cover to access the QR code

7. Choose to connect via hotspot

When prompted, select No, I want to connect device hotspot.

• This allows the app to connect directly to the inverter’s Wi-Fi hotspot

8. 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 Wi-Fi networks
• Select your home Wi-Fi network, enter your password (case-sensitive), and tap Join

9. Verify the connection

A tick mark will appear next to your Wi-Fi network once the connection is complete.

• Tap Finished to close the setup
• The inverter will now connect to your home Wi-Fi and resume sending live data to the mySigen app

10. Troubleshooting

• Double-check your Wi-Fi password for accuracy — it’s case-sensitive
• 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
