📶 Growatt Wi-Fi Reconnection Guide

If your Growatt inverter shows as offline in the ShinePhone app, it usually means the Wi-Fi needs reconnecting (common after changing broadband or router).

Follow the steps below to get your system back online.

Option 1 – 🔗 Standard Mode (Recommended if Wi-Fi signal is strong)

1. Open ShinePhone app on your phone.
2. Tap My Device List `
3. Tap Datalogger (Shine WiFi-X)
4. Tap  Configure.
5. Choose Standard Mode.
6. Enter your home Wi-Fi SSID and password (must be 2.4 GHz Wi-Fi).
7. Wait for confirmation → the inverter will attempt to connect.
8. Return to the home screen and confirm the device shows Online.

Option 2 – 📲 Hotspot Mode (Use if Standard Mode fails)

Hotspot Mode uses a direct connection to the inverter to push your Wi-Fi details.

1. On the inverter, press the Wi-Fi dongle button until the red light flashes — this enables hotspot mode.

   On your phone, go to Wi-Fi settings and connect to the Growatt hotspot (named AP_xxxx   ).

   • Default password: 12345678  
2. Open the ShinePhone app → My device list → tap on datalogger → edit.
3. Choose Hotspot Mode.
4. Select your home Wi-Fi SSID, enter your password, then confirm.
5. The inverter will connect to your router.
6. Return to the ShinePhone home screen → confirm status shows Online.

⚠️ Important Notes

• Growatt inverters only support 2.4 GHz Wi-Fi (not 5 GHz).
• If you’ve changed broadband, try renaming your new Wi-Fi SSID and password to match the old router so all devices reconnect automatically.

• For detailed instructions, see the official manual:
