Wi-Fi Configuration via SEMS APP

WiFi Configuration via SEMS Portal App

suitable type：

• WiFi Box
• WiFi KIT
• WiFi/LAN KIT

Before using the SEMS app, ensure your phone is set up correctly: 

1. Turn OFF Mobile Data 

    Go to Settings → Mobile Data / Cellular Data → Turn Off 

This is important because mobile data can interfere with the direct Wi-Fi connection to the inverter. 

2. Turn ON Wi-Fi (WLAN) 

    Go to Settings → Wi-Fi / WLAN → Turn On 

3. Connect to the Inverter’s Wi-Fi

Look for a Wi-Fi network named:  Solar-WiFiXXXXXXXX 

(The last 8 characters are the final 8 digits of your inverter’s serial number.) 

Tap the network to connect. When prompted for a password, enter:12345678 

Note: Your phone will show “No internet connection” — this is normal because you are connecting directly to the inverter, not the internet.
