Download the right app for GoodWe
Use the app named in your Esena handover. These buttons open verified Apple App Store or Google Play listings.
Choose carefully: Recommended: SEMS+. Sign in with your existing GoodWe account so your station history remains available.
Turn off Mobile Data / Cellular Data completely. Leave Wi-Fi on, stand near the inverter and have the 2.4 GHz home Wi-Fi password ready. Check that the Wi-Fi/LAN module is securely fitted and the inverter is powered—do not remove the module.
- 01Open SEMS+ and tap Wi-Fi Configuration on the home or login screen.
- 02Tap Next, then select Go into WLAN setting interface. Your phone’s Wi-Fi settings will open.
- 03Connect to Solar-WiFiXXXXXXXX. The numbers match the end of your inverter serial number. Enter the hotspot password 12345678.
- 04If your phone says the Solar-WiFi network has No Internet, stay connected. This temporary connection is expected.
- 05Return to SEMS+ and tap Next. Select your home 2.4 GHz Wi-Fi network and carefully enter your home Wi-Fi password.
- 06Tap Set or Confirm, then tap OK when the configuration is complete. Allow about 60 seconds for the network settings to apply.
- 07Check the physical inverter. The orange Wi-Fi LED or blue COM light should change from flashing to a steady light. Then reconnect your phone to your normal home Wi-Fi and check SEMS+.
- 08If the station is still offline after up to 10 minutes, photograph the module label and lights and create a support ticket. Do not factory-reset, remove or replace the module.
ImportantThese are SEMS+ customer steps. Light colours can vary by inverter or communication module, so report the exact colour and flash pattern if the light does not become steady.
