How to reconnect the GoodWe System to Wi-Fi

Before You Start

  • Stand near your powered-on inverter.

  • Confirm your home Wi-Fi is active and have your network password ready.

  • Ensure the updated SEMS Portal app is installed on your phone and logged in with your inverter linked.

Step-by-Step Connection Instructions

  1. Open Wi-Fi Configuration: Launch the SEMS Portal app. Tap Wi-Fi configuration on the login screen, or tap the Wi-Fi icon at the bottom of the main dashboard screen.

  2. Confirm Status: Tap Next. If prompted, tap I am aware of that to acknowledge the setup process.

  3. Connect to Solar Hotspot: Tap Go to WLAN setting interface to open your phone’s Wi-Fi settings. Select the network named Solar-WiFi (followed by numbers). Enter the password 12345678 and tap Connect. (Note: A "No Internet Available" prompt on your phone is completely normal).

  4. Enter Home Wi-Fi Credentials: Return to the SEMS Portal app and tap Next. Select your home Wi-Fi network from the dropdown list and enter your Wi-Fi password. Leave DHCP toggled ON, tap Set, and allow up to one minute for configuration.

  5. Reconnect & Verify: Tap OK when the success confirmation appears. Switch your phone's Wi-Fi connection back to your home network. Reopen the SEMS Portal app—your live data will reappear on the dashboard within a few minutes.
