Before reconnecting, make sure your GoodWe inverter is powered on.

Check these two indicators:

• Orange LED on the inverter: If the orange light flashes twice, the inverter is not connected to Wi-Fi.
• Blue LED on the Wi-Fi dongle: If there is no solid blue light, the inverter is not connected to the internet.If either indicator shows a disconnection, continue with the steps below.

1. Check your Wi-Fi signal strength
‍
Stand next to your GoodWe inverter with your phone and make sure your home Wi-Fi network appears in the available list.

If the Wi-Fi signal in this area is weak or not visible, install a Wi-Fi extender or use a wired Ethernet connection.
‍

‍Open your Goodwe SEMS Portal app on your smartphone or tablet and select  WI-FI CONFIGURATION in the bottom right-hand corner of the login screen.

Make sure your Goodwe inverteris powered ON and select next.

‍

If the inverter does not connect after setting the password, repeat the steps and re-enter your Wi-Fi password carefully.

Make sure you are selecting the correct home network.

Ensure the Wi-Fi signal is strong where the inverter is installed.

If connection issues persist, restart the inverter and repeat the process.
