1 min Reading time If your inverter communicates with your router via Wi-Fi, the Wi-Fi password is also set in the inverter. If you switch to a new router (for example, when changing providers) or if you have changed your Wi-Fi password, you will usually need to reconfigure the inverter to maintain communication. This step-by-step guide explains how to do this. This guide applies only to SMA inverters of the Sunny Boy and Sunny TriPower types that are equipped with Wi-Fi.

<p>You will return to he inverter home screen. If everything went well, the communication with the new router—and thus with the internet and Sunny Portal—should now be established. You can now close the browser on your smartphone, tablet, or PC and reconnect your device to your own Wi-Fi network. Once the connection is successful, you will have a steady <a href="[[~2007]]">blue LED</a> on your inverter.
