Did you get a new internet service provider or change your Wi-Fi password? Follow these instructions to get your SMA solar system back online!
To connect your SMA inverter to a new or existing internet connection you’ll need a smartphone or laptop somewhat close to the inverter. If you scan for WiFi networks nearby, you’ll see a WiFi network called “SMAXXXXXXXX”. It’s password is very long, 15-16 characters, and can be found on a label on the lower right side of the inverter that says WPA2-PSK (circled below in orange).
Tip: Once you’re connected to the inverter’s WiFi, this helpful video shows each step listed below: https://youtu.be/_T4n_lBZnSM
We recommend using the Google Chrome web browser and open an “Incognito Window” to login to your inverter. Go to the web address 192.168.12.3, and don’t be alarmed by a security screen that appears, looking like this (it’s completely normal):
Click “advanced“, and “proceed to 192.168.12.3“. You’ll come to a login screen for your Sunny Boy inverter. Use the user group “User“, and the password provided to you by Ecotech Solar service (contact us if you haven’t!)
Now you can go to the menu icon (three lines at the top right), and go to “device parameters”, and click “edit parameters” (or “edit all”) at the top of the screen. Scroll down under ”system communication”>”WLAN”>”Security”, and here you can enter the network name and password. Don’t forget to hit “Save all” when you’re done!
If you want confirmation that the settings have been received, wait about 10 minutes, and walk over to you inverter, and notice the small display. Give the screen a firm knock, like you would knock on a front door, and you’ll notice the display illuminate. Each time you knock the screen, it takes you to a new set of information. After about 5 knocks, you’ll see a display that says “SSID” and “RSSI“. This should now show your network name, and signal strength of 0-100%.
