Step-by-step instructions for troubleshooting ABB 5-6kW inverter Wi-Fi connectivity.
On your phone, Go to wifi setting and search for inverter network (ABB or Fimer with the correct serial number).

Select the inverter network
Enter password (it's usually found on a sticker on the side of the inverter near the QR code). Password includes digits and hyphens. DO NOT omit the hyphens.

Open safari or chrome browser and enter: 192.168.117.1
Select manage router and go to dashboard.
You should always be near the inverter and stay on that browser while connecting.
If you open other browsers or app, it can’t be connected.

Once you are on the inverter home page, choose utica001 mode
key in password: utica001
Go to wifi connectivity icon (beside alarm icon) and select Wi-Fi.

Please check the wifi station. If you see the green light below Wi-fi Station, it means wifi-connected. (Please double check that the blue light is stable and not flashing on the inverter). This could take 1-3 minutes.
If not connected, open your hotspot network from your mobile data, and fill in the password. Choose DHCP in IP setting. Please wait for a while until it is connected.
