Setting Up the Logger for WiFi with Cellular Backup

1. Connect the Logger:

   • Plug the logger into the inverter and ensure the inverter is powered on (with at least DC power).

2. Connect to the Logger’s WiFi Network:

   • Open your phone’s Wi-Fi settings and search for new networks.
   • Look for a network named "Solis_XXXXXXXXXX", where "XXXXXXXX" is the serial number of the logger.
   • If the network doesn’t appear, press and hold the Reset button for 10 seconds until both the NET and COM lights start flashing simultaneously.
   • Connect to this network.

3. Access the Logger's Settings:

   • Open a browser on your phone and enter 10.10.100.254 in the address bar.
   • Log in using "admin" as the username and "123456789" as the password.

4. Select Wi-Fi Mode:

   • Go to the Advanced tab, select Wi-Fi Only Working Mode, and tap Save.
   • The logger will restart. Wait a minute, then reconnect to the Solis_XXXXXXXXXX network.
   • Refresh the browser page.

5. Connect to Your Wi-Fi Network:

   • Go to the Quick Set tab and tap Search in the top-left corner.
   • Select your local 2.4GHz Wi-Fi network (Note: 5GHz networks are not supported).
   • Enter the Wi-Fi password (double-check for accuracy) and tap Save. You can tap the icon next to the password field to view it before saving.

6. Set Up Dual Connectivity:

   • Return to the Advanced tab and select 4G + Wi-Fi Working Mode, then tap Save.
   • The logger will now prioritize Wi-Fi, but if the connection is lost, it will automatically switch to the cellular network. Once Wi-Fi is restored, it will switch back.

7. Verify the Connection:

   • The Solis_XXXXXXXXXX network should disappear.
   • The NETlight will indicate the connection status:
     • Flashing green: Connecting to Wi-Fi.
     • Solid green: Successfully connected to Wi-Fi.
     • Flashing blue: Connecting to cellular.
     • Solid blue: Successfully connected to cellular.

8. Add the Logger to SolisCloud:

   • Log in to SolisCloud and go to your plant.
   • Tap the three dots in the top-right corner and select Add Device.
   • Use the scanner to scan the QR code on the logger. If scanning doesn’t work, place your hand behind the logger to help focus the scanner, or enter the serial number manually.
   • Go to the Device tab, then the Data Logger tab. The logger should now appear with information about its last reported status.

Setting Up the Logger for Cellular Only (No Wi-Fi Available)

1. Connect to the Logger's Wi-Fi Network:

   • Look for the network "Solis_XXXXXXXXXX". If it doesn't appear, press and hold the Reset button for 10 seconds. Wait for the NET and COM lights to flash, then check again.

2. Access the Logger's Settings:

   • Open a browser and enter 10.10.100.254 in the address bar.

3. Select Cellular Only Mode:

   • Go to the Advanced tab and select 4G Only Working Mode, then tap Save.
   • The NET light will flash blue for a few minutes before turning solid.

4. Verify the Connection:

   • A solid blue NET light indicates successful cellular communication.
   • If the NET light keeps flashing and never turns solid, the cellular signal is too weak. In this case, Wi-Fi should be used, or the logger may need to be replaced with a LAN-capable one.
