S2-WL-ST, S3-WIFI-ST, S4-WiFi-ST and S5-WiFi-ST, dataloggers

Welcome to the setup guide for your Solis Wi-Fi Dongle! This device allows you to easily connect your Solis inverter 

to your Wi-Fi network, enabling data monitoring through the SolisCloud app.

Follow the steps below to complete the setup quickly and easily. This guide is for the models S3-WiFi-ST, S2-WL-ST, S4-WiFi-ST, and S5-WiFi-ST.  

Step 1: Before You Begin

• Ensure you have your Wi-Fi network name and password.

• Your router should operate on 2.4GHz (only during configuration; 5GHz can be re-enabled afterward).

• Position your phone close to the inverter (within 1-2 meters).

• Install the SolisCloud app (optional but recommended).

Step 2: Turn Off Mobile Data

• iOS: Settings > Mobile > Mobile Data > Off

• Android: Settings > Connections > Data Usage > Mobile Data > Off

Step 3: Forget Your Home Wi-Fi

• Forget your home Wi-Fi connection (make sure you record your password before completing this step).
  (Go to Settings > Wi-Fi > Click on or > Click on Forget)

Step 4: Connect to the Solis Wi-Fi Dongle

• The Wi-Fi inverter dongle will show up as a Wi-Fi network (Solis_5A12********) in your available Wi-Fi list.
• The number after "Solis" will be the same as the serial number of your Wi-Fi dongle.
• See the example below -

IOS

Android 

Connect to Solis_5A12XXXXXXX 
Password: 123456789

NOTE:
The number shown here is just an example. You will have a different number that matches your Wi-Fi dongle's serial number. Once connected, it should say "No Internet Connection" or "Unsecured Network"

The Wi-Fi signal name may be D_5A12XXXXXXX

Step 5: Open Browser & Enter IP Address

• Open your internet browser (e.g., Safari or Chrome) and enter the IP address 10.10.100.254 in the in the URL bar (not Google search bar).
• Then press Go/Search.

IOS

Android

NOTE: depends on the firmware version you might have two scenarios to enter the IP  

1. On the old firmware with the default password 123456789
2. On the new firmware the user is required to set their own password, this password should be 6-15 digits and includes at least one number and at least one letter. (E.g. Solis1)
   

• Once you enter a New Password, the system will ask you to re-login.

Step 6: Log in

• You should get a screen prompt asking for your Username and Password. 

Enter Username: admin

Password entered in step 5: Solis1

Click Sign in.

Step 7: Select Your Wi-Fi Network

1. You will see a screen as shown below. From the top left corner, press Quick Set (second option). 
2. Press on "Search" button and look for your house Wi-Fi network.

Step 8: Enter Your Wi-Fi Password

• Select your Wi-Fi name and ensure that the RSSI (signal strength) is more than 30%.
  (Anything below 30% is not recommended.)
• Click OK once you have selected your network.

Step 9: Check Your SolisCloud App

• Enter your home Wi-Fi password.
• Click on the eye symbol to check the password before confirming.
• Click Save.
  (Do not fill in any other fields.)
• To obtain an IP automatically, it needs to be enabled

Note: After clicking Save, the stick will restart immediately. If the connection was successful, the wireless AP mode of the stick will be disabled. If not, you need to log in again and perform the configuration process again. 

STEP 10:

• Once you see the confirmation message, open your SolisCloud app and check your Datalogger Status.

NOTE:

• It takes about 10 seconds for the monitoring stick to connect to the network.
• If the green LED light turns solid, the setup was successful.
• If the green LED keeps flashing, the setup failed.

ALL DONE!

IMPORTANT:
If setup is completed but there is no update in SolisCloud after 5 minutes, please double-check the Wi-Fi password, reset the dongle, and repeat all steps.
