10.10.100.254 Login: Setting Up a Solar Inverter WiFi Stick

If you are trying to reach 10.10.100.254, you are almost certainly setting up a solar inverter WiFi stick, also called a data logger, not a normal router. This address is the local setup page for the small WiFi module that plugs into a solar inverter and sends its power-generation data to a monitoring app. Brands using it include Solarman, Solis, Sofar, and others. This guide explains how to log in and connect the stick to your home Wi-Fi.

What 10.10.100.254 Actually Is

A solar inverter WiFi stick is a small dongle that plugs into the inverter’s communication port and connects it to the internet, so you can monitor your solar system in an app like SolarMan or SolisCloud. The stick broadcasts its own temporary Wi-Fi hotspot, and 10.10.100.254 is the address you use to configure it.

This is different from a home router. You are not changing your main Wi-Fi settings here, you are telling the solar stick how to join your existing Wi-Fi network so it can report data. So if you arrived expecting your router’s admin page, this is not it, and your router uses a different address such as 192.168.1.1.

How to Log In to 10.10.100.254

1. Make sure the inverter is powered on and the WiFi stick’s power light is lit.
2. Connect to the stick’s hotspot. On your phone or computer, open your Wi-Fi settings and connect to the hotspot broadcast by the stick. Its network name usually looks like AP_ followed by numbers, or something like SOLIS_XXXX or WiFi_XXXX. The stick’s serial number often matches the numbers in the network name. If a Wi-Fi password is required, it is typically printed on the stick’s label, and some units use 12345678.
3. Turn off mobile data on your phone, so it does not switch away from the stick’s hotspot while you work.
4. Open a browser and type http://10.10.100.254 in the address bar, not the search box. Take care with the digits, since 10.10.100.254 is easy to mistype.
5. Enter the username and password.

Username and Password

Device	Username	Password
Most WiFi sticks	admin	admin
Some models	admin	12345678
Newer firmware	admin	(you create one at setup)

The most common login is admin for both the username and password. Some sticks use 12345678 as the password instead. Newer firmware often requires you to create your own password during setup, sometimes with a rule such as 6 to 15 characters including at least one letter and one number. The correct details are usually printed on the label on the stick, which is the definitive source.

How to Connect the Stick to Your Wi-Fi

Once logged in, the goal is to point the stick at your home network.

1. Look for a Wizard, Quick Set, or Network Configuration option in the dashboard.
2. The stick scans for nearby Wi-Fi networks. Select your home network from the list.
3. Enter your home Wi-Fi password carefully.
4. Keep “Obtain IP automatically” enabled, and click Save.
5. The stick reboots and connects to your Wi-Fi. Wait about a minute.

An important requirement: the stick almost always needs a 2.4 GHz Wi-Fi network, not 5 GHz. If your router combines both bands under one name, you may need to separate them or temporarily use the 2.4 GHz network during setup. Once the stick’s network light shows a solid connection, it is online, and you can view your data in the monitoring app.

What to Do If 10.10.100.254 Will Not Load

You are not connected to the stick’s hotspot. Confirm your phone or computer is joined to the stick’s AP_ network, not your home Wi-Fi or mobile data. Turn off cellular data to stop it switching away.

Check the address for typos. Enter 10.10.100.254 exactly, in the address bar, with no www, no .com, and the http prefix only if needed. Confusing it with 10.10.10.254 is a common mistake.

The stick’s hotspot is not appearing. Make sure the inverter is on and the stick is seated firmly in its port. Power-cycling the inverter can bring the hotspot back.

The default login is rejected. Check the label for a unique password, or try 12345678. On newer firmware, use the password you created during setup. If it was changed and lost, reset the stick.

It will not connect to your Wi-Fi. Confirm you are using a 2.4 GHz network and that the Wi-Fi password is correct. Both are common causes of failed connections.

How to Reset a WiFi Stick

Most sticks have a small reset button or pinhole. With the stick powered, press and hold it for around 10 seconds until it restarts, which restores the default settings and login. You then run the setup again from 10.10.100.254. Because the stick is mounted on the inverter, often in an awkward spot, take care reaching the button.

Wrapping Up

10.10.100.254 is the setup page for a solar inverter WiFi stick, not a home router, so if you landed here, you are connecting your solar monitoring to the internet rather than changing your Wi-Fi. Connect to the stick’s AP_ hotspot, open 10.10.100.254, log in with admin and admin or the label credentials, and use the Wizard to join your home Wi-Fi, remembering to use a 2.4 GHz network. Once the stick’s status light goes solid, your solar data will appear in the monitoring app. If it is actually your router you are looking for, see our guide on how to find your router’s IP address instead.
