HOW TO RECONNECT YOUR INVERTER TO WIFI

HOW TO RECONNECT YOUR INVERTER TO WIFI

Wifi is not covered under installation warranty with any solar system as it is a third party communication.

From time to time wifi may drop out, which will show on your app as a communications fault.

Your solar normally working fine.

First step is to have a look at your inverter and see if it has green lights or an audible alarm with a red flashing light.

If the inverter is showing green lights and working fine, the issue is with your home wifi.

One of 3 things:

  • Your 2.4g signal is weak – try moving your router closer to the inverter.
  • You have upgraded your wifi and your inverter – like computers TV etc, needs to be reconfigured to your new wifi.
  • you have added a new router and it has a new wifi username and password, so inverter needs to be upgraded as well.

Something noteworthy…

If you do change your internet service you will need to split your wifi 6g,5g,2.4g so different devices continue to work. Also – it is a very good idea to set your new 2,4g wifi to the same username and password that the old one had – then nothing in your house reliant on 2.4 will need to be touched!

If you are having trouble resetting your inverter to your new wifi, you are always most welcome to book in a service call and we can send a staff member out to do this for you – a call out fee will be charged to cover time and travel.

✅ iStore Inverters – How to Reconnect to Wi-Fi After Changing Internet or Router

🔌 Why Your iStore Inverter Might Be Offline

Have you recently changed your NBN plan, upgraded your router, or updated your Wi-Fi password? Your iStore hybrid inverter might now be offline. When the inverter can’t connect to the internet, your energy data won’t sync with the app or portal.

Good news — reconnecting it is simple, and you don’t need to be tech-savvy. iStore inverters use the HiSolar app (based on Huawei’s FusionSolar platform), which makes reconfiguration quick and wireless.

🧰 What You’ll Need:

  • Your smartphone (iOS or Android)

  • The HiSolar app

  • Your new Wi-Fi name and password

  • Around 10–15 minutes

📲 Download the HiSolar App:
→ Android
→ iOS

📲 Step-by-Step: Update Wi-Fi on Your iStore Inverter –

HOW TO RECONNECT YOUR INVERTER TO WIFI

1. Power on your inverter

Ensure your iStore inverter is running. You should see lights on the screen and/or buttons.

2. Connect to the inverter’s Wi-Fi

Go to your phone’s Wi-Fi settings and look for a network matching your inverter’s serial number, such as:
iStore_xxxxxx or SUN2000_xxxxxx (if Huawei-branded)

Wi-Fi Password: Changeme (with capital “C”)

This connects your phone directly to the inverter’s local Wi-Fi.

[IMAGE: Phone connected to iStore Wi-Fi network]

3. Open the HiSolar app

  • Tap “Local Access” or “Device Commissioning”

  • Select your inverter from the list (or scan the QR code on the inverter label)

[IMAGE: HiSolar app local connection screen]

4. Log in as an installer

  • Choose Installer login

  • Default installer password: 00000a (five zeros and a lowercase “a”)

[IMAGE: Installer login screen in HiSolar]

5. Go to Communication Settings

In the app, find:

  • Settings > Communication Configuration

  • Then choose Router Connection Settings (sometimes called WLAN settings)

[IMAGE: Router settings screen in HiSolar]

6. Select your new Wi-Fi network

  • Tap “Scan” or “Search” to find nearby Wi-Fi networks

  • Select your new home Wi-Fi

  • Enter your Wi-Fi password carefully

Double-check for capital letters and symbols — Wi-Fi passwords are case-sensitive.

7. Save and Connect

Tap Connect or Apply. The inverter will now try to join your Wi-Fi network.

It may take 30–60 seconds to switch over. If successful, the local hotspot will disconnect automatically.

[IMAGE: Successful connection confirmation in app]

✅ How to Know It’s Online

  • You’ll see a confirmation in the HiSolar app (green check or “Connected” status)

  • Reconnect your phone to your usual Wi-Fi

  • Open the HiSolar app in cloud mode or your iStore portal to confirm the inverter is online and reporting data

📘 Official iStore Resources:

🧠 Pro Tips

  • iStore inverters only connect to 2.4GHz Wi-Fi. Make sure your router supports 2.4GHz (most do).

  • If the inverter doesn’t appear in HiSolar, try power-cycling it (turn off, wait 30 sec, turn on).

  • Disable mobile data temporarily while connecting — some phones auto-switch networks if there’s no internet.

  • If you get stuck, check for a QR code on the inverter sticker and use the scan feature in HiSolar.

🏁 Done!

Once your iStore inverter is reconnected, it will continue to send performance data to your monitoring app and keep you updated on how much energy your home is producing and storing.

✅ SolaX Inverters – How to Reconnect to Wi-Fi After Changing Internet or Router

📡 Why Your SolaX Inverter Isn’t Connecting

If you’ve recently changed your internet provider, upgraded your router, or updated your Wi-Fi password, your SolaX inverter (like the X1 or X3 series) won’t be able to communicate with the SolaX Cloud anymore. It needs to be told your new Wi-Fi details.

Thankfully, it’s pretty straightforward to fix — especially if you have a Pocket WiFi dongle (most SolaX systems do). You’ll connect to the dongle’s temporary Wi-Fi network and enter your new Wi-Fi info via your phone or laptop.

🧰 What You’ll Need:

  • A smartphone, tablet, or laptop

  • The new Wi-Fi name (SSID) and password

  • About 10–15 minutes

  • (Optional) SolaX Cloud App
    → Android
    → iOS

🛠️ Step-by-Step: Reconnecting Your SolaX Inverter to Wi-Fi

HOW TO RECONNECT YOUR INVERTER TO WIFI

1. Make sure the inverter and Pocket WiFi dongle are powered on

The inverter must be generating or connected to AC power. Most SolaX WiFi dongles automatically broadcast a network when powered.

2. Open your device’s Wi-Fi settings

Find a network like Wifi_SXXXXXXXX

This is the dongle’s hotspot. The “S” is part of the serial number.

Password: Try 12345678 or check the label on the dongle/inverter

[IMAGE: Phone Wi-Fi screen connected to Wifi_S dongle]

3. Open a web browser

Type the following into the address bar and press enter:
192.168.10.10

On some older models, use 5.8.8.8

[IMAGE: Web browser entering 192.168.10.10]

4. Login to the dongle interface

Use:

  • Username: admin

  • Password: Either admin or the Registration No. (from the sticker on your dongle)

Example: If your dongle’s serial is SW12345678, try admin. If it’s just S12345678, try the serial itself as password.

[IMAGE: Login screen for SolaX WiFi setup page]

5. Start the Wi-Fi configuration wizard

Once logged in, look for Wizard, Network, or DHCP settings.

Click “Scan” or “Find AP” to detect Wi-Fi networks.
