FusionSolar App Quick Settings Operation Procedure

Download and install the FusionSolar app
Register an installer account (optional, for installers without an account)
Log in and start Setup wizard
Create an owner account
Check the device status

This document applies to the following scenarios:

• Inverter with built-in WLAN for local commissioning
• Inverter with a Smart USB-WLAN Adapter for local commissioning
• In RS485 cascading networking.
• SDongleB-06+Commercial inverter (without WLAN module)
• Inverter with a SmartLogger for local commissioning
• The figures are for reference only.
• The initial password for connecting the inverter WLAN is Changeme.
• The initial password for connecting to the Smart USB-WLAN adapter is Changeme.
• The initial password for the installer account is 00000a. If the system prompts you to change password, set a new password and then log in to the system.
• Some device do not support the initial password. You need to set the initial password upon the first connection. Set the password before log in to the system.
• To ensure account security, change the password periodically and keep the new password in mind. Not changing the initial password may cause password disclosure. A password left unchanged for a long period of time may be stolen or cracked. If a password is lost, devices cannot be accessed. In these cases, the user is liable for any loss caused to the PV plant.

Downloading and Installing the FusionSolar App

Method 1: Download and install the app from the app store.

• Huawei phone users: Search for FusionSolar in Huawei AppGallery.
• iPhone users: Search for FusionSolar in the App Store.
• Other mobile phone users: Select method 2.

Method 2: Scan the QR code to download and install the app.

https://intl.fusionsolar.huawei.com/pvmswebsite/nologin/assets/build/index.html#/jumppage

Users who select method 2 can select the download method based on the mobile phone type.

• Huawei mobile phone users: Download from Huawei AppGallery.
• Non-Huawei phone users: Download on a browser.

Note:
When you select Download via the Browser, if a security warning message is displayed indicating that the app is from an external source, tap ALLOW.

Register an Installer Account (Optional, for Installers Without an

Account)

Register the first installer account and create a company account.

To create multiple installer accounts for the same company, log in to the FusionSolar app to Add User or Invite User.

In some regions, the function of inviting users is not supported. The actual page prevails.

Log in and Start Setup Wizard

• WLAN/FE SDongle+Built-in WLAN of the Inverter
  

The grid code is set to N/A by default (automatic startup is not supported). Set the grid code based on the area where the PV plant is located.
If Sync phone time is enabled, the time and time zone of the inverter are synchronized with those of the mobile phone.

In a non-cascading scenario, the step of Searching for cascaded inverters is not involved.

In a non-Battery scenario, the step of Energy storage control is not involved.

Set network parameters and domain name.

Add a plant.

• SDongleA-03+Distributed inverter/SDongleB-06+Commercial inverter (without WLAN module)

In the MBUS cascading scenario, use the USBWLAN module to connect to the inverter, and then log in to the commissioning page of inverter to set the parallel parameter. 

Remove the USB-WLAN module, install the SDongleB-06. ![HUAWEI FusionSolar App

• Figure 15](https://manuals.plus/wp-content/uploads/2024/01/HUAWEI- FusionSolar-App-Figure-15.png)

In cascading scenarios, you need to manually search for cascaded inverters.

Upload the SN file to search for cascaded inverters. (On the app connection page, click MBUS whitelist to generate an SN file.)

Set communication parameters based on the actual networking scenario.

DHCP, disable DHCP and manually assign an IP address.
WLAN communication| Select the router you want to connect to, enter the password, and tap Connect Router.
4G communication| By default, APN mode is set to Automatic. When this mode cannot be used to access the Internet, set the parameter to Manual. In this case, set the parameters related to the SIM card based on the information obtained from the carrier.

Set the Domain name to intl.fusionsolar.huawei.com and Port number to 27250.

Add a plant.

Local Commissioning Using a Smart USB-WLAN Adapter
Note:
Before commissioning a commercial inverter, connect the 4G Smart Dongle to identify parameters. If the indicator status is normal, remove the Smart Dongle, and then connect the USB-WLAN adapter to start commissioning.

In a non-cascading scenario, the step of searching for cascaded inverters is not involved.

Set network parameters and domain name.

4G communication
Enabled Monitor the PV plant through the management system.
Set the Domain name to intl.fusionsolar.huawei.com and Port number to 27250.
By default, APN mode is set to Automatic. When this mode cannot be used to access the Internet, set the parameter to Manual. In this case, set the parameters related to the SIM card based on the information obtained from the carrier.

Connect to the management system.

After the commissioning is complete, remove the USBWLAN module, install the 4G module. Check the indicator status. After the indicator is steady green or blinks at shortintervals (on for 0.2s and then off for 0.2s) add a PV plant.

FAQ. Physical Layout Design (With Optimizers)

1. The physical layout must be configured for optimizers. When an optimizer is faulty, it can be quickly located and replaced based on the physical layout.
2. The optimizer disconnection detection is available only after the physical layout is complete. Perform optimizer disconnection detection and view the result on the Optimizer layout screen.
   

Step 1 After determining the installation position of an optimizer, remove the SN label from the optimizer and attach it to the physical layout template.

Step 2 Take a photo of the template with the QR code attached.

Note: Ensure that the four positioning points on the template are within the frame.

FAQ . Physical Layout Design

Indicators on the Smart Dongle

secured and powered on.
Green| Blinking in a 2-second cycle (on for 0.1s and then off for 1.95)| Normal| Dialing (duration < 1 min)
Abnormal| If the duration is longer than 1 min, the 4G parameter settings are incorrect. Reset the parameters.
Blinking at long intervals (on for 15 and then off for 1s)| Normal| The dial- up connection is set up successfully (duration < 30s).
Abnormal| If the duration is longer than 30s, the settings of the management system parameters are incorrect. Reset the parameters.
Steady on| Normal| Successfully connected to the management system.
Intervals Blinking at short  (on for 0.2s and
then off for 0.25)| The inverter is communicating with the management system through the Dongle.
Red| Steady on| Abnormal| The Dongle is faulty. Replace Dongle.
Blinking at short intervals (on for 0.2s and then off for 0.2s)| The Dongle has no SIM card or the SIM card is in poor contact. Check whether the SIM card has been installed or is in good contact. If not, install the SIM card or remove and insert the SIM card.
Blinking at long intervals (on for 15 and then off for 1s)| The Dongle falls to connect to the management system because it has no signals, weak signal, or no traffic. If the Dongle is reliably connected, check the SIM card signal through the APP. If no signal is received or the signal strength is weak, contact the carrier. Check whether the tariff and traffic of the SIM card are normal. If not, recharge the SIM card or buy traffic.
Blinking red and green alternatively| Blinking at long intervals (red for 15 and green for 1s)| No communication with the inverter
•Remove and insert the Dongle.
•Check whether inverters match the Dongle.
•Connect the Dongle to other inverters. Check whether the Dongle or the USB port of the inverter is faulty.
Blinking at short intervals (red for 0.2s and green for 0.2s)| Normal| The Dongle is being upgraded locally.
