Note:

• 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 devices do not support the initial password. You need to set the initial password upon the first connection. Set the password before logging 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.

1. 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.

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.

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

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.

2. Register an Installer Account (Optional, for Installers Without an Account)

Register the first installer account and create a company account.

Note: To create multiple installer accounts for the same company, log in to the Fusion Solar app to Add User or Invite User.

Both the email address and username can be used to log in to FusionSolar app.

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

3. Log in and Start Setup Wizard

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

Scan the QR code of the inverter connected to the Huawei SmartPVMS. If there is no QR code, tap "Enter SN".

Log in to the app as an installer. The initial password of the installer is 00000a. If the system prompts you to set a password, set the password and login. First power-on and change it immediately after login.

At the first login, the Quick settings screen is displayed by default.

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

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.

Check whether the detected devices are consistent with the actual connected devices.

Cascaded inverters

Networking mode

Searching for cascaded inverters

SDongleA-05+Distributed inverter/SDongleB-06+Commercial inverter (without WLAN module)

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

Remove the USB-WLAN module, install the SDongleB-06.

Log in to the app as an installer. If the system prompts you to set a password, set the password and login first power-on and change it immediately after login.

At the first login, the Quick settings screen is displayed by default.

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.

Check the indicator status. When the indicator blinks green at an interval of 2s (on for 0.1s and then off for 1.9s), remove the 4G Smart Dongle.

Scan the device QR code to connect the device to the Huawei SmartPVMS. If there is no QR code, tap "Enter SN".

The initial password is 00000a.

At the first login, the Quick settings screen is displayed by default.

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.

Local Commissioning Using the SmartLogger of the Inverter

Scan the device QR code to connect the device to the Huawei SmartPVMS. If there is no QR code, tap "Enter SN".

Log in to the app as an installer. The initial password is 00000a.

Ensure that the devices are consistent with the actual connected devices.

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.

Select the ESS Installation Environment and working mode settings of the battery.

Monitor the PV plant through the management system. Set the Domain name to intl.fusionsolar.huawei.com and Port number to 27250.

When the SmartLogger connects to the SmartPVMS over the wireless network, set Mobile network parameters and Network mode.

When the SmartLogger connects to the SmartPVMS over a wired network, set Wired network parameters.

4. Create an owner account

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

After receiving the invitation, the user accesses the registration page to register an account.

5. Checking the Device Status

Checking the Device Status Using Device Commissioning

Note:

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

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. Positioning point for photographing.

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

FAQ. Physical Layout Design

Tap a plant that is equipped with optimizers.

Tap Physical layout.

Set optimizer parameters.

Tap to upload the physical layout template.

Tap to add a physical layout template.

Take a photo of the template with the QR code attached, or select the photo from your phone album.

Note: For some unidentified QR codes, manually bind them.

Hold and drag to adjust the sequence.

To create other layouts, log in to the SmartPVMS.

The existing physical layout will be overwritten by a new one. Are you sure you want to generate a new layout?
