Huawei - Fusionsolar

To allow Sunreport to access the plant data shown on Huawei’s Fusionsolar website, you must enable the application’s automatic access (i.e., enable the APIs — Application Programming Interface).
This means creating a special user with its own username and password that Sunreport will use to request the data.

Only the administrator of an installer account is able to perform this operation.
It cannot be done from a user account (provided by the installer).
It is still possible to create your own Fusionsolar account (installer registration from the login page indicated below) and add inverters by providing type, model, and serial number.

To create the user:

1. Log in to Fusion Solar ( https://eu5.fusionsolar.huawei.com/unisso/login.action ).
2. From the main dashboard, go to System > Enterprise Management.
3. In the Enterprise Management section, select Northbound Management and click Add to create the API account (Add button on the right).
4. In the new window:
   1. Fill in the fields marked with a red asterisk. Write down the chosen userid and password. In the Associated Account field, enter an administrator or installer user previously created in the “User Management” section.
   2. Select the company that manages the plants (the main account) by clicking the first box in the list Select Company/Plants and then clicking the arrow. Then select all the plants you want to monitor and click the arrow again. This will populate the two areas Selected Company and Selected Plants.
   3. Grant permissions: click the Basic API switch.
5. In Sunreport, select the plant,
   Plant Settings > Connected Devices > Add new > Huawei
   and enter the userid and password you created in step 4.1.

Sunreport will then have access to the plants created in the Fusionsolar account and to those associated with it that were created in other accounts.

In FusionSolar, the data of plants not created directly in your own platform require explicit authorization for API access from the plant owner.

The plant owner must log into their Fusionsolar App and activate the permissions as shown in the image:

To check the permission status, go to:

Plants → Plant Management

In the “Operation” column, you can distinguish:

• plants created in your own platform (do not require authorization)
• plants without authorization
• plants for which authorization has been granted.

Verify that the plant of interest has received authorization and that “API Access” is included among the permissions.
To view authorization details, click the sheet-shaped icon.

The owners of the plants can be found here:
Monitoring → Monitoring → Plant Users
