      Set up API access - Huawei FusionSolar API

      This article describes how to set up and share the PV data of your Huawei solar system through the Solytic API interface.

      For Solytic to access data from the FusionSolar API, we need the access details for your sites in the FusionSolar portal. The following is a step by step guide on how to set up third-party access. This will enable Solytic to retrieve data from your installations within the FusionSolar portal, using  the API interface.

      Please note:

      As the total number of data queries to the FusionSolar API is calculated per system/user and is subject to strict limitations, it may happen that the data for some systems is updated less frequently or - if the limit is exceeded - that no data for a system can be retrieved. We therefore recommend creating a separate account for each system in the FusionSolar portal in order to take the limitations into account and maintain regular data synchronization.

      The following steps are carried out in the FusionSolar portal:

      1. Log in to the FusionSolar portal as a company administrator, select System > Company Management > Northbound Management, and then click on Add.

      2. Provide the following information in the pop-up window:

        • Username: Note, the northbound API username can not be the same as the FusionSolar account.
        • Password: Enter the password for the northbound API username (
          The password must contain 8 to 32 characters)
        • Associated user: Select the user from the dropdown
          • Before adding the northbound API user, ensure that the associated  user has been authorized in the user management (System > Company Management > User Management). User should be company administrator and should have access to all plants of the company or at least the plants that are needed for the nortbound API user.


        • Deadline: Select the time when the data provisioning via the API interface should end (ideally far in the future)
        • Basic APIs: Turn the toggle on
        • Select companies/plants:
          • ... either select the company (in this case the northbound API user will be authorized to query plant-level data of all existing and future plants of selected company)
          • ... or select the specific plants (the northbound user will be authorized to query plant-level data of the selected plants)

      3. Create the plant in Solytic and add a new data source.

        When adding the data source, select the connection type Huawei FusionSolar API and enter your access credentials for the FusionSolar portal nortbound API user in the connection settings.

        The plant ID is part of the URL for the respective plant in the FusionSolar portal. Navigate to the plant overview there, copy the Port NE=12345 from the URL, and add it as the plant ID in Solytic.

      4. The settings for data transmission interval and data delay may vary due to the limitations of the Huawei FusionSolar API. Therefore, we recommend a transmission interval of 24 hours, and the data delay can remain open. For individual determination of these details, feel free to contact support@solytic.com.
