How to connect Huawei Fusion Solar Inverters with the Zerofy app

You can connect your Huawei Fusion Solar account using API credentials from the so-called Huawei Northbound API.

Connection your Huawei Fusion Solar Inverter

Simply click on Connect in the App and add your Huawei Nortbound API credentials. These are not your Fusion Solar user credentials.

Note: we recommend creating a dedicated Northbound account for Zerofy. If an account is shared with other services, it may lead to undesired data gaps.

How to get Huawei (Fusion Solar) Northbound API Credentials

There are 3 ways to create the Northbound API account:

Option 1. You or your installer set it up for you

This requires installer/admin permissions in Fusion Solar.

Here are the steps:

  1. Log in to FusionSolar via web browser: https://eu5.fusionsolar.huawei.com/

  2. Call up settings via System -> Company Management

  3. Click on “Northbound Management”

  4. Click “Add”

  5. Create user. Enter a date far in the future. Select installation, assign username and password (these will be your credentails for Zerofy). Set a date far in the future for access.

Important: make sure the little tab above the list of options shows V6 or V5. This is the API version that we support.

  1. Activate “Plant list” at “Status” at the very end and open it at the front with the “+” symbol. Select and add the required installation. Then close “Plant list”.

Huawei Step 6 We recommend adding just one plant to the account. While Zerofy supports multiple plants, the Northbound API limits make it less reliable to get data for several plants.

  1. Activate “Real-time plant data” at “Status” at the very end and open it at the front with the “+” symbol. Activate everything via “All”. Huawei Step 7

  2. Activate “Hourly plant data” and “Daily Plant Data” and “Monthly Plant Data”. Activate everything via “All”. Huawei Step 8 Huawei Step 8 Huawei Step 8

Option 2. Your installer requests the account from Huawei

Insteller needs to send an email to eu_inverter_support@huawei.com to request an API account for you. Provide the following information: system name, email address, and serial number of the inverter.

Option 3. You request the account from Huawei

Alternatively, you can obtain your installer’s permission for the API account and send it with your system name, email address, and serial number of the inverter to eu_inverter_support@huawei.com
