The SmartgridOne Controller communicates with the Huawei SCharger via (Ethernet/Wi-Fi).
For the most stable connection with the Controller, it is recommended to use a hardwired Ethernet (FE) connection.
While the charger supports Wi-Fi, a wired Ethernet connection is strongly recommended for reliable control by the Smart Grid Controller.
To enable control by the Controller, you must perform a one-time configuration on the charger itself to enable the Modbus protocol.
Use the FusionSolar App (Installer account) solely to configure the network and Modbus settings.
By default, the charger does not accept commands from external controllers. You must enable this:
Important If Modbus TCP is not enabled here, the Controller cannot detect or control the charger.
To ensure the Controller never loses connection, assign a static IP:
Now that the charger is configured, you can add it to the Controller.
Enter the following settings in the Eniris portal:
| Setting | Value |
|---|---|
| IP Address | The static IP you assigned in step 3 (e.g., 192.168.1.50) |
| Port | 502 |
| Slave ID | 1 (Default) |
