To ensure that your inverter can be smoothly integrated into the HEMS system, it is recommended to follow the steps below:

Step 1 – Confirm the connection method and interface parameters of the inverter to the HEMS system

• Modbus-RTU communication has been established between the HEMS Controller and most models of Huawei Inverters. You can use RS485 wiring to connect the two devices.
• Refer to the Huawei Inverter User Manual to confirm the exact location of the RS485 interface, as well as the factory default parameters and the method for modifying them.

Step 2 – Establish the correct connection between the inverter and the HEMS Controller

• Based on the RS485 interface parameters of the Huawei Inverter, connect the RS485 cable to the corresponding RS485 interface of the HEMS Controller.
  (The interface parameters and configuration method for the HEMS Controller can be found in the detailed examples below or in the User Manual and other materials.)

Step 3 – Enter interface parameters in the enjoyelec app

• After completing the wiring, power on the devices. Open the Enjoyelec app to bind the device and enter the interface parameters that match the actual setup.
  (For detailed instructions on configuring the app, please refer to the User Manual.)
• Once the configuration is complete, the Huawei Inverter will be integrated into the HEMS system, allowing you to perform functions such as querying and controlling the device via the app.
