Installer

To ensure your inverter integrates smoothly into the HEMS system, please follow the steps below:

Step 1 – Confirm connection methods and interface parameters

The enjoyelec HEMS Controller supports Modbus-RTU communication with most LH-Sunsaver TH Series Inverters models. A standard RS485 connection is required to link the two devices.

Please refer to the LH-Sunsaver TH Series User Manual to identify the exact location of the RS485 interface, verify the factory default parameters, and understand how to modify them if necessary.

Step 2 – Connect the inverter to the HEMS Controller

Connect the RS485 cable to the corresponding interface on the HEMS Controller based on the inverter’s port definitions.

(Note: Detailed interface parameters and wiring examples for the HEMS Controller can be found in the examples below or in the specific HEMS User Manual.)

Step 3 – Configure interface parameters in the enjoyelec app

After completing the physical wiring, power on both devices. Open the enjoyelec app to bind the device and enter the communication parameters that match your actual setup.

(For step-by-step app instructions, please refer to the enjoyelec User Manual.)

Once configured, the LH-RESS-TH12K01CE-X inverter will be fully integrated into the HEMS, enabling you to monitor real-time data and control the device remotely via the app.

Detailed Example: Integrating Model LH-RESS-TH12K01CE-X

Step 1 – Identification and Verification

For the LH-RESS-TH12K01CE-X model, the communication interface is located at the bottom of the unit. According to the manual, the “RS485” port is the designated terminal.

Specifically, the RS485 port is an 8-pin RJ45 Terminal marked as “RS485.” For RS485 communication, the pinout for PIN 4 (Blue) and PIN 5 (Blue & White) is shown in the diagram below:

• Default Baud Rate: 115200
• Default Modbus Address: 1

Step 2 – Physical Wiring

Ensure that the RS485 communication parameters on both the inverter and the HEMS Controller are configured to match.

Please note that the LH-Sunsaver inverter operates at a default baud rate of 115200, while the HEMS Controller defaults to 9600. You will need to change the Controller’s port setting to 115200 via the enjoyelec app to establish successful communication.

  • Pay close attention to the A and B cable color coding to ensure the wiring sequence on the Controller side matches the Inverter side perfectly.
  • If a different baud rate is required, please refer to the HEMS Controller manual or use the enjoyelec app to adjust the controller’s port settings.

Step 3 – App Configuration

With the physical connection established:

  1. Select Device: In the enjoyelec app, choose the correct device type, brand (LUMENHAUS), and model.

2. Set Protocol: Define the communication protocol, physical port number, and matching parameters (Baud rate/Address).

3. Establish Connection: Once saved, the Controller will pair with the inverter. You can then begin data collection and active energy management.
