⚙️ How does it work?​

Growatt inverters do not support Modbus TCP directly. A Growatt ShineLink-X is required for Modbus TCP. The ShineLink-X consists of two components:

  • ShineRFStick-X — a dongle that plugs into the inverter's USB port
  • ShineLanBox — a box that connects to the local network via Ethernet

The ShineRFStick-X and ShineLanBox communicate wirelessly via RF (range up to 200 metres in open air). The ShineLanBox translates between Modbus TCP (network) and the inverter.

🧰 Requirements​

  • Currentt Navigator (connected to the local network)
  • Growatt ShineLink-X (includes ShineLanBox + ShineRFStick-X)
  • Ethernet cable (RJ-45, between ShineLanBox and network switch/router)
  • Power adapter (included with the ShineLink-X)

1️⃣ Step 1: Connect ShineRFStick-X to the inverter​

The ShineRFStick-X is a dongle that plugs into the inverter's USB port.

  1. Rotate the USB cover on the inverter counterclockwise to remove it
  2. Rotate the ShineRFStick-X lock so the triangle faces up and is centred
  3. Insert the ShineRFStick-X into the USB port on the inverter
  4. Press the lock and rotate clockwise until it clicks into place
Check the LED

After installation, the LED on the ShineRFStick-X should flash quickly (every 0.2 seconds). This means the USB port has found the inverter. If the LED is off, check the connection.

2️⃣ Step 2: Connect ShineLanBox to the network​

  1. Connect an Ethernet cable (RJ-45) to the RJ-45 port on the ShineLanBox
  2. Connect the other end to your network switch or router
  3. Connect the power adapter to the ShineLanBox
  4. The ShineLanBox automatically obtains an IP address via DHCP

After booting, the Power LED turns on, the Network LED turns on (connected to network) and the Device LED flashes (connected to ShineRFStick-X).

3️⃣ Step 3: Configure the ShineLanBox​

The ShineLanBox has a built-in web interface for configuration.

  1. Find the IP address of the ShineLanBox via your router (DHCP client list)
  2. Open a browser and navigate to the IP address of the ShineLanBox
  3. Log in to the web interface
  4. Check the following settings:
SettingValue
Modbus TCPEnabled
TCP port502
Modbus address1 (must match the inverter)

4️⃣ Step 4: Configuration in the Currentt Navigator​

After configuring the ShineLanBox, the inverter must be added in the Currentt Navigator.

  1. Click the settings icon (top right of the screen)
  2. Choose Setup Wizard
  3. Follow the on-screen steps
