Work Instruction – Growatt GroHome Manager-X

The GroHome Manager-X combines the functions of a smart meter and a wireless connection to inverters in one system.

In addition, it acts as the central brain within Growatt’s energy management system. This allows you to easily control energy flows between Growatt products such as inverters, batteries, charging stations, and smart devices. For wireless communication, you use the ShineRFStick-X2, which you connect to the GroHome Manager-X. In this article, we explain step-by-step how to install, configure, and optimise both components for stable operation.

It is also possible to connect the GroHome Manager-X wired via RS485. In this case, the inverter does not need further monitoring. This is then handled via the GroHome Manager-X. (For example, no ShineWeLan-X2 is necessary in this case)

• Smart scheduling is not yet available via the GroHome Manager-X. This will become available during 2026.

What does the GroHome Manager-X do?

The GroHome Manager-X is the heart of the Growatt energy management system. This smart device:

• Measures, analyses and controls energy flows between:

  • Growatt inverters (including the NEO series)

  • Batteries

  • EV charging stations

  • Boilers or other smart consumers

• Supports multiple communication protocols:

  • WiFi

  • LAN

  • RF (via ShineRFStick-X2)

  • RS485 (optional)

You can connect up to 12 devices:

• Monitoring: 6 (12 microinverters)

• Export limit: 3 (6 microinverters)

Requirements for installation

For correct installation, you need the following:

• DIN rail (35 mm) in the meter cabinet

• CT clamps (included, 100A)

• Stable WiFi or LAN connection

• ShineRFStick-X2

• Latest firmware version

Tip: working in a metal cabinet? Make sure the antennas are placed outside the cabinet for optimal signal.

Step 1 – Mounting the GroHome Manager-X

Placement on DIN rail

Click the device firmly onto the DIN rail. Check that it is securely fixed.

Connecting antennas

Connect the WiFi and RF antennas. Place both outside the metal cabinet for good range.

Mains power connection

• Use 1.5–2.5 mm² cables

• Remove approximately 7 mm insulation

• Connect to: L1, L2, L3, N and PE

Placing CT clamps

• Click the clamp around the phase wire (pay attention to orientation!)

• White wire → CT+

• Black wire → CT−

RS485 connection with inverters (optional)

• Use twisted, shielded cable (AWG 16–22)

• Connect the shielding to earth

Step 2 – Installing the ShineRFStick-X2

The ShineRFStick-X2 provides wireless communication between the inverter and the GroHome Manager-X.

How to install the stick:

1. Remove the USB cover from the inverter

2. Insert the ShineRFStick-X2 into the USB port (marking facing forwards)

3. Turn the lock until it clicks into place

4. Attach the RF antenna

Use the stick only with Growatt inverters. Never connect an external USB power supply.

Step 3 – Configuration via the ShinePhone app

1. Download the app

Search for ShinePhone in the App Store or Google Play. You can also scan the QR code on the packaging.

2. Create an account

3. Add a Power Station

• Add a datalogger

• Scan the QR code on the GroHome Manager-X

• Follow the steps in the app

4. Choose your connection method

• WiFi: Connect via Bluetooth, select your router and enter the password

• LAN: The connection is established automatically

5. Pair RF devices (according to user manual p. 58)

• Press the button on the GroHome Manager-X twice

  • The yellow LED starts flashing (RF pairing mode active)

• Press the button underneath the ShineRFStick-X2 twice

  • Here the yellow LED also starts flashing

• The app automatically recognises the devices (such as the inverter with the ShineRFStick-X2)

This process takes about 2 minutes.

In the app, under Devices > GroHome Manager-X (click) > Devices, you can view the list of paired devices.

Configuration of RS485 can be found on page 63 of the manual.

LED status: what does each colour mean?

Common issues (and solutions)

No communication with inverter?
Check if the ShineRFStick-X2 is properly installed and if the antenna is outside the cabinet.

Need to reset device?
Hold the button for 6 seconds until the white LED lights continuously.
