NOTICE
The information in this document is subject to change without notice. Every effort has been made in the preparation of this document to ensure accuracy of the contents, but all statements, information, and recommendations in this document do not constitute a warranty of any kind, express or implied.

• SDongleA-05 (Dongle for short) is a smart communications expansion module that works with Huawei inverters to implement communication between inverters and the management system using WLAN or FE.
• A Dongle can be used for device cascading using RS485 communication (inverter cascaded or inverters cascaded with other devices). A maximum of 10 devices can be cascaded.
• When multiple inverters are cascaded, only one Smart Dongle or one SmartLogger is allowed.

Communication Scenario

• Inverters with different appearances are used in the same communication scenario. The inverters in this document are used as an example.
• In the networking, the inverter where the Dongle is installed is the master inverter, and other inverters are slave inverters. Slave inverters can communicate with the Dongle through cascading.
• In the communications scenario, ensure that the wireless network of the inverter and router is not disturbed and that the signal is normal.

Number of devices in the RS485 communication scenario

Meters)**

10

| 10| n ≤ 9| ≤ 9 – n
3 (with energy storage)| n ≤ 2| ≤ 2 – n
3 (with single-phase inverters)| n ≤ 2| ≤ 2 – n

If devices are connected to the 485B2 and 485A2 ports of the master inverter, the devices are not included as cascaded devices.

Inverter Model Requirements

Steady on

|

Abnormal

| The Dongle is faulty. Replace the Dongle.

Blinking red and green alternatively

|

Blinking at long intervals (on for 1s and then off for 1s)

| No communication with the inverter

•   Remove and insert the Dongle.

•   Check whether inverters match the Dongle.

•   Connect the Dongle to other inverters. Check whether the Dongle or the USB port of the inverter is faulty.

NOTICE Before setting parameters, ensure that the AC and DC side of the inverter has been powered on.

Install the FusionSolar app. Perform the Setup wizard operations. If you have performed such operations, skip this step. If not, you can scan the QR code below to obtain the app quick guide which describes the Setup wizard operations.

Abnormal

| Failed to connect to the management system. Check whether the parameters for connecting inverters to the management system are properly set. If not, set the parameters correctly.

Green

| Blinking at short intervals (on for 0.2s and then off for 0.2s)|

Normal

| The inverter is communicating with the management system through the Dongle.

Commission the inverter locally via the Smart Dongle WLAN. If the Smart Dongle WLAN is disabled, log in to the FusionSolar app and tap the plant name on the Home screen to access the plant screen. Tap Devices and then tap SDongleA-05. Choose O&M Authorization > WLAN wakeup > Confirm to enable the Smart Dongle WLAN.

NOTE If the inverter has a built-in WLAN module, the Smart Dongle WLAN is disabled by default. If the inverter does not have a WLAN module, the Smart Dongle WLAN is enabled by default.
