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.
If cascaded inverters include a single-phase inverter or are connected to batteries, a maximum of three inverters can be cascaded.
When multiple inverters are cascaded, only one Smart Dongle or one SmartLogger is allowed.

Communication Scenario

Note

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

Limited Number	Actual Number
Maximum number of devices that can be connected to the Dongle	**Number
of slave inverters**	**Number of other devices (such as Smart Power Sensors

and energy storage devices)**

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

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.

In areas (such as the UK) where the FusionSolar app is not available, or when a third-party management system is used, only the SUN2000 app can be used for commissioning. This document uses the FusionSolar app as an example to describe the commissioning method. For the SUN2000 app, perform operations as required.
To obtain the SUN2000 App, scan the QR code or search for “SUN2000” in Huawei AppGallery, download the latest installation package, and install the SUN2000 app by following the instructions. The SUN2000 app version should be 3.2.00.002 (Android) or later.
