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
•
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.

Before setting parameters, ensure that the AC and DC side of the inverter has been powered on.
2.
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

•
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.
