- SDongleA-03 Smart Dongle (the “Dongle” for short) is a smart communications expansion module that works with Huawei inverters to implement wireless communication between inverters and management systems through the 4G network.
- When multiple inverters are cascaded, only one Dongle or one SmartLogger is allowed.
Communication Scenario
RS485 communication scenario
NOTE
- 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.
- This document uses the RS485 communication scenario as an example. For details about the MBUS communication scenario, see the user manual.
- This document uses connection to Huawei FusionSolar Smart PV Management System as an example. For details about connection to a third-party management system, see the user manual.
- The inverter model is subject to change without notice. The model information and device appearance in this document are for reference only.For more details, see the user manual.

Number of Devices Required for Networking
| 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 power meters and |
energy storage devices)**
10| n ≤ 9| ≤ 9 – n
2| n ≤ 1| ≤ 1 – n
NOTE
- The number of devices that can be cascaded varies with the Dongle model. You can view the maximum number of devices that can be connected to the Dongle from the label on the external package.
- If cascaded inverters include a single-phase inverter or are connected to batteries, a maximum of three inverters can be cascaded.
- If devices are connected to the RS485-2, RS485_2, or 485B2 and 485A2 ports of the main inverter, the devices are not included as cascaded devices.
Installation and Commissioning
1. Install a SIM card.
NOTE
-
You need to prepare a standard SIM card (size: 25 mm x 15 mm; capacity: ≥ 64 KB).
When connecting to Huawei FusionSolar Smart PV Management System, prepare a SIM card based on the traffic requirements in the following table. -
Before installing a SIM card, you need to remove the Dongle from an inverter.
| Recommended Monthly Traffic for SIM Card Purchases | Traffic Support |
|---|---|
| Inverters | Without a power sensor or energy storage |
| inverters | •Device performance data can be refreshed every 5 minutes. |
•The Dongle logs, inverter logs, and IV diagnosis data can
be exported monthly. The Dongle and inverters can be upgraded monthly.
With a Power sensor| 10 MB + 7 MB x Number of inverters
With energy storage| 13 MB + 7 MB x Number of inverters +
5 MB x Number of DC-DC converters
With a power sensor and energy storage| 13 MB + 7 MB x Number of inverters +
5 MB x Number of DC-DC converters
With Smart PV Optimizers| Inverter data usage + 2 MB + 0.2 MB x
Number of Smart PV Optimizers
NOTE
Ensure that the AC or DC side of the inverter has been powered on.
3. 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.

| LED | Remarks | Description |
|---|---|---|
| Color | Status | |
| N/A | Off | Normal |
| Yellow (blinking green and red simultaneously) | Steady on | The Dongle Is |
secured and powered on.
Green| Blinking in a 2-second cycle (on for 0.1s and then off for 1.9s)|
Normal| Dialing (duration < 1 min)
Abnormal| If the duration is longer than 1 min, the 4G parameter settings are
incorrect. Reset the parameters.
Blinking at long Intervals (on for 1s and then off for 1s)| Normal| The dial-
up connection is set up successfully (duration < 30s).
Abnormal| If the duration is longer than 30s, the settings of the management
system parameters are incorrect. Reset the parameters.
Steady on| Normal| Successfully connected to the management system.
Blinking at short intervals (on for 0.2s and then off for 0.2s)| The inverter
is communicating with the management system through the Dongle.
Red| Steady on| Abnormal| The Dongle Is faulty. Replace Dongle.
Blinking at short intervals (on for 0.2s and then off for 0.2s)| The Dongle
has no SIM card or the SIM card is in poor contact. Check whether the SIM card
has been installed or is in good contact. If not, install the SIM card or
remove and insert the SIM card.
Blinking at long intervals (on for 1s and then off for 1s)| The Dongle fails
to connect to the management system because it has no signals, weak signals,
or no traffic. If the Dongle is reliably connected, check the SIM card signal
through the app. If no signal is received or the signal strength is weak,
contact the carrier. Check whether the tariff and traffic of the SIM card are
normal. If not, recharge the SIM card or buy traffic.
Blinking red and green alternatively| Blinking at long intervals (red for 1s
and green 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.
Blinking at short intervals (red for 0.2s and green for 0.2s)| Normal| The
Dongle is being upgraded locally.
