• 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.
• The Smart Dongle can be used for the RS485 device cascading (inverter cascading or inverter
cascading with other devices). For the SUN2000-2KTL/3KTL/4KTL/5KTL-L0, only one inverter can
be connected.
• When multiple inverters are cascaded, only one Smart Dongle or one SmartLogger is allowed.

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 Hosting Cloud, 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.

Installation and Commissioning
NOTE
•
If the SIM card of the Dongle has a PIN code, install the Dongle first. Otherwise, skip the first
step. You can obtain the PIN code from the carrier.
•
When connecting to the Huawei FusionSolar management system, you do not need to set
parameters for connecting inverters to the management system on the SUN2000 app.
Installing the Dongle (Optional)
2.1
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 Hosting Cloud, 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.

1.9s), remove the Dongle.
Setting Inverter Parameters at the Local Router Using
2.2
the SUN2000 App
Before setting parameters, ensure that the following conditions are met:
1. To obtain the SUN2000 App, scan the QR code or search for SUN2000
in Google play to download and install the app. The app version is
3.2.00.001 (Android) or later.
2.
Ensure that the AC or DC side of the inverter has been powered on.
3.
Connect the Bluetooth model, WLAN model or USB data cable to the
inverter USB port to ensure that inverters can communicate with the
SUN2000 app.
The following describes how to set the SUN2000 app (3.2.00.001) on the
Android UI.
Bluetooth/WLAN Connection
Inverter USB port
Log in to the SUN2000 app as Advanced User, set basic parameters for the master inverter on
1.
the Quick settings screen, and synchronize some parameters of the master inverter to the
slave inverters on the PV plant configuration screen.
NOTE
•
When the WLAN connection is used, the initial name of the WLAN hotspot is Adapter-WLAN
module SN, and the initial password is Changeme.
•
Use the initial password upon first power-on and change it immediately after login. To
ensure account security, change the password periodically and keep the new password in
mind. Not changing the initial password may cause password disclosure. A password left
unchanged for a long period of time may be stolen or cracked. If a password is lost, devices
cannot be accessed. In these cases, the user is liable for any loss caused to the PV plant.
•
If you log in to the SUN2000 app after the device connects to the app for the first time or
factory defaults are restored, the Quick settings screen is displayed. If the Quick settings
screen is not displayed, you can set basic inverter parameters under Grid Parameters,
User Parameters, and Comm. Parameters on the Settings screen.

The Dongle is not secured or is not powered on.
The Dongle is secured and powered on.
Normal
Dialing (duration < 1 min)
Abnormal If the duration is longer than 1 min, the 4G
parameter settings are incorrect. Reset the
parameters.
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.
Normal
Successfully connected to the management
system.
The inverter is communicating with the
management system through the Dongle.
Abnormal The Dongle is faulty. Replace Dongle.
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.
The Dongle fails to connect to the management
system because it has no signals, weak signal,
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.
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.
