HUAWEI Zero Intestines SDongleB 06 Smart Dongle

Product Information

The SDongleB-06 Smart Dongle is a device used for communication in a networking scenario. It supports RS485 communication and can act as a slave or master inverter. The dongle can be used with a variety of devices, including power meters and energy storage systems. It has a maximum capacity to connect up to 10 devices, including 3 slave inverters (or 2 with single-phase inverters). The dongle also supports communication with a third-party management system.

Product Usage Instructions

1. Install a SIM card: To use the dongle, insert a SIM card. The recommended monthly traffic for SIM card purchases depends on the type of devices connected. Without a power meter or energy storage, the recommended monthly traffic is 15 MB + 4 MB x Number of inverters, and the data can be refreshed every 5 minutes. With a power meter, the recommended monthly traffic is 15 MB + 7 MB x Number of inverters. With energy storage, the recommended monthly traffic is 18 MB + 7 MB x Number of inverters x Number of DC-DC converters + 5. If using Smart PV Optimizers, add 2 MB + 0.2 MB x Number of Smart PV Optimizers to the inverter data usage.
2. Install the Dongle: Connect the dongle to the inverter’s USB port. Ensure that the dongle enclosure is properly installed. Also, make sure that the AC and DC sides of the inverter are powered on before setting parameters.
3. Install the FusionSolar app: Download and install the FusionSolar app on your mobile device. Follow the Setup wizard operations to configure the settings. If you have already performed the setup, you can skip this step. Scan the provided QR code to obtain the app quick guide for more information on the Setup wizard operations.

• SDongleB-06 Smart Dongle (also referred to as the Dongle) is a smart communications expansion module that works with Huawei inverters to implement wireless communication between inverters and the management system through the 4G network.
• If multiple inverters are cascaded, use either a Dongle or a SmartLogger for networking. You cannot use two networking methods at the same time.

Communication Scenario

RS485 Communication

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 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.
• For details about Dongle performance parameters and supported inverter models, see the user manual.

Number of Devices Required for Networking

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 devices are connected to the RS485-2, RS485_2, or 485B2 and 485A2 ports of the master 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.

2. Install the Dongle

NOTE
Ensure that the AC and DC sides of the inverter are powered on before setting parameters.

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.

NOTE

  * You can obtain SIM card parameters from the SIM card carrier. For more details about how to use the app, scan the QR code to obtain related documents.
  * To create multiple installer accounts for a company, log in to the app and then tap Add user.

4. 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 SDongleB-06. 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.
