Brand New Huawei Communication Networking of the SDongleA-03 (4G) Smart Dongle

DongleA-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.The information in this document is subject to change without notice.

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.2Installation and Commissioning•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.Install the SIM card in the arrow direction.Ensure that the Dongle shell is properly installed.1.Install a SIM card.Recommended Monthly Traffic for SIM Card PurchasesTraffic SupportInvertersWithout a power sensor or energy storage10 MB + 4 MB x Number of inverters•Device performance data can be refreshed every 5 minutes.•The Dongle logs, inverter logs, and IV diagnosis data can be exported monthly.
