Huawei Smart Dongle – 4G Mobile Network adapter
SDongleA-03 (HUA-SMART-DONGLE-4G) is a smart communications expansion module that works with Huawei inverters (3KTL-M0 to 20KTL-M0) to implement wireless communication between inverters and the management system through the 4G network.
A Smart Dongle can be used for daisy chaining devices using RS485 communication (inverter daisy chained, or inverters connected with other devices). A maximum of 10 devices can be connected together. When multiple inverters are connected together, only one Smart Dongle or one SmartLogger is allowed.
