Huawei Smart Dongle - 4G Mobile Network adapter

SDongleA-03 (HUA-SMART-DONGLE-4G) is a smart communications expansion module that works with Huawei inverters (see compatibility below) to implement wireless communication between inverters and the management system through the 4G network.

A Smart Dongle can be used for daisy chained 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.
