The Dongle, a smart communications expansion module, serves as a crucial link between Huawei inverters and the management system. Its functionalities include facilitating communication via WLAN or FE, allowing for effective data exchange.
Here are some key aspects of the Dongle:
Communication Expansion: The Dongle extends the communication capabilities of Huawei inverters, enabling seamless connectivity with the management system. It supports WLAN (Wireless Local Area Network) and FE (Fast Ethernet) for efficient data transfer.
Device Cascading via RS485: Through RS485 communication, the Dongle enables device cascading. This means that multiple devices, including inverters or other compatible devices, can be linked together for coordinated operation. The Dongle plays a crucial role in managing this communication network.
Cascading Limitations: There is a maximum limit imposed on cascading, allowing up to 10 devices to be linked together. This ensures a structured and manageable communication network.
Smart Dongle or SmartLogger Requirement: When cascading multiple inverters, it's important to note that only one Smart Dongle or one SmartLogger is allowed. This ensures a streamlined and efficient communication setup.
The Dongle, with its communication capabilities and cascading support, enhances the connectivity and coordination of Huawei inverters within a solar energy system. It serves as a vital component in creating a robust and intelligently managed energy infrastructure.
