The Huawei Smart Dongle WLAN-FE is an intelligent communication module designed to connect Huawei SUN2000 inverters to the network via Wi-Fi or Ethernet. The device enables remote monitoring, firmware updates, and control of solar power plant parameters via the FusionSolar platform. Its use allows for effective real-time tracking of system performance and quick response to potential deviations.
The dongle is compatible with all current Huawei inverters in the SUN2000 M0, M1, M2, M3, M5, and Smart String series. Thanks to its simple Plug & Play design, the module connects without additional configuration and is automatically recognized by the inverter. The built-in status indicator provides convenient connection monitoring during installation.
