Setting up (or reconnecting) your Sungrow inverter with the WINET Dongle allows you to seamlessly track your solar system’s output and efficiency. This dongle is distinct, marked by its 3 lights labeled “RUN”, “WLAN”, and “LAN”. It’s crucial to follow the specific connection steps for the WINET Dongle to ensure you’re accessing accurate, real-time data from your solar installation.
Note: If your dongle displays lights labeled “RUN”, “COM”, and “NET”, you might be looking at the WLAN Dongle. For instructions on connecting the WLAN Dongle, please check out our WLAN Connection Guide. You can also download this guide as a PDF here.
