Overview
The Smart USB-WLAN Adapter (WLAN module for short) is a module that can connect to the USB port on a PV device to perform local maintenance for the device over the LLAN module and a mobile phone app. For details about the applicable PV device models and version mappings, see the FusionSolar App and SUN2000 App User Manual. This document describes how to use the WLAN module by using the inverter as an example.
Description for Use
-
Before using the WLAN module, ensure that the device connecting to it has been powered on.
-
When you use the WLAN module to implement the communication between the SUN2000 app and the device, ensure that
one mobile phone connects to only one device. -
