The WIFI Plug module is an external data logger used for solar hybrid and stand-alone solar inverters manufactured by MUST. It communicates with the solar inverters via a USB port. The WIFI Plug module monitors the solar system's status and performance in real time, recording and accumulating technical operating parameters. A router is used to control the solar system and facilitate monitoring of the solar inverters, and data can be transmitted to the Must cloud server and presented graphically in dedicated applications, anywhere and anytime. The module is easy to use and supports remote monitoring, debugging, and firmware updates for Must inverters.
