The Solis S1 WiFi + 4G Stick with SIM is a professional USB data logger designed for compatible Solis S6 inverters. It provides stable and flexible remote monitoring through both WiFi and 4G communication, allowing installers and end users to monitor inverter and plant performance in real time via the SolisCloud platform. The USB version connects directly to the inverter’s external USB communication port and offers a practical solution for residential and commercial PV installations where reliable internet access is essential.

This version is supplied with SIM card and is designed for convenient remote communication without the need for a separate external monitoring device. The logger gives priority to WiFi communication by default and automatically switches to 4G when the WiFi signal is unavailable or unstable. Once WiFi is restored, the device automatically reconnects.

For local commissioning and service access, the logger supports Bluetooth nearby connection, making setup and troubleshooting easier for installers. Configuration can be completed through the SolisCloud APP or web platform, while built-in LED indicators and a RESET button help simplify installation, status checking, and debugging.
