Fronius Datamanager 2.0 Box WLAN 4,240,125

The Fronius Datamanager 2.0 4240125 is an integrated WLAN datalogger and communications platform designed to connect compatible Fronius inverters with monitoring, control, and third-party energy management systems. It serves as the communications center of a Fronius PV installation, transmitting system operating data directly to the Fronius Solar.web online monitoring platform when connected to the internet through LAN or WLAN.

With an integrated web server, the Datamanager allows local system monitoring and configuration through a dedicated website. Its built-in communication interfaces include Ethernet, WLAN, RS422, RS485, digital inputs, and digital inputs/outputs, providing flexible options for PV monitoring, load management, meter communication, and external control.

The Datamanager 2.0 also incorporates Modbus RTU SunSpec, Modbus TCP SunSpec, and the Fronius Solar API (JSON), allowing compatible Fronius inverter systems to integrate with third-party platforms while operating in parallel with Fronius Solar.web.
