The Fronius Data Manager is the communications center for Fronius inverters for all applications Whenever it is connected to the internet via a LAN or WLAN, the Fronius Data Manager sends the PV system values directly to the Fronius Solar.web online portal. This provides you with an overview of how the system is operating at all times. The Fronius Data Manager enables inverters to be connected directly to the internet via a WLAN. The system and the Data Manager configuration are monitored via the dedicated website on the integrated web server of Fronius Data Manager. The integrated Modbus RTU SunSpec, Modbus TCP SunSpec and Fronius Solar API (JSON, for actual values) interfaces allow Fronius inverters to be seamlessly linked to third-party systems and run in parallel with Fronius Solar.web.
