/ We are the first inverter manufacturer to offer a data communication package with fully integrated datalogging, WLAN, Ethernet, energy management, web server and a range of interfaces. The inverter is connected to the internet by network cable or WLAN - without additional cabling - and grants you the perfect overview of how the PV system is operating. Connection to third-party components is provided by means of interfaces such as Modbus TCP SunSpec, Modbus RTU SunSpec or Fronius Solar API (JSON). The open interfaces can also be operated in parallel to the Fronius Solar.web.
/ The Fronius Datamanager sends system values directly to the Fronius Solar.web online portal via WLAN

/ The Dynamic Peak Manager is a new MPP tracking algorithm that dynamically adapts its behaviour when searching for the optimal operating point. The special feature is that the Dynamic Peak Manager automatically checks the entire characteristic curve on a regular basis and finds the global Maximum Power Point (GMPP), even in partial shade.

/ With conventional MPP trackers it is difficult to determine the global Maximum Power Point (GMPP). Often the GMPP is not detected because the tracker has wrongly identified the local Maximum Power Point (LMPP) as the maximum for the entire characteristic. The Dynamic Peak Manager always finds the global maximum because it regularly checks the entire characteristic.
