Integrated data communication
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.
SuperFlex Design
The Fronius SuperFlex Design is an ingenious combination of technical performance attributes that make designing your PV system not only extremely simple, but also incredibly flexible. The key performance factors of the SuperFlex Design are two MPP trackers, together with a high system voltage and wide DC input voltage range. Every DC input, and therefore every MPP tracker, is able to accommodate the entire nominal output of the inverter. Regardless of whether the inverter has to cope with different roof orientations, shading of one or two strings, or the use of residual modules: a Fronius inverter featuring integrated SuperFlex Design will satisfy every conceivable operational PV system planning scenario using just a single inverter model.
Dynamic Peak Manager
The Dynamic Peak Manager is a new MPP tracking algorithm that dynamically adapts its behaviour when searching for the optimal operating point. Its 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.
Multi Flow Technology
Using Multi Flow Technology, different DC and AC energy flows are possible in parallel. On the one hand, this allows energy from the modules and from the battery to be made available for domestic use at the same time. However, it is also possible for the energy from the modules to be simultaneously fed into the battery and the in-house network. Furthermore, not only can the battery be charged from the DC side, but also from the AC side (for example from existing PV systems or other energy sources, such as a wind turbine). This means the inverter is also suitable for AC-coupled retrofitting. The inverter manages these energy flows in such a way that the highest possible degree of self-sufficiency is achieved.
Full Backup
With the full backup option, the entire household, i.e. 1 phase as well as 3 phase devices, can be supplied with electricity in the event of a grid outage. For Full Backup, a battery and a switching device for safe grid disconnection are required in addition to the inverter.
PV Point
The integrated basic grid back-up - a socket that is supplied with power during power outages - ensures that important loads can conitunue to operate should the power fail.
