TECHNOLOGIES

FRONIUS AP
This is a program that allows the installer to update the Fronius product via Solar.web without any additional hardware. Fronius UP offers unique, new and innovative opportunities to expand Fronius products with new functions according to customer needs at any time. This ensures maximum flexibility and future reliability.

INTEGRATED DATA COMMUNICATION
We are the first inverter manufacturer to offer a data communications package with fully integrated data logging, WLAN, Ethernet, energy management, web server and a range of interfaces. The inverter connects to the Internet via a network cable or WLAN - without additional cables - and gives you a perfect overview of the operation of the photovoltaic system. Connection to third-party components is carried out via interfaces such as Modbus TCP SunSpec, Modbus RTU SunSpec or Fronius Solar API (JSON). The open interfaces can also be used in parallel with Fronius Solar.web.

DYNAMIC PEAK MANAGER
Dynamic Peak Manager is a new MPP tracking algorithm that dynamically adapts its behavior to find the optimal operating point. Its special feature is that Dynamic Peak Manager automatically checks the entire characteristic curve on a regular basis and finds the global maximum power point (GMPP) even in the penumbra.

MULTI-THREADING TECHNOLOGY
Using Multi Flow technology, parallel flows of DC and AC energy are possible. On the one hand, this makes it possible to obtain energy from the modules and a battery, which at the same time should be available for home use. However, it is also possible to simultaneously supply energy from the modules to the battery and the intra-house network. Moreover, the battery can be charged not only from the DC side, but also from the AC side (for example, from existing photovoltaic systems or other energy sources such as a wind turbine). This means that the inverter is also suitable for retrofitting with an AC connection. The inverter manages these energy flows in such a way that the greatest possible degree of self-sufficiency is achieved.

SUPERFLEX DESIGN
Fronius SuperFlex Design is an ingenious combination of technical features that make designing your photovoltaic system not only extremely simple, but also incredibly flexible. Key to the performance of the SuperFlex design are the two MPP trackers, as well as the high system voltage and wide DC input voltage range. Each DC input and therefore each MPP tracker is capable of delivering the inverter's full rated output power. Whether the inverter has to cope with different roof orientations, the shading of one or two strings or the use of residual modules: the Fronius inverter with With its integrated design, SuperFlex will satisfy every conceivable PV system planning scenario using only one inverter model.

FULL BACKUP
Thanks to the full backup option, the entire house, i.e. both single-phase and three-phase devices, can be supplied with electricity in the event of a power outage.

PV POINT
Built-in core backup—the outlet that receives power during a power outage—ensures that critical loads can continue operating in the event of a power failure.

ACTIVE COOLING
Active cooling technology is based on the use of one or more fans, which not only avoid overheating, but also regulate air circulation inside the inverter, thereby maintaining a low temperature of the power electronics. This has a positive effect on the service life of the devices, optimizes product yield and reduces costs. Fronius includes active cooling standard equipment for all devices.
