SnapINverter technologyThe SnapINverter generation of inverters features a simple, standardised mounting system, making installation and maintenance easier than ever. A special feature in the design of the device is that the connection area is separate from the power stage set compartment, with both being installed separately. The remarkably light connection area and all its cabling is fitted to the wall first, followed by the power stage set. The innovative hinged system makes installation and servicing extremely user-friendly. The inverter is simply placed in the wall bracket and then secured. This means that it is not necessary to remove the entire inverter for servicing, just the power stage set. All the cabling remains in place.
Integrated data communicationWe 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 DesignThe 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 ManagerThe 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.
Smart Grid ReadyFronius inverters are ready for the Smart Grid of tomorrow. The inverters are optimally equipped to meet the technical requirements of grids in the future. A series of smart functions, known as Advanced Grid Features, are built into the devices. They include a number of control functions for optimum feed-in of reactive power and effective power. These functions are designed to enable stable grid operation even when the PV system density is very high and to prevent unwanted interruptions to feed-in and associated yield losses if grid parameters exceed the thresholds. Fronius inverters therefore help to guarantee the yield of a PV system. Furthermore, where feed-in limits are imposed, Fronius inverters can provide dynamic feed-in control with self-consumption taken into account. Just connect the meter and set the feed-in limit!
Zero feed-inToday, an increasing number of grid operators in various countries are stipulating a PV power feed-in limit as a precondition before a system is connected to the grid. With dynamic power reduction, Fronius is offering a solution for optimum feed-in management. The Inverter supplies the household consumers with energy first and then reduces the system Output to the maximum energy feed-in permitted by the grid operator. With Fronius inverters, zero feed-in is also a possibility thanks to this function, meaning that no PV power is fed into the grid. The relevant requirements of the grid operator can be fulfilled by simply enabling a Setting on the inverter's web interface.
The deliberate design of the Fronius SnapINverter meets great enthusiasm of our insallers and customers.
