Fronius Symo Hybrid 3.0-3-S

This inverter combines a battery charging system, battery inverter, hybrid inverter, controller and system monitoring solution in one device. With AC power categories ranging from 3.0 to 5.0 kW, the inverter is able to process up to 8.0 kW in order to supply household consumers with energy and to temporarily store surplus energy from a photovoltaic system in a battery storage device. Thanks to an intelligent energy flow management system, the built-in Multi Flow Technology supports simultaneous energy flows in all directions as well as AC-, DC- and AC- & DC coupling of the battery storage. The result: maximum self-consumption and optimum system profitability.


The 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.


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 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.


Fronius 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!


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.


Today, 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.
