Fronius Eco Inverter



The innovative hinged system design makes servicing and installation safe, easy and user-friendly. A salient feature of the inverter’s design is that the connection area and the power stage set compartment are set up separately. The inverter is placed in the wall bracket and then secured. Hence it is not necessary to remove the entire system for servicing, only the power stage set is removed, while all the cabling remains in the same place. This feature makes the inverter’s installation and maintenance simple.


Fronius is the first inverter manufacturer to offer a data communication package with fully integrated data logging, WLAN, Ethernet, energy management, web server, and a range of interfaces. The inverter connects to the internet with a network cable or WLAN. That helps the consumer by providing an overview of how the PV system is being operated and can be viewed on Fronius Solar.web.


This design is an effective combination of technical performance attributes that makes the designing of PV systems simple and flexible. The key performance factors of this design are 2 MPP trackers, along with a high system voltage and wide DC input voltage range.


A special feature of Dynamic peak manager is that it automatically checks the entire characteristic curve regularly and finds the global Maximum Power Point (GMPP), even in partial shade.


Fronius inverters are ready for the future’s Smart Grid. These inverters are perfectly equipped to meet the technical requirements of the future grid. Fronius inverters include several control functions for optimum feed-in of reactive and effective power so whenever the system’s density is very high, it prevents unwanted interruptions.


With dynamic power reduction, Fronius is offering a solution for optimum feed-in management. The inverter supplies the consumers’ household with energy first and then it reduces the system output to the maximum energy feed-in permitted by the grid operator.


Active cooling technology relies on the fans of the inverter, which does not only avoids hot spots but also regulates the air circulation inside the inverter, thus keeping the temperature of the power electronics low. It has a positive effect on the service life of the devices, as it optimizes yields and reduces the cost
