Fronius Energy package

The Fronius Symo Hybrid is the heart of the Fronius Energy Package, the storage solution for "24 hours of sunshine". With power classes ranging from 3.0 to 5.0 kVA, this three-phase inverter temporarily stores the excess energy produced in a battery, the "Fronius Solar Battery". By intelligently managing energy flows, multi Flow Technology enables AC and DC coupling storage systems. This is THE solution for 24 hours of sunshine a day, even in the event of a power outage.

The peculiarity in the design of these devices is that the "connection" compartment is separated from the "power" compartment, and are installed separately. The connection area and cables are first mounted to the wall, then accommodate the "power" compartment. This revolutionary assembly system makes installation and maintenance easier. The inverter is simply placed in the wall holder and then secured. It is not necessary to remove the entire inverter for maintenance, but only the power floor. All cables, settings and configurations remain in place.


 Built-in Wi-Fi interface     Built-in Wi-Fi interface

A simple, easy-to-use surveillance system. Thanks to the Fronius Datamanager, Fronius is the first manufacturer of inverters to offer a Wi-Fi interface built into the inverter itself. The inverter is connected to wireless internet and provides a perfect overview of how the photovoltaic installation works.


Open-protocol data transmission     Open-protocol data transmission

It is easy to connect third-party supplier components to Fronius inverters. The standard open Modbus TCP SunSpec protocol is a simple way to establish a data connection to other systems. The protocol is used through the existing Ethernet interface, ensuring reliable communication.


Smart Grid Ready     Smart Grid Ready

Fronius inverters are ready for tomorrow's Smart Grid. The inverters are optimally equipped to meet future technical requirements. A series of smart features, called "Advanced Network Features," are integrated into devices. These are a number of control functions for optimal injection of reactive and active power. These functions are designed for a stable network even when the density of the PV system is very high and prevent unwanted outages with associated yield losses. Fronius inverters therefore help to ensure the performance of PV systems.



The individual storage solution for 24 hours of sunshine.

Fronius' vision of "24 hours of sunshine" represents the future of energy supply, with 100% of our needs covered by renewable energy. The Fronius Symo Hybrid is at the heart of the Fronius Energy Package, the storage solution for "24 hours of sunshine" a day. This three-phase inverter in power classes ranging from 3.0 to 5.0 kW, allows the excess energy of a photovoltaic installation to be stored in a battery, the Fronius Solar Battery. The result is maximum self-consumption and energy independence. During hours of low production or in the absence of production, the backup power function allows the home to be powered even in the event of a power outage of the public electricity grid. Using the built-in WLAN and Ethernet web server with graphical interface, it is possible to get a perfect configuration and visualization of the installation. In addition, the DC coupling of the battery ensures maximum efficiency of the entire system.
