Fronius: activities across the globe

Cluster-News: July 2018

Fronius has commissioned 162 inverters for a solar park in Ukraine with a peak capacity of 5 MW. Fronius has supplied around half of the projects implemented so far in the new programme of the Chilean government for public buildings. The company now also has a branch in Ukraine and Tatabánya (Hungary) and offers consulting and service programmes on site. In Iran, Fronius and its local service partner support private and commercial plant operators with easy-to-install inverters. The subsidiary "Fronius do Brasil" has branches in the states of Minas Gerais, Paraná, Amazonas, Sao Paulo and Rio Grande do Sul.

Fronius: PV instead of nuclear power & 25 years of solar energy

Cluster-News: January 2018

Fronius installed inverters on the site of the planned Zwentendorf nuclear power plant (which never went into operation). PV panels with a total surface of 3,700 m² were installed and 43 Fronius IG Plus inverters. On the occasion of its 25th anniversary, Fronius Solar Energy expanded its portfolio with, among others, the consumption regulator Fronius Ohmpilot. This product enables the intelligent regulation of heating elements in boilers and buffer storage tanks and thus use excess PV-electricity to heat water.

Fronius Energy Package Powerwall

Cluster-News: November 2016

The Fronius Energy Package Powerwall, developed in close collaboration with Tesla Energy, allows the storage of on-site generated PV electricity. When little or no electricity is generated by the PV-system, the owner can access and use the stored electricity in the Powerwall. The storage solution enables an increase of the self-consumption ratio. Fronius was awarded the "Energy Genius" innovation award for its "Energy Package" system.

Fronius: Partnership with Victron

Cluster-News: November 2016

Fronius and Victron Energy have synchronised parts of their product lines. The inverter chargers and charging controllers of the Dutch company permit PV-generated electricity to be temporarily stored in batteries. This enables a grid-independent, stable and constant supply of PV-electricity to small apartment buildings. This system was first installed in Kenya in summer.
Fronius is expanding its presence in the growing American market with a new branch office in the San Francisco Bay Area that is dedicated to product management, research & development and sales.

Fronius: PV Genset solution

Cluster-News: November 2015

Diesel generators are often used in remote areas. The PV-Genset Solution developed by Fronius supports the combination of diesel generators and PV systems. Combining these systems brings technical, environmental and economic benefits. The new PV management system is able to control such combined-systems as a whole by integrating information from the inverters and load measurements (as well as measurements from the diesel generator if required).

Fronius 2015 novelties

Cluster-News: May 2015

The "Fronius Energy Package", a storage solution for "24 hours of sun", consists of the inverter Fronius Symo Hybrid, the Fronius Solar Battery and the Fronius Smart Meters. Thanks to the Fronius Primo, the youngest member of the SnapINverter family, a single-phase unit now joins its three-phase counterpart, the Fronius Symo, on the market. Fronius also modernises older inverters, which can be replaced by Fronius devices.

Fronius: Active Energy Tower & prototype of a hybrid inverter

Cluster-News: July 2013

Fronius opened a new building, the Active Energy Tower, in Wels. Due to its active energy design, the use of photovoltaics and geothermal energy sources, the building is heated and cooled without generating any CO2 emissions. Fronius presented its latest developments at the Intersolar in Munich in June 2013. The highlight on their 512 m² stand was a prototype of the Fronius hybrid inverter which is able to temporarily store self-generated electricity with the help of batteries. It will be available in 2014.

Fronius goes Brazil

Cluster-News: July 2013

Recently, Fronius International opened a Solar Electronics subsidiary in Sao Paulo. The market for PV in Brazil has enormous potential. The focus in Brazil is on small systems up to 5 kW for households and medium-sized systems up to 1 MW. The first projects are already connected to the grid. Fronius is supplying the string inverter for the largest photovoltaics project in Brazil. 50 Fronius IG Plus 120 inverters support the 1 MW system in Tanquinho.
