The Fronius ecosystem – Sustainable energy from a single source

The Fronius ecosystem combines intelligent products such as inverters, storage solutions, charging solutions, and digital tools to create a holistic energy management system where every component works seamlessly together. Our focus lies on maximum optimization of self-consumption, straightforward control, and full transparency to make sustainable energy not only efficient, but convenient.

To make intelligent energy management a reality, Fronius offers a broad portfolio of solutions for the widest range of requirements. From flexible inverters with a backup power function to energy storage devices and smart tools, Fronius does it all. “Be it for the home, agriculture, or industry, all of our products and solutions are designed to maximize efficiency, safety, and convenience,” explains Harald Scherleitner, CSO, Fronius International GmbH.

Fronius GEN24 & GEN24 Plus: Flexible inverters with backup power
The GEN24 and GEN24 Plus inverters control all energy flows and can be integrated into heating, mobility, and optional battery storage systems. With the PV Point, they offer basic backup power without additional upgrades, are flexible in terms of system design and installation location, and counteract shading with the Dynamic Peak Manager.

Fronius Verto & Verto Plus: Unbeatable flexibility with maximum safety
Specifically developed for agricultural operations, small businesses, large family homes, and multi-unit residential buildings, the powerful Fronius Verto Plus inverter impresses with its outstanding flexibility in system design. When combined with a battery, the Fronius Verto Plus hybrid inverter ensures continuous supply for high-demand loads at all times of the day.

Fronius Argeno: Inverters for commercial systems
Boasting an output of 125 kW, the Fronius Argeno gets the most out of commercial and industrial photovoltaic systems. With 10 MPP trackers, this powerful unit achieves impressive peak efficiency of up to 99.1%, thereby keeping conversion losses to a minimum.

Fronius Reserva: Energy storage devices for maximum autonomy
The high-voltage battery complements the product range with a powerful energy source for evening, overnight, and during cloudy weather. Using the Fronius Solar.web platform, it is also possible to charge the battery from the grid at the touch of a button if required: a useful feature if a storm is imminent and there’s a significant risk of a power outage. Used in combination with the GEN24 Plus or Verto Plus, the Reserva has the capacity to provide backup power and is also black-start capable, which means that battery charging and discharging can continue even during a grid failure.

Fronius Energy Cost Assistant: Enhanced efficiency and greater control
Users benefit from new, intelligent functions for avoiding feed-in limitations and support for 15-minute tariffs. The Energy Cost Assistant manages the intelligent storage strategy and automatically controls the optimum charging and discharging times for the battery based on the generation and consumption forecast, as well as the current energy prices.

Fronius Wattpilot Flex: Charging on a whole new level
With the “made in Austria” charging solution, Fronius is expanding its e-mobility portfolio by pairing proven technology with innovative new features. The Fronius Wattpilot Flex combines efficiency with elegance: from installation to monitoring, convenience leads the way.

Enhancing cybersecurity
System operators have a clear overview of energy flows, states of charge, and consumption at all times on the Fronius Solar.web platform. Data is stored exclusively on Austrian servers and European clouds, thereby further strengthening cybersecurity and data protection systems.

We are Fronius.

Around 6,700 employees worldwide at the end of 2024, a current export share of 90 percent, and 1,752 active patents: that’s us, that’s Fronius. Founded in 1945 as a regional one-man operation, we are now a global player—a fact that is impressively demonstrated by our 37 international subsidiaries and our network of sales partners in more than 60 countries. And yet, at heart, we are still a family-owned company from Austria, active in the electrical and electronics industry. Fronius Welding continuously revolutionizes welding technology, while Fronius Solar & Energy focuses on making the best possible use of solar energy and optimizing battery charging systems for intralogistics. We have been pursuing a clear goal for 80 years now: researching electricity and putting it to efficient use as the fuel of the future. We develop products and solutions for a future worth living in, offering our customers an all-in-one package in the process: from advance planning and consulting to ongoing monitoring and services tailored to their specific needs. We are innovative. We are curious. We are Fronius.
