SHERIDAN, WYOMING - November 28, 2025 - Fronius is expanding its renewable energy portfolio with the new Verto inverter family, positioning Verto and the hybrid Verto Plus as highly flexible solutions for agricultural businesses, commercial sites and single- and multi-family homes that need robust, future-proof PV system design and reliable backup power.
Flexible PV Design for Complex Rooftops and Mixed Module Layouts
At the core of the launch is the Fronius Verto, a high-performance inverter designed to cope with real-world installation challenges. Whether installers are working on complex roof structures, combining different module orientations or integrating various module types, the Verto is engineered to maintain efficiency and stability.
This flexibility allows EPCs and installers to:
- Optimize self-consumption on constrained or shaded roofs.
- Retrofit and extend existing PV systems without redesigning the entire plant.
- Mix module technologies where needed while keeping performance under control.
As a result, the Verto becomes a strong fit not only for new PV projects but also for the systematic expansion of existing energy systems in both residential and commercial environments.
Hybrid Verto Plus and Reserva Storage for 24/7 Energy Availability
For customers targeting maximum self-sufficiency, Fronius pairs the Verto Plus hybrid inverter with the Reserva battery storage system. This combination is aimed at households and businesses that need reliable power around the clock, even under demanding load profiles.
With Verto Plus and Reserva, installers can design systems that:
- Cover large consumers such as heat pumps, refrigeration units or machinery.
- Maintain operations during grid interruptions through full three-phase backup.
- Support both household and business critical loads in a single integrated design.
The three-phase emergency power supply, implemented via the Fronius Backup Controller or Backup Switch, keeps entire operations running safely in the event of a power outage. The Backup Power Boost function can provide short-term additional power when high startup currents or peak loads occur, helping operators bridge critical situations without sacrificing uptime.
End-to-End System Efficiency with Scalable Storage
The Verto Plus and Reserva storage are designed as a tightly integrated system to minimize conversion losses and improve overall energy yield. In practice, this means higher usable storage capacity and better economics for owners over the lifetime of the system.
The Reserva battery offers flexible capacity options between 6.3 and 15.8 kWh, giving installers scope to right-size storage for different use cases, from single-family homes to small businesses and farm operations. Because the components are designed to work seamlessly together, configuration and commissioning time can be reduced, which is a tangible benefit for installation partners in a competitive market.
Built-In Protection and Cybersecurity for Long-Term Operation
Fronius also places strong emphasis on safety and risk mitigation. The Verto features integrated and replaceable AC and DC surge protection modules, reducing the impact of overvoltage events and simplifying maintenance. Automatic arc fault detection (AFCI) adds another layer of protection against electrical faults that could otherwise lead to system damage or downtime.
On the data side, Fronius systems are engineered to meet strict European quality and safety standards. Plant and customer data are hosted on Fronius servers and cloud storage located in Europe and secured through an ISO 27001-certified information security management system. This is increasingly important for installers and project developers who must address cybersecurity and data protection requirements alongside energy performance.
Service, Support and a Future-Proof European Energy Platform
Beyond the hardware, Fronius underpins its Verto platform with established service and support structures. The company's well-known service and partner network is designed to support both installers and system owners over the long term, from planning and commissioning to troubleshooting and upgrades.
For European renewable energy players, the Verto and Verto Plus line-up offers a way to:
- Standardize on a scalable inverter and storage platform across different project sizes.
- Address stringent European safety and data regulations with a single vendor solution.
- Build future-ready PV and storage systems that support higher self-consumption and resilience.
Fronius positions the Verto family as a secure, efficient and future-proof option for decentralized energy supply "from a single source", enabling installers and operators to offer more robust value propositions to their own customers in the growing European renewable energy market.
