About This Product

The Fronius 25kW VERTO 3 Phase Solar Inverter 3MPPT IP66 With LAN & WIFI is a 25 kW three-phase grid-connected solar inverter designed for larger commercial, agricultural and multi-residential PV systems. It provides three independent MPPT trackers, allowing an installer to manage separate PV array orientations or roof sections while maintaining independent maximum power point tracking. The inverter supports a maximum PV generator capacity of 37.5 kWp and an MPPT operating range of 150-870 V. Fronius includes integrated communications for system commissioning, monitoring and energy management, with LAN and WiFi connectivity for connection to Fronius Solar.web and compatible network services. Its IP66 enclosure allows installation in suitable indoor or outdoor locations.

Who This Product Suits

The Fronius VERTO is suited to three-phase commercial and larger-scale solar installations requiring a 25 kW inverter with flexible PV input management. The three MPPT trackers are particularly useful where panels need to be divided across different roof orientations, pitches or sections with different operating conditions. It is a practical choice for commercial buildings, workshops, agricultural properties, apartment buildings and other sites where network monitoring and remote system visibility are required. The inverter is intended for professionally designed and installed three-phase grid-connected PV systems.

Specifications Explained

This Fronius VERTO has a rated AC output of 25 kW and a maximum apparent output of 25 kVA. Its three MPPT trackers provide independent solar array tracking, with an MPPT voltage range of 150-870 V and a nominal DC input voltage of 620 V. Maximum usable input current is 28 A per string, making the inverter suitable for modern higher-current PV modules when the array is correctly designed. Maximum supported PV generator capacity is 37.5 kWp, providing scope for DC oversizing where appropriate for the installation. Maximum PV-to-grid efficiency is 98.56%. IP66 protection, active cooling and integrated LAN and WiFi communications support commercial installations where reliable operation and remote monitoring are important.

Summary

The Fronius VERTO is a flexible 25 kW three-phase inverter for commercial and larger PV installations. Its combination of three MPPT trackers, 150-870 V MPPT range, support for up to 37.5 kWp of PV capacity, IP66 protection and integrated LAN and WiFi gives installers a practical platform for systems with multiple array sections and ongoing online monitoring. Fronius Solar.web compatibility also provides a straightforward way for installers and system owners to monitor production and operating performance.

Further Information From The Manufacturer

The flexible inverter for small businesses & apartment buildings

Thanks to its multi-MPPT concept with four high-current MPPTs, a wide input voltage range, and innovative shading management, it is also ideally suited to complex system designs. Whether you are installing a new PV system or expanding an existing one, the Fronius Verto can handle different module orientations and slopes, or a combination of different module types in one system.
The Fronius Verto guarantees the highest safety standards with an integrated SPD type 2 on the AC side and a SPD type 1+2 on the DC side. Fronius Arc Guard (AFCI), which protects the photovoltaic system from arcs, is also integrated ex works into the inverter. Our servers and cloud storage in Europe also provide optimum protection for
personal data at Fronius at all times.
