The ideal solution for every roof

Thanks to the SuperFlex design with multi-MPPT concept and a wide range of input voltages, even the most complex system designs pose no problem at all for the Fronius Verto. The new inverter also offers maximum flexibility during installation. It can be installed wall-mounted or flat. When selecting the modules, you can choose from a wide range of options. Thanks to four high-current MPPTs (28 A per string and MPPT), it is also possible to use high-current modules without any problems.

Safety without additional components

Safety plays a central role in the Fronius Verto. It is supplied as standard optionally with a type 2 surge protection device (SPD) on the AC and DC side, or with a type 1+2 SPD on the AC and DC side. An Arc Fault Circuit Interrupter (AFCI), which protects the photovoltaic system from arcs, is also integrated into the Fronius Verto ex works. This means that the Fronius Verto guarantees the highest safety standards even in its basic configuration without any additional accessories. Your customers’ data is also well protected with us. This is ensured by our certified information security system and our servers and cloud storage in Europe.

Designed for maximum convenience during installation

With its spacious and well-protected connection area, the Fronius Verto offers installers plenty of space to work quickly and comfortably. Its housing is designed to allow easy installation with a large AC connection area, MC4 plugs, and mounting bracket. With a 4 to 35 mm2 clamping area, a wide variety of cable types can be used as required.

Energy sector integration made easy

With its open interfaces, the Fronius Verto enables easy integration of compatible charging stations or heat pumps such as the Fronius Wattpilot and the Fronius Ohmpilot. It is also possible to integrate third-party products via Modbus RTU, Modbus TCP, or Solar API without any problems.

Sustainable quality

When manufacturing Fronius products, we always operate according to the principle “Designed and produced with sustainability in mind”. We attach great importance to the conscious use of resources, and use recycled and reusable materials whenever possible. Thanks to active cooling of the power electronics, the Fronius Verto has a particularly long service life. The SPDs can also be replaced on site, saving time and resources.
