Fronius Verto & Verto Plus: Best for businesses

Fronius Verto: Flexible inverter for commercial photovoltaic systems

Specially developed for agricultural and small businesses as well as larger family homes and apartment buildings, this powerful inverter impresses with maximum flexibility in system design. Complex roof designs, varying module orientations and slopes, and even mixed module types are handled with ease. Combined, these advantages make the Fronius Verto the ideal choice for setting up a large-scale PV installations and future system expansion.

Fronius Verto Plus: Hybrid inverter with reliable backup power supply

When combined with a battery storage system, the reliable Fronius Verto Plus hybrid inverter not only increases self-consumption in households and businesses but also ensures large loads are reliably supplied with power around the clock. During power failures, the advanced three-phase backup power supply* steps in to deliver dependable energy for the entire business. What’s more, the Backup Power Boost function in backup power mode offers the option of temporarily increasing the output power. Critical processes continue operating without interruption, along with essential equipment such as heat pumps, cooling units, ventilation systems, and commercial machinery.

*Only available in combination with the Fronius Verto Plus, a battery storage system, and a grid switching device.

Highlights

High flexibility for system planning

As flexible as your requirements. Featuring an innovative multi-MPPT concept built around high-current MPPTs, the Fronius Verto always delivers maximum efficiency, even with complex roof and module orientations. Third-party components are integrated with ease thanks to open interfaces.

Maximum output, optimum yields

Even if your system is partly shaded, you still enjoy optimum yields with the Dynamic Peak Manager. Reducing potential energy losses to a minimum, our solution’s intelligent shade management function gets the best out of every PV system—and comes integrated in the Fronius Verto as standard.

Integrated arc and surge protection

The Fronius Verto is equipped with an integrated and replaceable AC and DC surge protection device to give your system reliable protection without any additional components. The arc fault circuit interrupter (AFCI) takes it a step further by providing additional protection against the risk of fire.
