Fronius SnapINverter for commercial PV systems

Compact & flexible inverters for economical PV systems

The Fronius SnapINverter series offers several inverters for use in small to medium-sized cost-effective photovoltaic systems.

  • The Fronius Symo is a compact and flexible inverter that can be used to implement even complex system plans.
  • The Fronius Eco enables highly cost-optimized, economically viable PV systems to be implemented.
  • Fronius Symo Advanced and Primo UL cover all requirements that arise in countries with special grid configurations.

Optimizing costs with Fronius inverters

For larger photovoltaic systems it is particularly important to keep the running costs (OPEX) as low as possible and to maximize the yield as much as possible. This results in shorter payback periods and high returns (a higher return on investment) – to the delight of every investor.

By using Fronius inverters, an economically viable PV system can be implemented even under complex system conditions. Thanks to the Superflex Design feature of Fronius Symo, even complex plans with different roof pitches or shading are not a problem.

For simple freestanding or roof systems, you can use the Fronius Eco to design and implement the system in a cost-optimized way.

Combine smart & cost-optimized

A combination of Fronius Symo and Fronius Eco makes sense for most small to medium-sized commercial PV systems. 

This is because small sections of the PV system are usually shaded or have a different orientation

While these more complicated strings are covered by the Fronius Symo, the majority of the PV surface can be covered by the Fronius Eco in a highly cost-optimised manner.

PC board replacement

The option of on-site PC board replacement means that service calls can be carried out quickly and cost-effectively by just one person. This means that in most cases only individual components need to be replaced, rather than the entire device.

Our Fronius Solar.SOS service app helps ensure that everything runs smoothly. Active participation in the Fronius Partner program is a prerequisite for PC board replacement.
