SnapINverter Primo – inverter for residential solar

Primo SnapINverter

for Residential Solar

The inverter generation for maximum safety, reliability & ROI

The Fronius Primo inverters are ideal for homes.

With their easy installation, high reliability, and innovative feature set, the Primo inverters provide maximum safety, reliability, and highest energy yield even on complex roofs of shaded systems – giving customers the best return on their solar investment. Power categories from 3.8 kW to 15.0 kW cover a wide range of singlephase applications and make the Primo the best choice.

Easy installation & fast service

The SnapINverter technology makes for safe and easy installation of the inverters. This innovative mounting system allows for inverter installation in 15 minutes or less.

Fronius Primo inverters are incredibly easy to service and ready for pro-active service solutions. Thanks to the inverter’s field-serviceability, reliability and low component count, Fronius Solutions Partners can solve most service issues with just one truck roll to the site. This means minimum time and cost for you and maximum yield for system owners.

High reliability and field-serviceability for less truck rolls

No roof left behind: design flexibility & shade mitigation

Fronius SuperFlex Design gives you the ability to choose the right inverter for any application, from small single phase residential systems to large three phase commercial systems, from multiple roof angles to specific module counts for carports and trackers – Fronius has you covered. Once you have learned how to design with one Fronius inverter, the rest of the product line will be intuitive thanks to a similar design philosophy.

With Fronius SuperFlex Design, you can design systems from incredibly low start-up voltages (as low as 80V or three modules) all the way up to the maximum DC voltage allowed by the code. The large Primo inverters, from 10 to 15 kW, allow for 1,000V applications, which is an attractive option for systems on non-dwellings.

Multiple power point trackers (MPPT) allow for different module orientations or tilts, no matter if it’s a simple east/west design with two symmetric arrays, an asymmetric design with a small sub-array, or a partly shaded system. Simply split the system among the independent trackers as needed, from a 50/50 split all the way to a 33/66 split.

More about SuperFlex Design

The Fronius Primo line comes with a smart shade mitigation feature: The Fronius Dynamic Peak Manager (DPM) is an enhanced MPP tracking software that scans the entire I-V curve when searching for the optimal operating point. Usually, a MPP tracker starts looking for the maximum power point at a high voltage, because that’s where usually the peak of the curve lies. However, in a shaded array, the curve turns into an S-shape, where the peak at a high voltage is no longer the maximum power point across the entire curve.

By checking the entire characteristic curve on a regular basis, the DPM finds the global Maximum Power Point (GMPP) for partially shaded arrays. As with many other technologies, software is replacing clunky hardware with smarter and more integrated solutions.
