Selectronic has recently expanded its offering of Selectronic Certified grid-tie inverters to include five models of the Fronius Primo range.

Selectronic and Fronius are aligned in many ways. Not only does the SP PRO integrate seamlessly with Fronius and batteries to give people more choice and flexibility over how their home is powered, but we share the foundation of being a family-run company with a commitment to reliability and customer support.

The Selectronic Certified Fronius Primos are available in power categories from 3.0 to 8.2 kW.

This single-phase device with its innovative SuperFlex Design provides maximum flexibility in system design, while the SnapINverter mounting system makes installation and maintenance easier than ever before.

Whether a Solar Hybrid system or fully off-grid, a Fronius Selectronic Certified inverter will integrate seamlessly with the SP PRO via Managed AC Coupling connectivity.

A simple plug and play connection to the SP PRO makes installation to a battery system very simple.
