Fronius International is an Austrian company with 75+ years of experience in welding, battery charging, and solar electronics. That cross-discipline pedigree shows in their inverters — exceptional thermal management, long mean-time-between-failure, and conservative engineering choices that just keep running. We install Fronius Primo and Symo models for residential and commercial systems where reliability is non-negotiable.
Key Features
Manufactured in Austria with the build quality you expect from European precision engineering. Heavy castings, top-tier components, exhaustive QA.
