Fronius is highly regarded in the solar world and generally considered the world’s leading string solar inverter manufacturer. This reputation is not based on sales volume, but service, quality and most importantly reliability. With the solar inverter being the most complex component in any solar systems, it is also the part most likely to develop problems. Inverter faults can be extremely frustrating for installers and customers alike and often result in complete system shutdown, hence why reliability is crucial.
All Fronius solar inverters are engineered, designed and manufactured in Austria. With over half a century of experience in inverter (welder) design and manufacturing it’s not surprising Fronius is considered an industry leader in power conversion equipment. Fronius’s history in designing high performance welding inverters provided the ideal background for moving into the solar inverter production over two decades ago with the first Fronius solar inverter released in 1994.
Fronius continued to develop a number of solar inverters but wasn’t until the release of the snap-in inverter (snapINverter) range in 2012 that Fronius really created a stir and quickly developed a strong following around the world. Up until this point SMA was widely regarded as the industry leader. SMA experienced some issues during the transition to the new generation AV series inverters and lost a lot of ground to Fronius. However, they are one of the few manufacturers which can still compete with Fronius on quality and reliability.
