Best 3-phase solar inverters for commercial or residential usages. 

Fronius is widely considered a leading solar inverter manufacturer. When you sum it up, the reasons are pretty simple – high build quality, proven performance and reliability from an experienced manufacturer.

Clean Energy Review

In 2019, the Fronius Symo ranked as a top performer in the following tests: High Temperature Operation, Transient Response, Ground and Arc Fault.

A unique aspect about Fronius inverters is the SnapINverter technology. It’s a standardised wall mounted bracket with the inverter on a hinge system. This enables easy access for servicing as the inverter opens like a car boot, without needing to be removed from the wall.

Fronius has a solid history and an impressive Austrian manufacturing facility. Austrian perfectionism shines through in the build of their inverter.

The Fronius Primo lines up every version you would want, crowned by the versatile 5kW Primo SC. While the smaller Fronius Symo can be restrictive, those restrictions can be overcome by using a 10kW Fronius Symo. Fronius Solar Web is the best and getting better, and the smart meter is the icing on the cake.
