In this Fronius inverter review we’ll go through some of the features of Fronius inverters. We’ll also take a look at the company’s rep and performance in any independent tests.
Fronius Inverters Overview
Fronius is a
German, wait! Austrian company with a pretty decent history. Their original product focus was on battery chargers & welder transformers. They entered the solar inverter market in 1992 and have done pretty well. They haven’t quite entered the domain of their German rival SMA, but their product is good and they have a few “unique” points about them.
Fronius Inverter Models
Fronius have a pretty decent range of inverters on the market including:
- The IG Series (Including IG, IG Plus, IG TL) – The IG are the smaller inverter series, IG plus go up to 12kW in capacity (and have a 2 phase inverter model) and the IG TL is of coarse the “transformerless” model. These are the most common Fronius inverters sold in Aus.
- The Symo Series – These are the 3 phase inverters from Fronius. Their range goes all the way up to 20kW
- The Galvo Series – This inverter series doubles as an energy management system. Cutting edge tech.
- The Agilo Series – These are their “utility” scale inverter series.
- The CL Series – These are another branch of commercial/utility and are expandable modules… Cool.
Why do most of the Fronius inverter series sound like their named after pets from the Herculian era? We don’t know. What we do know is that they host a pretty serious arsenal of nifty inverters.
Independent Test Results
OK this is pretty important. Independent tests are cool because they aren’t biased… Not usually anyway. The 2013 Inverter test by Photon had some pretty good things to say about Fronius too. The 5kW Fronius TL inverter beat the SMA Sunny Boy 5000TL! And it was just behind Growatt’s TL 5kW unit. It got a “B” Grade (as of 2011) and held on at position 50 overall (includes all inverter sizes.
These are very impressive results. Any unit that beats SMA (the god of inverters) is pretty darn snazzy.
Fronius Inverter Review – The Good
So what’s good about the Fronius inverter? Well of course it depends on which model you look at. Overall they have a very impressive setup.
- German made inverters
- Fronius has a background in other electronics technology as well
- They have very aesthetically pleasing (awesome-looking) inverters
- They have features galore and are up-to-date with all the latest energy tech
- They had awesome independent test results in Photon
- Their website looks cool!
Fronius Inverter Review – The Bad
What’s not to love about Fronius? Well the price tag isn’t that lovely. You always pay a few extra dimes for quality, but in some cases, Fronius take the cake and eat it. What am I on about? Well, for example, if you compare the price of 2 single phase SMA inverters with the price of 1 dual-phase Fronius, SMA is cheaper by a few hundred buckeroos.
The other point I thought worth mentioning is although they have USB and wireless functions, it’s not cheap to get a simple monitoring setup!
That’s about it though, if price were no obstacle, it would be a close call trying to decide between the Fronius and the SMA. Given that Fronius had a slightly better Photon result… And SMA has a much longer history, I’d probably give it to SMA.
