For years the West has been a sorry state in solar terms. The only networks in town have draconian 5kW limits on inverters, and it makes the rest of Australia give them side eye. Why do the western weirdos hate sunshine?<\/p>\n\n\n\n

Thanks to Austrian manufacturer Fronius though, there is now a 10kW inverter option available in WA, all you need is a well-trained installer.Fronius has run a 12-month testing program to present a well-researched case to Western Power authorities for using 10kW single-phase inverters.<\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n

What they\u2019ve proven is that a 10kW inverter with a 13.33kW solar array will yield between 32% and 99% more energy, compared to a standard 5kW inverter with 6.6kW solar array.<\/p>\n\n\n\n

The larger array will get to full 5kW output earlier, and continue later into the afternoon, but Western Power\u2019s 5kW limit is basically useless in winter. What\u2019s more beneficial to you and the network is the near doubling of output across the low season.<\/p>\n\n\n\n

When everyone is scratching for energy in winter, your Fronius system is working twice as hard.<\/p>\n\n\n\n

5kW Is Still The Limit, Until It Isn\u2019t<\/h2>\n\n\n\n

Western Power has decided an Absolute Generation Limit1<\/a><\/sup> of 5kW is still in order, but they\u2019ve been persuaded by the boffins at Fronius to allow the 10kW Primo Gen24 to be commissioned via a special manual approval, for which your installer needs training before they apply.<\/p>\n\n\n\n

It\u2019s similar to the Tesla Powerwall 3 \u2014 what could be an 11kW machine is limited to 5kW, so Western Australian commissioning effectively gives you a Powerwall 2\u00bd.<\/p>\n\n\n\n

However Fronius has gone one step better. If you add a battery, the 10kW Gen24 will operate at a full 10kW capacity when there\u2019s a grid outage.<\/p>\n\n\n\n

It\u2019s Not What You Know, But Who<\/h2>\n\n\n\n

Installers in the west have a vital resource with sales engineer Shane Arnold organising the kind of support that quashes problems before they arise. He insists that service issues are raised via the online support tool Fronius SOS, but he\u2019s there on the phone backing it up.<\/p>\n\n\n\n

As an 80-year-old international company, Fronius has excellent web resources, but the sheer volume of documents is equally a curse. Again thanks to Shane and his curated Whatsapp group, Australian installers can find Australian support material without wading through the Italian, Polish or American dross.<\/p>\n\n\n\n

This Isn\u2019t An Advertorial<\/h2>\n\n\n\n

The sceptical reader might wonder, but to be honest, I just like seeing quality products on the wall.<\/p>\n\n\n\n

Cheap customers deserve what they get to some extent, but after years of trouble-free service, I find it a bit disturbing when people are keen on chintzy battery hybrids that can\u2019t talk to legacy equipment.<\/p>\n\n\n\n

I have equally advocated for\u00a0saving good equipment\u00a0from the streams of e-waste we create. Fronius build inverters that are retro-compatible with new network company requirements, so adding more solar doesn\u2019t render them obsolete.<\/p>\n\n\n\n

Roaring Success<\/h2>\n\n\n\n

Yes, I\u2019m a Fronius fanboi\u2026 which is a bit of an in-joke because Fronius inverters perform better as they have fans to keep them cool.<\/p>\n\n\n\n

While some of the Snap-inverter range had two or three fans, which were described by disgruntled customers as roaring jet engines, I preferred to think of them as a statement of purpose. At full noise they were making lots of power.<\/p>\n\n\n\n

Being Left Behind?<\/h2>\n\n\n\n

I\u2019ve spoken to installers who are all in on Sungrow, because they are great products, have a solid history and good support.<\/p>\n\n\n\n

Many really rate GoodWe as a great value proposition with a well-integrated EV charger, something Sungrow has only just released.<\/p>\n\n\n\n

Others are telling me Sigenergy are now the undisputed champion of installation speed, features and aesthetics.<\/p>\n\n\n\n

Still, nobody else I\u2019m aware of is offering a backup supply without a battery, like the Fronius PV Point does.<\/p>\n\n\n\n

Tall Poppy Syndrome<\/h2>\n\n\n\n

I field complaints that Fronius just aren\u2019t leading with innovation anymore, they\u2019ve only got two input channels, they\u2019re too expensive, the BYD batteries aren\u2019t big enough, the WiFi is flakey, the commissioning process is too hard.<\/p>\n\n\n\n

Still when I speak to those running the networks, the people at SAPN, Ausnet, Powercor and the like, they all say the same thing. Fronius are solid and their engineering team is great, \u201cwe don\u2019t have worries with them\u201d (like we do other inverter makers).<\/p>\n\n\n\n

And I have to point out that Fronius doesn\u2019t use the customers for beta testing, nor the installers as donkeys to carry it out.<\/p>\n\n\n\n
