And you thought the election was a shock result…
I have good news. PVEL — a standards testing company — has released a solar inverter scorecard. It describes how a dozen different tests were performed on a variety of inverters and which were the top performers [Read more…]
Spat over inverter review intensifies as SolarEdge go legal.
At 3:15pm on Christmas Eve, when most Australian families were kicking back with a drink and looking forward to at least 2 days with family, friends and no work worries, Mark Cavanagh1, owner of the highly regarded solar installation company, MC Electrical2 received a five page letter from lawyers acting for $1.6 billion Israeli inverter manufacturer, SolarEdge.

There are a few things you need to know if you are getting a 3-phase solar inverter and expect to add a battery later.
I love three-phase solar inverters.
If your home has a three-phase supply and you do not want or need micro-inverters then my recommendation is to use a three-phase solar inverter over a single-phase model. [Read more…]
Huawei were not allowed to bid for the NBN due to spying concerns. But their solar inverters look pretty good.
Huawei is a giant Chinese company and the world’s largest producer of solar inverters going by gigawatts of capacity. [Read more…]
Is your web-connected solar inverter secure?
Note from Finn: Please welcome Willem Westerhof to the SolarQuotes® Blog. Willem is a Hacker, Researcher and IT Specialist who is particularly well known around the world for finding cyber-security holes in popular solar inverters. [Read more…]
Enphase have not got close to the cost reduction targets they set a couple of years ago.
Enphase is an American company that sells microinverters. These are small, fun sized versions of the larger string inverters most solar homes use. They work with individual panels and are either bolted beneath them or, in the case of AC panels, come already attached. [Read more…]
Today Ronald examines the SolarEdge HD Wave inverter. It’s small. But not that small.
It’s An Itsy Bitsy, Teeny Weeny, SolarEdge, HD Wave String Inverter…
SolarEdge, an Israeli company, has produced the HD Wave — the world’s smallest string inverter. By size, this little cracker takes more DC than any inverter out there. Not only that, but it grabs DC, uses its funky HD wave technology on it, and spurts out the AC our homes use with greater efficiency than any thing else on the market. And it’s now available in Australia, starting from a couple of weeks ago. [Read more…]
2 x 5kW SMA Sunny Boy Inverters. One made in China (SMA SB 5.0-1AV-40), one made in Germany (SB5000TL-21). How do they compare?
SMA have released a new single phase inverter. They kept the same joyful name of “Sunny Boy” however the model has changed from what was known as the “dash 21” to the “dash 40”.
But let me tell you a well-known secret about the SMA “dash 40”. The respected German manufacturer is manufacturing these new SMA inverters in China.
Bombshell.
Has this turned the single phase model of SMA inverters into a cheap Chinese inverter? To find out, I bought myself a 5kW Chinese-built SMA “dash 40” and pulled it apart to compare it to the 5kW German made “dash 21”.
In this post, I’ll first look at the external features: the “smart screen”, the Sunny Home Manager, and the inbuilt DC isolator.
Then I’ll look at the internal build quality, and where the different components are manufactured. Finally, we’ll discuss the after sales service and warranty of SMA. [Read more…]
Enphase panel monitoring is a great feature. But some Enphase installers flat out refuse to enable it.
There are many people in this world who enjoy monitoring the output of their rooftop solar systems.
But other people – not so much. For example, I don’t think my parents have checked the output of their system since they got it. My father just looks at the electricity bill every three months and grunts, “Power bill low. Is good.” And then goes back to making stone tools.
But for those who enjoy the heady pleasures of solar system monitoring, modern technology can provide the fix you’re looking for. [Read more…]
Are these 3 little chips all you need to optimise your panels for maximum energy output?
Maxim Integrated is a Californian electronics company that has been going strong for 33 years and has only ever been delisted from the Nasdaq Stock Exchange once. As you may be able to tell from their name, they like to integrate things and have developed a way to optimise the power from individual solar panels using 3 tiny chips embedded in the panel.
