Click here\u00a0for lots of <a href=\"https:\/\/www.solarquotes.com.au\/inverters\/sungrow-review.html\">Customer Reviews of Sungrow Inverters<\/a> to see how they have performed in Australian homes over the last few years.<\/p>\n<p>If you are considering buying a Sungrow Inverter over an SMA inverter &#8211; then you should also check out <a href=\"https:\/\/www.solarquotes.com.au\/inverters\/sma-review.html\">customers&#8217; SMA\u00a0reviews<\/a>. You&#8217;ll see that, in practice, SMA inverters are more reliable. This is to be expected, since SMA are double the price of a Sungrow!<\/p>\n<p><strong>Now back to the post&#8230;<\/strong><\/p>\n<p>Yesterday I received my latest issue of the solar industry bible, <a title=\"Photon International Magazine\" href=\"http:\/\/photon-magazine.com\/\" target=\"_blank\">Photon International\u00a0<\/a>\u00a0via airmail all the way from Germany. Whilst many people may get excited by the latest issue of Top Gear Australia magazine or Better Homes &amp; Gardens, I&#8217;m one of those odd people that gets my kicks looking through the latest solar panel and inverter specs.<\/p>\n<p><!--more-->One of the really useful parts of the magazine is the inverter reviews. These guys have a lab in Germany where they can torture test the latest inverters and give them a grade from A to F , so the rest of us can skip all the graphs and datasets and simply decide if the inverter is any good or not.<\/p>\n<p>They typically test the efficiency of the inverter under lots of different scenarios, plot the <a href=\"https:\/\/www.solarquotes.com.au\/blog\/two-reasons-you-must-look-at-efficiency-curves-when-choosing-your-solar-inverter\/\" target=\"_blank\">inverter efficiency curves<\/a>\u00a0look for hotspots with thermal imaging cameras, to see if they are prone to early failure, etc, etc. Let&#8217;s just say that these German dudes know how to do a proper test!<\/p>\n<p>In this month&#8217;s issue they test 2 inverters from German companies and one 100% Chinese Inverter. In the old days of the solar industry (think 2009) the results would have been fairly predictable. The German inverters would have got great marks and the Chinese inverter would have got a &#8220;Must try harder&#8221; comment on its scorecard.<\/p>\n<p><strong>How times have changed!<\/strong><\/p>\n<p>Lets have a look at the results in the Feb 2011 issue:<\/p>\n<p><strong>Inverter 1: Effekta ES5000 4.6kW &#8211; German Company &#8211; Made in Taiwan<\/strong><\/p>\n<p>The first time Photon Magazine tested this inverter they gave it a Grade F &#8211; bottom marks. It only managed 92.2% efficiency in strong sunlight. That&#8217;s apalling! The review in this month&#8217;s issue was for the same inverter with a new version of the German designed software. They got the efficiency up to 94.8%, but that still only got it a C grade.<\/p>\n<p><strong>Inverter 2 : SMA Sunny Boy SB 3000HF-30 &#8211; Made in Germany<\/strong><\/p>\n<p>SMA is the market leader in solar inverters and their quality of manufacture is always top notch. So how did this brand new, high frequency, transformer based model rate in the test?<\/p>\n<p>It scored a C grade in medium sunlight and a B grade in strong sun. It got a measured efficiency of 95.2% in strong sun.<\/p>\n<p><strong>Inverter 3: SunGrow Sun Access SG15TKL &#8211; Engineered and Made in China<\/strong><\/p>\n<p>This inverter scored an A grade in all categories tested, they measured an efficiency of 97.0% at high irradiation. They praised its quality of construction too.<\/p>\n<p>The intro to the review says:<\/p>\n<blockquote><p>&#8220;Manufacturing reliable PV Inverters doesn&#8217;t require the use of witchcraft. Those who get the hang of it usually come up with a whole series of solid, sound devices.&#8221;<\/p><\/blockquote>\n<p>How true. Just as manufacturing quality cars is no longer exclusive to Germany, after a sketchy start, many Chinese inverter companies have quickly learned from any mistakes and are now making\u00a0pretty good inverters.<\/p>\n<p><strong>Top tip:<\/strong> Don&#8217;t buy inverters from brand new Chinese manufacturers, they tend to take a couple of years to iron out reliability issues.<\/p>\n<p>Other good inverter manufacturers from China, apart from Sungrow, that are now making high efficiency inverters include: Zeversolar who are now owned by SMA.<\/p>\n<p>So should you dismiss the German made inverters as too expensive, and go for the cheaper Chinese made ones?<\/p>\n<p>Well &#8211; it depends. I would still argue that in terms of multi decade reliability, the German brands like SMA (and the Austrian,\u00a0Fronius)\u00a0 are the safest bet simply because they have been making inverters for decades and can prove their reliability in the real world. So if you want to maximise very chance that your inverter will last for decades &#8211; and you can afford it &#8211; go for a high efficiency &#8220;Top end&#8221; European \u00a0inverter.<\/p>\n<p>However if you are on a budget, like the rest of us, then getting a modern Chinese Solar Inverter\u00a0such as a Sungrow or <a href=\"https:\/\/www.solarquotes.com.au\/inverters\/zeversolar-review.html\">Zeversolar<\/a> is a good option &#8211; just don&#8217;t expect it to last as long as the premium ones.<\/p>\n<p>What has your experience of &#8220;budget&#8221; inverters been? \u00a0Are the expensive brands still worth it? Let rip in the comments below.<\/p>\n<p>[Updated in 2016 to recommend only Zeversolar and Sungrow for Chinese inverters &#8211; due to feedback from installers who&#8217;ve replaced lots of Chinese Growatts and Samils in the 4 years since this article was written]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Note: This post is just one opinion on Sungrow Inverters.
