That&#8217;s because, before 1990, Germany had two capitals and reduced the number of capitals in the German language to compensate. \u00a0<\/p>\r\n<p>The sonnen Evo also has a longer name, the sonnenBatterie Evo, but try not to use that when sending a telegram.<\/p>\r\n<h2>Imported From Germany<\/h2>\r\n<p>The sonnen Evo is imported from Germany. \u00a0Sonnen won&#8217;t assemble it in Adelaide despite all the support they received from the South Australian government to set up a factory here.\u00a0 At the battery launch, sonnen said they would keep that capacity for &#8220;future use&#8221;.<\/p>\r\n<p>I could have told the South Australian Government not to spend valuable resources attempting to set up battery manufacturing in South Australia.\u00a0 (In fact, I think I did.)\u00a0 While they should welcome any solar battery manufacturer who wants to set up shop here in SA, they should treat them the same as any other business.\u00a0 This is because we live in a world of limited resources, and it&#8217;s not possible to give more resources to one business without reducing the resources available for everyone else.\u00a0<\/p>\r\n<p>Governments should stick to what they are good at which is punishing bad things, not promoting good things.\u00a0 This is why the police are in charge of catching bank robbers, and families are in charge of Christmas presents.\u00a0<\/p>\r\n<h2>Components Made All Over<\/h2>\r\n<p>At the launch, they didn&#8217;t say where the sonnenBatterie Evo&#8217;s battery modules are manufactured.\u00a0 But unless they&#8217;ve changed their ways, sonnen will source them from two high-quality battery manufacturers in China<sup class='endnote'><a href='https:\/\/www.solarquotes.com.au\/blog\/sonnen-evo-battery-review\/#en-56453-1' id='enref-56453-1' onclick='return hhEndnotes_show(56453)'>1<\/a><\/sup>.\u00a0 The battery inverter probably also isn&#8217;t made in Germany, but elsewhere in Europe.\u00a0 Other components could come from all over the place.<\/p>\r\n<p>This is not a problem.\u00a0 These days a successful international company can successfully source high-quality components from around the world.\u00a0 Companies that pull it off should be boasting about it, not hiding the fact.<\/p>\r\n<h2>sonnenBatterie Evo Tech Specs<\/h2>\r\n<p>Currently, there&#8217;s no datasheet available for the sonnen Evo.\u00a0<\/p>\r\n<p><em><strong>Update December 7th 2021: <\/strong>The datasheet is available here<\/em>.<\/p>\r\n<p>But sonnen presented slides with technical information at the online launch, and I&#8217;ve scattered them through this article.\u00a0 Here&#8217;s one giving an overview:<\/p>\r\n<p><img decoding=\"async\" class=\"aligncenter wp-image-56607 size-full\" src=\"https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2021\/12\/sonnenevo-overview.jpg\" alt=\"sonnenBatterie Evo technical specifications overview\" width=\"1175\" height=\"541\" srcset=\"https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2021\/12\/sonnenevo-overview.jpg 1175w, https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2021\/12\/sonnenevo-overview-300x138.jpg 300w, https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2021\/12\/sonnenevo-overview-1024x471.jpg 1024w, https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2021\/12\/sonnenevo-overview-768x354.jpg 768w\" sizes=\"(max-width: 1175px) 100vw, 1175px\" \/><\/p>\r\n<h2>Battery Capacity<\/h2>\r\n<p>The battery has a total (or nominal) capacity of 11 kilowatt-hours.\u00a0 But to protect it from capacity loss, its maximum depth-of-discharge is around 91%.\u00a0 This makes its usable storage capacity 10 kilowatt-hours.\u00a0 It should stay reasonably close to that amount within its warranty period, as sonnen promises it will maintain at least 80% of its original capacity.\u00a0<\/p>\r\n<p>If more storage is desired, up to three sonnen Evos can be used for a total of 30 kilowatt-hours of usable storage when new.\u00a0 It&#8217;s possible to add even more if a device from <a href=\"https:\/\/www.solarquotes.com.au\/blog\/switchdin-award-mb1736\/\">SwitchDin<\/a> or another manufacturer is used to manage them.\u00a0<\/p>\r\n<p><em><strong>Update December 7th 2021:<\/strong><\/em> <em>Sonnen says it&#8217;s not necessary to use SwitchDin to go over 30 kilowatt-hours of storage, but it can provide benefits.<\/em><\/p>\r\n<h2>Evo Battery Modules &amp;

question.\u00a0<\/p>\r\n<p>In the latest <a href=\"https:\/\/www.solarquotes.com.au\/blog\/home-battery-testing-results\/\">report from the Canberra Battery Test Centre<\/a>, the sonnen Eco was found to have a round trip efficiency of about 80%.\u00a0 The sonnen Evo may do better than this but, unless I hear otherwise from Sonnen, I would not expect it to be above 85%.<\/p>\r\n<h2>Operating Temperature<\/h2>\r\n<p>The sonnen Evo&#8217;s operating temperature was given as -10\u00baC to 50\u00baC.\u00a0 This is a good range for Australia.\u00a0 Some batteries conk out at 45\u00baC, which is a problem because severe heatwaves are when power is needed most.\u00a0 So far, no Australian capital has ever hit 50 degrees, but it may only be a few years before this changes.<\/p>\r\n<h2>Noise<\/h2>\r\n<p>Sonnen gave no information on noise output.\u00a0 The sonnen Evo has cooling fans, so I don&#8217;t expect it to be completely silent when they&#8217;re operating.\u00a0 But I do expect it to be fairly quiet.\u00a0 After all, there are a lot of sonnenBatteries inside homes. \u00a0\u00a0<\/p>\r\n<p>The cooling fans are claimed to last 60,000 hours.\u00a0 As they may only be used a few hours a day, if that&#8217;s true, they should have no problem reaching the end of their warranty.\u00a0<\/p>\r\n<h2>Outdoors Installation<\/h2>\r\n<p>The system&#8217;s Ingress Protection rating is IP56 which makes it suitable for outdoors installation.\u00a0 This rating means it&#8217;s able to resist strong jets of water.\u00a0 I definitely don&#8217;t recommend hosing it down, but if someone did do that, both the hoser and the hosee should be fine.\u00a0<\/p>\r\n<p>This IP rating is a big improvement on sonnen&#8217;s previous batteries, which had to be installed indoors or in a separate expensive, industrial, steel cabinet.<\/p>\r\n<h2>EVO Battery Dimensions And Weight<\/h2>\r\n<p>The image below gives the sonnenBatterie

batteries, where backup capability was an expensive additional extra, every sonnen Evo has backup built-in.\u00a0 It can supply 5 kilowatts of continuous power during a blackout, the same as in normal use.\u00a0<\/p>\r\n<p>But it will only be able to charge the battery in a blackout using solar power if the solar inverter is 6 kilowatts or less on the same phase as the sonnen Evo. \u00a0<\/p>\r\n<p>The battery has a black start capability that you can use during a blackout (if you have 6 kilowatts or less of solar inverter capacity on the backup phase).\u00a0 If the battery is flat, and the panels are producing enough power, a button on the unit can be pressed that will cause the battery to start charging.<\/p>\r\n<p>When a blackout occurs, the change over to battery backup won&#8217;t be instantaneous.\u00a0 Sonnen said the delay should be under a second.\u00a0<\/p>\r\n<p><img decoding=\"async\" class=\"aligncenter wp-image-56556 size-full\"
