So much so that they won &#8220;<a href=\"https:\/\/www.solarquotes.com.au\/blog\/sungrow-battery-installer-view\/\">Best Budget Battery<\/a>&#8221; in our installer choice awards.\u00a0<\/p>\r\n<p>But beyond having a reliable battery, you also want a decent manufacturer warranty so you won&#8217;t have to worry if something goes wrong.\u00a0 For the most part, Sungrow provides this security, and <strong>for the most part, the warranty is good<\/strong> &#8212; except for <strong>one glaring error<\/strong> involving temperature.\u00a0 At least, I assume it&#8217;s an error.\u00a0 If it&#8217;s not, I&#8217;ll take back anything good I&#8217;ve ever said about Sungrow.\u00a0 In fact, I&#8217;ll also take back any neutral statements I&#8217;ve made, leaving only the bad.<\/p>\r\n<p>I&#8217;ll explain how bad weather can &#8212;

as well as a big long rant on their stupid warranty mistake.<\/p>\r\n<h2>Hybrid Inverter Required<\/h2>\r\n<p>The Sungrow battery will require a compatible hybrid inverter and &#8212; for all normal installations &#8212; that will mean a Sungrow hybrid solar inverter.\u00a0 I briefly covered them in my <a href=\"https:\/\/www.solarquotes.com.au\/blog\/sungrow-inverters-deep-dive\/\">deep dive into Sungrow inverters<\/a>.\u00a0 There are two models:<\/p>\r\n<ul>\r\n<li>Single Phase:\u00a0 The 5 or 6kW SH5.0\/6.0RS\u00a0 (<a href=\"https:\/\/info-support.sungrowpower.com\/application\/pdf\/2022\/06\/29\/DS_20220623_SH5.0_6.0RS_Datasheet_V10_EN(AU).pdf\">Datasheet<\/a>)<\/li>\r\n<li>Three Phase:\u00a0 The 5 to 10kW SH5.0\/6.0\/8.0\/10RT (<a href=\"https:\/\/en.sungrowpower.com\/upload\/file\/20210706\/DS_20210703_SH5~10RT_V1.2.1_EN.pdf\">Datasheet<\/a>)<\/li>\r\n<\/ul>\r\n<p>Most homes have single-phase power and so will use an SH5.0RS or SH6.0RS.\u00a0 Homes with three-phase power can choose between using a single-phase or three-phase hybrid inverter.\u00a0 If a three-phase hybrid inverter is used, it can supply three-phase backup power and provide it from a single battery.\u00a0 There&#8217;s no need for three separate batteries as with some setups.<\/p>\r\n<p><a href=\"https:\/\/www.solarquotes.com.au\/inverters\/sungrow-review.html\">Sungrow inverters<\/a> now have <a href=\"https:\/\/www.solarquotes.com.au\/blog\/solar-analytics-monitoring-mb2293\/\">integrated Solar Analytics<\/a>.\u00a0 This means you can get Solar Analytics monitoring without paying for hardware.\u00a0 You will need to pay for a subscription, but I highly recommend it unless you are absolutely skint or you are a &#8220;fire and forget&#8221; type of person and know you&#8217;re unlikely ever to use it.\u00a0<\/p>\r\n<h2>Tip For Filling Your Roof With Solar<\/h2>\r\n<p>Because of the way the <a href=\"https:\/\/www.solarquotes.com.au\/panels\/rebate\/\">financial incentive for solar<\/a> works, it normally only makes sense to install a solar panel capacity that is a maximum of one-third larger than the inverter capacity.\u00a0 But if you get solar and a battery installed simultaneously, it&#8217;s possible to go over this limit &#8212; provided the inverter allows it.<\/p>\r\n<p>A Sungrow single-phase hybrid will allow panel capacity to be over twice its capacity, and the three-phase version will allow it to be 50% more.\u00a0 <strong>More solar panel capacity means more savings<\/strong> and solar energy is unlikely to go to waste if you have a battery.\u00a0<\/p>\r\n<h2>Sungrow Battery &#8212; Energy &amp; Power<\/h2>\r\n<p>The Sungrow battery is made of modules stacked on top of each other.\u00a0 There can be from three to eight of them, each providing up to 3.2kWh of usable storage when new, giving the following storage capacities:<\/p>\r\n<ul>\r\n<li>3 modules:\u00a0 9.6kWh<\/li>\r\n<li>4 modules:\u00a0 12.8kWh<\/li>\r\n<li>5 modules:\u00a0 16kWh<\/li>\r\n<li>6 modules:\u00a0 19.2kWh<\/li>\r\n<li>7 modules:\u00a0 22.4kWh<\/li>\r\n<li>8 modules:\u00a0 25.6kWh<\/li>\r\n<\/ul>\r\n<p>Eight modules will be plenty for all but the most energy-hungry household, but if you still want more&#8230;<\/p>\r\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-73403\" src=\"https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2023\/04\/sgbatwar-moar.jpg\" alt=\"Oliver Twist asking for MOAR!\" width=\"347\" height=\"347\" srcset=\"https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2023\/04\/sgbatwar-moar.jpg 347w, https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2023\/04\/sgbatwar-moar-300x300.jpg 300w, https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2023\/04\/sgbatwar-moar-150x150.jpg 150w, https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2023\/04\/sgbatwar-moar-100x100.jpg 100w\" sizes=\"(max-width: 347px) 100vw, 347px\" \/><\/p>\r\n<p>&#8230;up to four stacks can be connected in parallel, providing over 100kWh of storage.\u00a0<\/p>\r\n<p>The maximum amount of continuous power the battery can provide depends on how many modules are in a stack, ranging from 5.76kW up to 15.36kW.\u00a0 While this amount of power <em>is<\/em> impressive, in practice, it&#8217;s normally limited by the hybrid inverter&#8217;s output.\u00a0 For example, when supplying backup power, a single-phase 5kW Sungrow hybrid inverter will be unable to supply more than 5kW of continuous power.<\/p>\r\n<p>The battery is High Voltage (HV), which is a change from Sungrow&#8217;s older, Low Voltage (LV) battery.\u00a0 This difference is important for installers, but for homeowners, the main difference is that HV batteries have more flexibility in their location.\u00a0 This is important for meeting Australia&#8217;s strict battery safety guidelines.<\/p>\r\n<p>If you want more of the battery&#8217;s technical details, you can <a href=\"https:\/\/info-support.sungrowpower.com\/application\/pdf\/2022\/04\/21\/DS_20220421_SBR096_128_160_192_224_256_Datasheet_V13_EN.pdf\">check out its datasheet<\/a>.<\/p>\r\n<div id=\"attachment_73605\" style=\"width: 860px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" aria-describedby=\"caption-attachment-73605\" class=\"size-full wp-image-73605\" src=\"https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2023\/04\/sgbatwar-batts.jpg\" alt=\"Sungrow batteries with 3, 5, and 8 modules.\" width=\"850\" height=\"509\" srcset=\"https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2023\/04\/sgbatwar-batts.jpg 850w, https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2023\/04\/sgbatwar-batts-300x180.jpg 300w, https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2023\/04\/sgbatwar-batts-768x460.jpg 768w\" sizes=\"(max-width: 850px) 100vw, 850px\" \/><p id=\"caption-attachment-73605\" class=\"wp-caption-text\">Sungrow batteries with three, five, and eight modules.

This will make 40.32MWh become 40,320kWh.<\/p><\/div>\r\n<p>This means the warranty will last a full 10 years for all normal households.\u00a0 Only under unusual circumstances would a home use more storage throughput than permitted.\u00a0 If energy equal to its full usable capacity when new was discharged from the battery every day, it would take the following amounts of time to reach its limit:<\/p>\r\n<ul>\r\n<li>3 modules with 9.6kWh of storage:\u00a0 11.5 years<\/li>\r\n<li>4 modules with 12.8kWh of storage:\u00a0 11.5 years<\/li>\r\n<li>5 modules with 16kWh of storage:\u00a0 11.5 years<\/li>\r\n<li>6 modules with 19.2kWh of storage:\u00a0 11.5 years<\/li>\r\n<li>7 modules with 22.4kWh of storage:\u00a0 11.3 years<\/li>\r\n<li>8 modules with 25.6kWh of storage:\u00a0 11.3 years<\/li>\r\n<\/ul>\r\n<p>As normal households average much less use than this, they are only likely to go over the limit if the battery is part of a VPP that works it hard, or if the owner uses it to buy and sell electricity on the wholesale market (and so often charges it from the grid).\u00a0<\/p>\r\n<p>I expected the amount of energy storage the warranty allows would be constant per module, but if you have more than six it actually drops by 2%.<\/p>\r\n<h2>60% Battery Retention<\/h2>\r\n<p>The warranty promises the battery will retain a minimum of 60% of its original capacity, either for 10 years or until its kilowatt-hour throughput limit is reached.\u00a0 This looks lousy compared to the Tesla Powerwall 2, which promises a minimum of 70% capacity retention.\u00a0 But it&#8217;s not as bad as it seems, because the Sungrow warranty allows for more energy throughput.\u00a0 Comparing them by looking at the amount of stored energy they can provide per kilowatt-hour of original capacity, gives the following: \u00a0<\/p>\r\n<ul>\r\n<li><strong>Tesla Powerwall 2<\/strong>:\u00a0 70% retention after providing 2,800kWh of stored energy.<\/li>\r\n<li><strong>Sungrow Battery<\/strong>:\u00a0 60% retention after providing 4,200kWh of stored energy.<\/li>\r\n<\/ul>\r\n<p>So the Sungrow warranty allows<strong> 50% more energy throughput than the Powerwall<\/strong>&#8216;s at the cost of allowing one-third more capacity deterioration.\u00a0 To me, that looks like a good trade-off.\u00a0 If I only considered their warranties and no other information &#8212; all else equal &#8212; I would <em>expect<\/em> the Sungrow battery capacity to deteriorate slower than the Powerwall 2.\u00a0<\/p>\r\n<h2>What Sungrow Will Do<\/h2>\r\n<p>According to the battery warranty, you can make a claim under the following two conditions:<\/p>\r\n<ul>\r\n<li>If the battery is defective due to material or workmanship for 10 years from installation.<\/li>\r\n<li>The battery can operate but fails to retain at least 60% of its original usable capacity while still under its throughput limit.<\/li>\r\n<\/ul>\r\n<p>Under these circumstances, the warranty says Sungrow will&#8230;<\/p>\r\n<blockquote>\r\n<p>&#8220;&#8230;provide the material (replacement parts or an equivalent replacement) via standard freight and standard service rebates to cover the labour costs of repair.\u00a0 Sungrow guarantees to provide a new or refurbished replacement, at its discretion, which performance is equal or higher than defective product.&#8221;<\/p>\r\n<\/blockquote>\r\n<p>So Sungrow will provide either parts or a replacement and pay for labour.\u00a0 They can replace it with a second-hand refurbished unit, but say its performance will be at least as good as the original.\u00a0<\/p>\r\n<p>Provided Sungrow is still producing this battery model, they don&#8217;t give themselves the option of providing a refund based on how much warranty remains, as some manufacturers do.\u00a0 In my opinion, this is a good thing because these refunds are often miniscule.\u00a0<\/p>\r\n<p>If they are no longer producing it, the warranty says they can replace it with a similar product or refund, &#8220;&#8230;the remaining annually depreciated value of the purchase price of the Products&#8230;&#8221;\u00a0 So, if the battery breaks down after 8 years and they&#8217;ve stopped producing them, it&#8217;s possible they&#8217;ll only refund 20% of what you paid &#8212;

I guarantee it&#8217;s not a deepfake.<\/p><\/div>\r\n<p>So the datasheet says its operating temperature is between -20 and 50\u00b0 but the installation manual &#8212; which must be followed for the warranty to apply &#8212; says the ambient temperature must always be between 0\u00b0 and 45\u00b0.\u00a0<\/p>\r\n<p>I wasn&#8217;t expecting the Sungrow warranty to turn into a load of fetid dingo kidneys, but it managed to pull it off.<\/p>\r\n<p>You can&#8217;t put a good operating temperature range on a datasheet but then say the warranty doesn&#8217;t apply if the product isn&#8217;t kept within a <em>far more restricted range<\/em> that&#8217;s tucked away inside the installation manual.\u00a0 That&#8217;s bloody unacceptable.<\/p>\r\n<h2>The Weather Can Kill Your Warranty<\/h2>\r\n<p>Now if you thought that pile of dingo kidneys was awfully fetid, brace yourself, because it gets worse.<\/p>\r\n<p>The warranty is at the mercy of the weather.<\/p>\r\n<p>The temperatures given in the installation manual aren&#8217;t an operating range.\u00a0 They are ambient air temperatures.\u00a0 If the temperature where the battery is installed goes below zero or above 45\u00b0, then the manual requirements weren&#8217;t followed, and your warranty is void.\u00a0 As batteries are normally installed outside, this is a serious problem.<\/p>\r\n<p>The temperature has dropped below zero in every capital city except Darwin, where freezing is considered to be the point where jelly shots set.\u00a0 Here&#8217;s a list of capital temperatures when they were at their maximum brass monkeys:<\/p>\r\n<ul>\r\n<li>Brisbane:\u00a0 -0.1\u00b0<\/li>\r\n<li>Adelaide:\u00a0 -0.5\u00b0<\/li>\r\n<li>Hobart:\u00a0 -2.8\u00b0<\/li>\r\n<li>Melbourne:\u00a0 -2.8\u00b0<\/li>\r\n<li>Perth: -3.4\u00b0<\/li>\r\n<li>Sydney:\u00a0 -8\u00b0<\/li>\r\n<li>Canberra: -10\u00b0<\/li>\r\n<\/ul>\r\n<p>Not as many capitals have gone over 45\u00b0 but I&#8217;m sure the list will grow over the 10 years a Sungrow battery warranty is supposed to last:<\/p>\r\n<ul>\r\n<li>Sydney:\u00a0 45.8\u00b0<\/li>\r\n<li>Melbourne:\u00a0 46.4\u00b0<\/li>\r\n<li>Perth:\u00a0 46.7<\/li>\r\n<li>Adelaide:\u00a0 47.6\u00b0<\/li>\r\n<\/ul>\r\n<p>In these days of global roasting, you could have a Sungrow battery installed in December anywhere in Australia and then be hit with a heatwave in January that will &#8212; technically &#8212; cause you to lose your 10-year warranty through no fault of your own.<\/p>\r\n<h2>Sungrow Is Likely To Fix This<\/h2>\r\n<p>I&#8217;m fairly certain Sungrow has no intention of pissing off customers in its largest overseas home battery market by declaring the weather has rendered their warranties void.\u00a0 So, the good news is that the temperature range given in the installation manual on their website was probably a mistake.\u00a0 After all, it contains other gems such as&#8230;<\/p>\r\n<blockquote>\r\n<p>&#8220;Remove batteries and other ignition sources from the scene of a fire.&#8221;<\/p>\r\n<\/blockquote>\r\n<p>Good luck with that.\u00a0 It weighs at least 114kg and has securely connected cables that lack slack.\u00a0 You could try to remove the modules separately, but unbolting them in an emergency won&#8217;t be fun.<\/p>\r\n<p>It doesn&#8217;t make sense for a company that worked to build a good reputation and generally follows Australian consumer law to intentionally screw over customers this way.\u00a0 But they do need to fix this.<\/p>\r\n<h2>Consumer Guarantees<\/h2>\r\n<p>In case you&#8217;re still a bit worried, you always have the fallback of <a href=\"https:\/\/www.accc.gov.au\/consumers\/buying-products-and-services\/consumer-rights-and-guarantees\">Australian Consumer Guarantees<\/a>.\u00a0 These protections apply regardless of what written warranties say and cannot be removed by companies.\u00a0 While I&#8217;m no lawyer, I am very confident they&#8217;d apply if the temperature where your battery was installed dipped below zero or exceeded 45\u00b0.\u00a0 If you sell a battery that can be installed outdoors in Australia, you can&#8217;t refuse to support it if it gets exposed to normal Australian temperatures.<\/p>\r\n<p>Also, under Australian Consumer Guarantees, you can claim for reasonable losses resulting from a faulty product.\u00a0 Having higher electricity bills, caused by not being able to use your battery, seems like a reasonable claim to me.\u00a0 But I wouldn&#8217;t bother to make a claim if an issue with my battery was resolved quickly. I&#8217;d cut them a bit of slack.<\/p>\r\n<h2>Making A Claim<\/h2>\r\n<p>If you have a problem with your battery, you should contact your installer first.\u00a0 They accepted your money in return for a working battery system.\u00a0 But if they&#8217;re no longer around, you can directly contact Sungrow to make a warranty claim.\u00a0 To do this, you&#8217;ll need to provide proof of purchase and, if it&#8217;s not connected to the internet, you&#8217;ll have to provide them with a copy of&#8230;<\/p>\r\n<blockquote>\r\n<p>&#8220;Battery log data including running information, error history and event record.&#8221;<\/p>\r\n<\/blockquote>\r\n<p>Since it&#8217;s always possible for something to go wrong if you are keeping these records yourself, I&#8217;ll once again recommend connecting it to the internet if it&#8217;s an option.<\/p>\r\n<h2>A Good Warranty &#8212; Apart From The Whole Temperature Thing<\/h2>\r\n<p>Compared to other home battery warranties, Sungrow&#8217;s is mostly good.\u00a0 While it only promises 60% retention of its original capacity, the number of kilowatt-hours of throughput allowed is relatively good, especially in its price range.\u00a0 The company also clearly cares about reputation and generally follows Australian Consumer Law.\u00a0 Sungrow is also the world&#8217;s second-largest producer of inverters and seems to be financially healthy.\u00a0 This means it&#8217;s very likely to still be around in the future to honour its warranties.\u00a0<\/p>\r\n<p>The fly in the ointment &#8212; or perhaps dendrite<sup class='endnote'><a href='https:\/\/www.solarquotes.com.au\/blog\/sungrow-battery-warranty\/#en-70736-1' id='enref-70736-1' onclick='return hhEndnotes_show(70736)'>1<\/a><\/sup> in the battery cell &#8212; is the ridiculous 0-45\u00b0 ambient temperature requirement in the installation manual that &#8212; technically &#8212; makes their warranty complete crap.\u00a0 But I&#8217;m sure this is a mistake that Sungrow will fix soon.\u00a0 Just how long this will take, I don&#8217;t know.\u00a0 These big companies can be slow to respond.<\/p>\r\n<p>All in all, given the battery is competitively priced, generally reliable, and that Sungrow usually follows Australian Consumer Law &#8212; I&#8217;d say it&#8217;s one of the better-value batteries available.<\/p>\r\n\n\n","protected":false},"excerpt":{"rendered":"<p>Could Bad Weather Kill Your Battery Warranty?
