Despite making solid gear with a very flexible panel level optimiser option, their position in the market became politically untenable, and they withdrew from Australia.<\/p>\n<p>There are around 40,000 Huawei hybrid inverter systems installed across Australia.

It grew from a humble one man plumbing business into one of the country\u2019s largest integrated solar and solar hot water installers. With 23 offices and more than 190 staff across Australia, the empire includes SG Wholesale as a trade supplier with 8 branches across WA, SA, Vic ACT &amp; NSW.<\/p>\n<p>While iStore is a related company to Solargain, the two operate as separate businesses with iStore being a wholesale supplier, supporting retailers, installers and end customers nationwide.<\/p>\n<div id=\"attachment_98071\" style=\"width: 684px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" aria-describedby=\"caption-attachment-98071\" class=\"wp-image-98071 size-full\" src=\"https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2026\/03\/finns-bike-istore.jpg\" alt=\"iStore solar battery\" width=\"674\" height=\"793\" srcset=\"https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2026\/03\/finns-bike-istore.jpg 674w, https:\/\/www.solarquotes.com.au\/blog\/wp-content\/uploads\/2026\/03\/finns-bike-istore-255x300.jpg 255w\" sizes=\"(max-width: 674px) 100vw, 674px\" \/><p id=\"caption-attachment-98071\" class=\"wp-caption-text\">Two stacks of iStore equates to 30kWh, installed very neatly by Solargain Adelaide.<\/p><\/div>\n<h2>Batteries Are Changing<\/h2>\n<p>Like many other companies, iStore are increasing the size of their batteries. 5kWh units will soon grow to 7kWh. So if you are considering a new battery for your existing inverter, it could be a good time to get moving.<\/p>\n<p><strong>However if you already have an iStore or Huawei system that uses 5kWh battery modules, and you\u2019d like to expand, it\u2019s critical that you act now.<\/strong><\/p>\n<p><em>New model batteries are not compatible with old ones.<\/em><\/p>\n<p>So unlike a GoodWe for instance, you can\u2019t mix and match module capacity in the same stack.<\/p>\n<p>As I understand it though, a whole new stack of batteries complete with base and head unit, can be connected in parallel with a legacy stack. That&#8217;s a lot better situation than many others, like for example alphaESS, where every new model offers zero backward compatibility.<\/p>\n<p>We&#8217;ll write more about the improved range of <a href=\"https:\/\/www.solarquotes.com.au\/battery-storage\/reviews\/istore-review.html\">iStore batteries<\/a> as the information comes to hand. There&#8217;s some word they&#8217;ll offer stacks of 4 (up from 3) but for now there&#8217;s nothing revolutionary enough I&#8217;d say it&#8217;s worth waiting for.<\/p>\n<h2>Privacy Law Leaves Huawei Customers Isolated<\/h2>\n<p>It\u2019s sometimes said that a true patriot is the person who gets a parking ticket and rejoices that the system works.
