Are you a fan of the modular architecture?<\/em><\/p>\n<p><strong>Don:<\/strong> <em>We&#8217;re massive fans of modular architecture. It gives our customers the absolute freedom to add extra modules as they require.<\/em><\/p>\n<p><strong>Finn:<\/strong> <em>What&#8217;s your best guess? How long is it going to take today?<\/em><\/p>\n<p><strong>Don:<\/strong> Adding one module will probably take us about an hour today<em>.<\/em><\/p>\n<p><strong>Finn:<\/strong> <em>So I&#8217;m adding one module today, 3.2 kilowatt-hours.<\/em><\/p>\n<p><strong>Don:<\/strong> <em>Sure.<\/em><\/p>\n<p><strong>Finn:<\/strong> <em>But if I wanted to add, say, three modules, how long would that take?<\/em><\/p>\n<p><strong>Don:<\/strong> <em>Yeah, adding one module or three modules is pretty much the same amount of time. It&#8217;s literally taking the head unit off, dropping the new modules in, and then replacing the head unit and commissioning. So you&#8217;re probably talking an extra 30 seconds per module. On this particular model, you can go up to 25 kilowatt-hours worth of storage, which is eight modules.<\/em><\/p>\n<p><strong>Finn:<\/strong> <em>Yeah. Cool. And that&#8217;s going to be more than enough for most homes?<\/em><\/p>\n<p><strong>Don:<\/strong> <em>Definitely. Most homes, the average home we see around that 16 kilowatt-hours worth of storage generally does it.<\/em><\/p>\n<p><strong>Finn:<\/strong> <em>If this wasn&#8217;t modular and I wanted to add a second battery, how long would that take an electrician?<\/em><\/p>\n<p><strong>Don:<\/strong> <em>To add a second battery, you&#8217;re probably talking six to eight hours worth of work to put in a full battery with cabling and wiring. Going modular from the beginning allows you to have everything in situ and ready to go, and then it&#8217;s simply dropping extra batteries on top of the stack to get that desired kilowatt-hour storage that you&#8217;re looking for.<\/em><\/p>\n<p><strong>Finn:<\/strong> <em>Cool. Well, let&#8217;s see if you&#8217;re right and if you can get this module on in under an hour.<\/em><\/p>\n<p><strong>Don:<\/strong> <em>I&#8217;m sure we will.<\/em><\/p>\n<h2>Race Against The Clock<\/h2>\n<p>Don predicted adding the module to my stack would take about an hour.
