<div dir="auto"><div>Hi Al,</div><div dir="auto">A working micro that is mounted directly to the back of the module (i.e. AC module) will be warm and you can see that in an IR scan. But for the module as a whole, if the micro is working, then the sun's energy turns into electricity rather than heat. This actually makes the module cooler than if the micro was not working.<br><br>Cheers,</div><div dir="auto">Dave<br><br><div class="gmail_quote" dir="auto"><div dir="ltr" class="gmail_attr">On Fri, Jul 31, 2020, 7:13 AM Al Frishman <<a href="mailto:evolvedsolar@gmail.com">evolvedsolar@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="word-wrap:break-word;line-break:after-white-space">Hey Dave,<div>I am curious.
