<p class="MsoNormal"><o:p> </o:p></p>
<div>
<p class="MsoNormal">I am trying to figure out why it is a good idea we use the IQ8 in anything other than a solar only backup scenario. If there are Enphase batteries involved, wouldn't the IQ7 do the same job on the roof? In a straight grid tied scenario,
again the IQ7 would do the exact same thing. You would not have an upgrade path to solar only backup, of course.<o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I'm just having a hard time understanding the value proposition of the IQ8 in most of the situations I encounter. They cost significantly more, and you need an additional rapid shutdown switch when using batteries that can be quite a pain
in some scenarios.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Am I missing something about the switching speed, energy harvest capability, or the way they interact with batteries that makes them better?<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">P.S. I am aware of the very small power output differences by model number and I am referring exclusively to 240 volt applications. I understand the 208 volt advantages of the IQ8. <o:p></o:p></p>
