Are the IQ-7 inverters going to remain available? The additional cost of
the IQ-8 micros killed one project where I couldn't find a good source
for IQ-7s.

That is correct, Jay. You only need the rapid shutdown switch if you
have IQ 8s and an IQ System Controller.
One of the big advantages of the IQ 8 over IQ 7 when paired with
storage is that the 1.5 PV to storage ratio does not apply, so you can
install larger PV systems with smaller battery systems.
Cordially,

Hi Jason
And if you don't have the smart controller/battery system then you do
not need this proprietary rapid shut down switch correct?

Yes, they require a proprietary rapid shutdown switch that connects to
the smart controller. This would be in addition to a visible load break
disconnect if the utility requires it. You cannot fulfill both
requirements with one switch, and it requires a line voltage circuit be
run from the smart controller to the rapid shutdown switch.

Do you need the additional switch if you use the Enphase battery?

Subject: [RE-wrenches] Enphase IQ7 versus IQ8
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.
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.
Am I missing something about the switching speed, energy harvest
capability, or the way they interact with batteries that makes them
better?
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.
