It's a tough design question for sure without data. I don't like these
situations. In my opinion you really need to overshoot, especially on the
battery capacity if it will be hard to add later. Obviously that gets
expensive.

I considered a 96-cell panel, but the highest watt panels don't compare to
new 72-cell panels coming out in the 400+ watt range. It's a good fallback
position because I might be losing more in the conversion than I am gaining

a non-issue in my local area, but it may
vary in other locations where clipping is more common. The heat here
results in little clipping at a 132% ratio here, and I guess at 145% the
morning and afternoon advantages largely outweigh the mid-day clipping
increase.

I would never accept this from my distributor. It would be going back with
a full refund or I'd take my business elsewhere. My distributor would never
accept this from a manufacturer I would think. That's the whole benefit of
having a middleman - they are paid to deal with these kinds of issue!
it a practice to only allow service rated enclosures for

I would add that S-5s are only as good as the roof. We saw a large system
(not ours) that ripped the metal right off the roof during Hurricane Irma.
It literally tore the meta. The panels, rails, and S-5s were still
connected, sitting on the ground with chunks of metal roofing still
attached to
There is a glaring lack of good options for 5V metal roofs in Florida.
Sure, there are some butyl tape based attachments that penetrate the metal,
but what happens when the truss lands below a V-crimp? The only real option
is a deck mount solution or truss blocking (which is excruciating in a
True, but this is MUCH less of a problem with IQ compared to M-Series.
I just installed 212 IQ micros on a building with 268 existing M-Series.
The M-series required ferrite rings and the IQ worked flawlessly without
any filtering (although it took about 3 hours for all of the IQ micros to
tallation). I agree with Enphase on this point - get it connected
to broadband, at least temporarily to diagnose issues. I have gone as far
as using an Ethernet wi-fi bridge connected to my mobile hotspot to
diagnose issues.

pricing that would be perfect for flat labels and placards. Regardless,
they have always been very reliable for us.
