I've seen this type of product before (PV integrated GTI) and from what I've read,
they have never been very successful.

I think one of the reasons is fear of not being able to replace the GTI, which might
fail, many years before the PV gets old..

Because, the GTI might be too embedded into the PV panel hardware, and because
the product is from a new company that might not be here to provide a new GTI
10 or 15 years down the road..

Enphase has spent a lot of money on product reliability testing.
They are out to prove their GTI units are going to last for a LONG time.

Plus, at this point in time, Enphase product failure records have started to build up.

Here's some info about problems with the new D380 inverters.

D380's failing at a high rate

It seems like Enphase really supports their products, when there is a problem.
I hear those M190s have a pretty good track record nowadays..
