Bob,
I assume you are talking about feeders.
Although most people are against aluminum
wire it is really quite safe for feeders if installed properly.
To do this the lugs should all be retorqued after one year.
Aluminum "flows" under pressure, that is the steady pressure

How can this be approved? so a homeowner takes an extension cord and plugs in
solar after solar he has a 20 amp circuit and on one end he has a 20 amp
breaker and on the other he has 20 amps of solar, now he has an overload and no
protection, underwriters says no way on insurance!

Looks to me like Clarian just borrowed the HP Guerilla Solar concept and
somehow managed to get it approved.

Some of the combiner boxes MUST be mounted vertically, other can take up to
a 15 degree tilt, and if my memory serves me correctly (which is a 50-50
proposition) there is one box that can lie horizontal. It should already
have a DIN rail and could accommodate a bunch of touch-safe fuse holders. On

Soladeck does not specify their 600 volt, 120 amp listing is ac, dc, or
dual. And yes, an AC rated Outback combiner would be nice.

One 45 kw, so roughly 15 ac branch circuits, one 26 kw, roughly 10 branch
circuits, roof roughly 20 degree slope on both.

Marco,
If I understand your question, not sure I do, my answer is, there is no
requirement for such a relationship.
Repeat to yourself, what Darryl said:
Always check rotation either with a rotation meter or with a motor by bumping
the motor to check its rotation.

Hi Kirk,
First, a couple of questions:
1) what is "larger Enphase systems" (number of load centers) and
2) what roof angle?
Now, if you buy into the hype that, with Enphase, shading is a minor detail,
you may want to consider using something like one or more cupola(s) to mount
the stand
Soladeck can hold 5-6 branches with some added din rail parts.
I have used ac din rail breakers in those Outback and MidNite combiners.
Likely legit and it was wall mounted.
Thank you,
Maverick

Hello,
I am about to start some larger Enphase systems, and I'm wondering if there
is an AC combiner out there (outdoor load center, etc) that is listed to be
mounted at an angle(meaning roof angle), ala the Outback DC combiner boxes.
I want several combiner / discos on the roof and it won't l
