[RE-wrenches] enphase D380

[Jason Szumlanski]

One advantage I see in larger systems is more inverters per string.
We're looking at doing a 208V ground mount job with panels arranged
24Wx6H. The D380 will allow just 6 strings with junction boxes all
neatly aligned. At least on ground mounts, wire management will be a bit
easier. I agree that the trunk cable makes the system savings less
attractive. The cables for the M190 are already no bargain.

 

Thanks for the good feedback.

Hi Benn,

 

No one else has tried the D380's?

We just commissioned our first D380 system, and I can't say we're too
impressed. Mainly, half of the cost savings from the doubles was eaten
up by having to buy the trunk cables, and at least all the labor saved
by mounting less inverters was eaten up by having to manage the bulky
trunk cables. The less-than-optimal reality of array wire management is
made more challenging by dealing with these big bulky things.

I think we would use these if Enphase goes back to the daisy chain
method of the single inverters, but until then, we'll probably stick
with the singles.

wrenches,

so i'm lining up a few installations using the newer Enphase D380
TwinPack microinverter and i'm just looking for any feedback or
"heads-up's" before getting started.  i'm not foreseeing any issues, it
is looking fairly straight forward like the M190's but nonetheless, if
any of you have any comments, they would be appreciated.  i'll provide
some feedback of my own once i've done one or two of these systems.  
cheers,
