We installed some D380s a few weeks ago, and it was obvious (as soon as we looked at the price list) that the reduced cost of the inverters was eaten up by the additional cost of the cables. However, Enphase has been developing another cable system, which should replace the existing D-380 cabling system by next year. Magnus has been working on the next cable system, and brought out a prototype to one of our projects during the layout phase. That next cable system will be more versatile, but will not cost much less.

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.

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.
