Is this the future? They say it available in December of this year.

At first glance and listening to the description, it does not appear that the marvelous HD advanced technology is anything more than use of pulse width modulation an a high switching frequency to avoid the need for a large amount of iron and copper in either inductors or transformers.
The on/off switching may be using better semiconductor technology than the older MOSFET designs, allowing lower switching losses and therefore higher efficiency.SunnyBoy 3000 US, 18 BP Solar 175B panels. -
I don't see anything revolutionary in the operational description. Sure it can be made smaller
by raising the switching frequency. But the catch to that, is usually lower efficiency. These
guys claim over 99% efficiency; if they really can do that, I want to know how. Bruce RoeComment

It'll be interesting to get the details on this. As usual, the website video is pure marketing fluff.Comment

When I first saw the company promo vid a couple months ago I was thinking I wished I had it, faster, better, sleeker, etc and I'm ready to trade in my 5 month old SE5000. Not really, but its interesting how the promo compares it to their own, current SExxxx model as if it will be obsolete. For anyone considering it, I'd think there's an element of risk similar to what the Enphase M190's are going through especially since I'm sure Enphase did extensive testing on their first version. Comparing to this "HD" version not for the same reasons, but at least the SExxxx series have been out a few short years. I mean it's still electrons in and out, right, difference is just size and maybe 1% improvement? All said, I think I'd wait a couple years into production and see if they come out with a convertible version, with leather interior.Comment

I pretty much agree with this. From what I understand, the HD-Wave version is trading out more tested / established inverter circuitry for an architecture that has more points of failure using components that may be more prone to failure. From my perspective, lots of risk for not much gain.CS6P-260P/SE3000 - http://tiny.cc/ed5ozxComment

The thing SolarEdge could get out of this is lower cost due to the smaller overall size (less metal, plastic). In terms of whether it'll be more or less reliable, it depends upon the design. I led product design (and production) teams for 25 years, so know that some organizations put timeliness ahead of quality. That always costs a company more in the long run. The place I worked longest for had a mantra: safety, quality, timeliness, cost (in that order) and we engineers were evaluated to that. Point is, we don't know the SolarEdge internal processes, so it's hard to know whether the "HD wave" will be more or less reliable. At least the financials of the company look good enough that they may be around long enough to make good on their warranty.Comment

this is a great topic and I wanted to revive it

will the bigger units like the 7Kw have the power outlet option as advertised?
SELF-SUSTAINING POWER OUTLET (OPTIONAL)
Nominal Output Voltage 120 V
Maximum Output Power 1500(2) W
External Outlet with GFDI YESComment

yeah the efficiency is nice but they are smaller lighter so easier to install and fit into places.
The also meet rapid shutdown for 2017 code. (automatic shutdown)
The energy coming out should be a smoother curve as well.OutBack FP1 w/ CS6P-250P http://bit.ly/1Sg5VNHComment
