Solaredge HD-wave

[sensij]

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.

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.

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

...it does not appear that the marvelous HD advanced technology is anything more than use of pulse width modulation an a high switching frequency...

It's a bit more than that. They are using multi-level modulation: in simple terms, they are varying both the height (voltage) and the width (duration) of the pulses. That has been done before on higher power inverters but not I believe on residential units.

well don't expect them to tell you. Everything in solar seems to be very confidential.

If its really that good, their competition will reverse engineer it. I'll be watching; have done such
things myself. I was already pretty impressed with most aspects of current inverters. Bruce Roe

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 Roe

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.
