Questions about The One

[ralph day]

As much as I love Midnite products (Clipper, 2 x Classic 250's), I was in the market for an inverter in 2015, but their first offering was about 4 iyears later. 

Either you wait patiently, or go with another product until MS comes out with their promised things (and they always do)

Fair point, although I'm talking about a software feature added to an existing product.  Hardware development is a lot slower and more complicated than adding software features, especially a new interface like described here.  Four years for a hardware product like the AIO is a reasonable timeline... maybe even pretty quick.  I've delivered software features like this in weeks or months, from start to finish, including QA/testing/documentation.  A big factor will be how much computing hardware they've got available in their box, of course... but these days it's surprising to not have enough.  Five years ago when they would have been starting component selection, a typical single board computer had 1-4GB RAM and 1-6 cores running at 1-2.5GHz.  For such a board to support running a simple webserver is trivial, and plenty of open source solutions exist to do most of the hard work. All they really need to add is the details of the higher level interface they wish to create, and the modbus code they must already have.

All just informed speculation, of course, it's entirely up to Midnite.  My guess is that their bottleneck is the manpower to implement such a thing, and whether it is a priority for them.  I really hope they see the potential in the idea as it would set them apart from the competition, and I'd guess that their competition would then have to scramble to catch up.  Being first mover means they don't have to scramble to be the one catching up!

Is there more detailed data about The One's surge capability available?  The quoted 20,000VA & 13,000VA per leg is for 1 second.  Presumably there is a ramp from the rated 10kW continuous (i.e. lifetime seconds) down to 20kVA for 1 second.  Is there a plot available, or at least another data point or two?  I'm contemplating my backup panel loads, and the smart load capability I'm considering and how quickly I would need to detect an overload.  I have an energy monitor that samples every 5 seconds, so it would be interesting (for example) to know how big a surge The One could handle for 8-10 seconds.

Also, why is the surge capability quoted as VA and not watts (which is volts*amps)?  There must be some subtlety behind that choice?

Does Midnite monitor its own forum for questions like these?

Intimately.

In the 0 post of this thre4ad ASword asks: "How loud can The One get during operation?"
And FNG responds in post 1: "10- The inverter is almost silent the fans however will be heard as with any fans when it is running hard."
The spec sheet for the MN15-12KW-AIO does state <40 dB for no load noise level. Very good and in agreement with FNG.

Can we also get a numerical value of sound level for "full load" and for perhaps some more typical operating level, perhaps 30% of full load?

Thanks in advance.

Thanks, ASword Good video.
