there's no big conspiracy going on here that everybody is just keeping quiet about. there simply are safety issues the average person does not understand or know. a plug? so should i guess who you would have installing that? heck you haven't even considered that the item itself could be unsafe as it is untested or certified. i am not a big person here on the nec and many here will tell you that, but the average person will do one of the following,
1> operate ok be it accidentally or with knowledge
2> blow out the inverter(s) and/or circuits and items they are attached to
3> get shocked, possibly hurt or killed
4> catch the unit(s) and/or circuit wiring on fire
5> keep popping breakers
6> some combination of these
these are not appliances to plug into a wall. if you really want to do it and want to semi skip some of the hassles of gt then go off grid with batteries and run a appliance directly and that may need to be a prechecked kit to semi see to it that this is being done ok. any deviation from that may be hazardous too for those of the typical public. to be honest with you, even for off grid i have recommended learning before you do anything and have not advocated kits because you don't know what you need or what options you have. electrical generation isn't simple, easy, and safe when done by inexperienced and unknowledgeable people. those on this forum are in favor of solar, but we all had to learn some of the ins and outs to do it right. if you don't want to learn then you shouldn't do it. at least with this stuff you can do the work yourself in your home without a license if it's inspected, but never with unapproved equipment.

I disagree with your assumption that the Gateway is "wired between the breaker box and the circuit in question". If you look closely you will see that the Gateway is simply plugged into another outlet on that same branch circuit.
I think the Gateway is for the internet connection for Online Montoring & Power Tracking of the modules.
EDIT: (I was wrong. The Gateway can do more than just internet access. I found this info below after posting ...)
"... A third piece of equipment is a circuit monitor, which looks something like a thermostat, that ensures electricity flows into the home wiring without overloading any circuits, explained Maglaque ..."
The Inverter Modules do support Anti-Islanding.
There appears to be an Enphase type inverter mounted on the back of each Solar Panel.
There is a limit of 1,000 watts total power generation per 15A circuit.
How does their system enforce that?
I hope they do get UL approval for this concept.

Yes, I see now that the Gateway seems to be plugged in. The question then remains, how does it monitor total circuit amperage?? I see no way of doing it by only using plug-in modules.
How about creating a common "plug n receptacle" that is unique to renewable energy plug n play systems - for example like the J1772 for electric vehicles? So, for instance you have solar or wind with integrated inverters, that produces A/C power, goes from source to "new plug and receptacle" that has a dedicated branch to the breaker panel. Rather than having a lengthy review process for permitting - everything is pre-approved by way of manufacturer, so the inspector simply comes out and makes sure that the circuit is a dedicated circuit and the plug in properly connected...
Hmmmm... am i just babbling? I feel like there is a solution, it just has to be sussed out.

The inverter(s) could send amperage information over the power line or wireless to the gateway. To limit power on the AC lines, bet the gateway limits total power for the entire house to 1000 watts. This way, whether the inverter(s) are on a single line or different lines. It will be within NEC safe limits.

There are ways it could be done with "smart outlets" or "smart breakers" plus "smart GT" inverters... Even retrofit a current transformer on a branch circuit plus a smart GT inverter could all work together safely and probably even to code...
