Yes. The inverter is sent off for certification without the cord to plug it in. Then when the "kit" is put together the cord is added. The sytem as a whole does not pass UL listing or NEC code when installed but the inverter by itself will pass. Still doesn't make it safe. Just playing with packaging.
Many idiots will hook these up and find out they have meters that don't record backwards. They end up paying the PoCo for any power they may send back to the grid.
At this time there is, AFAIK, only one NEC compliant, UL listed, plug and play GTI. And it is possible only because they stretch the definition of PandP.
It requires that you have a licensed electrician install a special non-standard socket, following all of the PV rules as if the socket were a hard wired GTI. Then you take the cord from their inverter which has a matching non-standard plug and connect it.
The only thing their system does is keep the electrician from having to wire into the GTI chassis itself. In any jurisdiction that has taken a close look at it, the installation of the special socket requires a permit and inspection just like any hard wired PV.
If I remember correctly it uses microinverters or AC panels to avoid needing an inspection of the DC wiring.

I have been on that guys website (M Engineering) and I believe you are correct it is the only "plug and play" solar kit out there. It is still expensive at $3.50/watt without any installation.
