If you look at the graphics on the website, they're really showing
temporary mounted PV. This is not designed to be hardwired for an NEC
approved installation. It's like a portable generator. I'd get the guy
a couple of modules on folding racks, and make up a 50 ft portable cable
so he can set the modules in the sun to charge if its a long outage.
I've done a few of these for folks, using like the little Jackery
systems. Ryobi, Milwaukee, etc make "battery generators"; same
concept: you're not going to hardwire them in to anything. Its got to
be portable to stay compliant.
If he wants the PV mounted to the roof, you're either throwing code out
the door, or he needs a different inverter setup.
