Matt,
It does not provide backup, but it does provide power from the PVs (without a battery bank) which I don't see often. It's great to see more and more grid tie systems with backup. Most of the existing systems I have seen do not have it.

You're right. I totally forgot to comment on the unique feature. I agree it's interesting and I love to see innovation. I'm curious as to how they've designed this thing.
Unfortunately I don't think it will be of much use to most of my customers. Generally people's top priorities during an outage tend to be water and refrigeration. A submersible pump usually won't run on 1,500 watts without even considering the starting surge. I'm not sure if a residential refrigerator starting from a mid-cycle stop would start on that much power or not. I've have my doubts but no way to test it. Even then, keeping refrigeration going requires power when the sun isn't shinning.
For the uses mentioned, charging phones and what not, it would be pretty slick. Just not a substitute for a true back-up power system.
