I think this review has been posted here before. The PhD rebuilt major sections of the PowerJack to make it work reasonably well and safely:

Can someone please point me to one online news article of one of these inverters that has caused a fire?

I think you should buy 6 of them and plug,them all into a single 15 amp household circuit and see what happened when some one plugs a 1500 watt hair dryer and a 1500 watt space heater into the same circuit. Guess what the breaker won trip.
BTW tells us how long before the fire breaks out.

Which is why the revised instructions specify that you plug them into an isolated circuit with no loads on it. That way the breaker for that circuit protects the wiring from overload. Of course if one of them partially shorts out, the other 5 will happily drive up to their full output into what is left of it, protected only by the internal breakers of all of the other GT inverters. Unless enough power is pulled from the grid to trip that breaker, in which case the anti-islanding circuits should shut them all down. Maybe....

I have been doing some research on these types of instalations and have not come to any type of conclusions as to its legality. there are many sites explaining how to get this type of install setup and as far as if its legal... well I have seen many installs of this type of nature (however not plugged into a wall outlet but direct to the box) was cleared thru permits and even the utility company in the USA. as shown here http://www.youtube.com/watch?v=uWRrjlDlPJs&feature=related using 2 powerjack inverters I am asuming the inverters are about 1000watts ech. since he said he can put out about 1.6khz on a good day

I am going to throw this out there and may get wacked for it but my thoughts on this type of setup however if I were to do it I would wire directly to the util box not a house plug.
I believe these are the people that are solar installers, people that have spent thousands on installs, or people that dont believe its a good idea to do it. these setups are NOT recommended by some solar companies, mainly because they want people to think they need a installer to do it. however you do have to get a electric permit my area charges about $125 for the permit. you do not need a building permit unless your mounting the panels on the roof.
nor do they need to be connected to a GFI plug if your panels are not on the roof.
Westinghouse and CBD on June 5 announced they are to begin distributing Westinghouse’s DIY “plug n’ play” solar power systems, dubbed Instant Connect, in Australia.
Also the DOE Dept of Energy is researching plug and play setups ie Solar panel >>> Inverter >> Wall plug. so how illeagal can it be?
As long as your using a grid tie inverter that can detect when the grid goes off line.

I am new to the solar thing (as you will be able to tell by my questions). I have been watching YouTube and the videos of everyone's very basic beginner systems. Most are using low cost (cheap) 250w to 400w grid tie inverters. Most say they have "island protection" but are not UL listed.
So my question is: are these people putting power back to the grid and the power company really doesn't know it? Meaning they are producing much less then they consume? I guess you can say they are doing this illegally?
My second question: If the manufacture says it has island protection...which seems to be the main safety issue for the PUD. Does that mean it doesn't work? I realize the whole UL listing comes down to cost most of the time, the cost of getting the listing. But what about actual performance...has anyone seen these say they have island protection yet it doesn’t work?
Just wondering what other people are doing....doing to get started without dropping thousands of $'s on systems???

Yes, and Enphase inverters are not things you find on eBay for an impossibly cheap price.
