I was wondering if anyone had bought one of these, their experiences,
caveats, pros, cons, likes, dislikes, etc.

Judging from what I can see on YOU TUBE, the quality varies all over
the spectrum, as does the reliability.

I'm sure the fellows here would be interested in hearing your
experiences and if you could recommend a reliable unit and vendor?

Well they sold medicine in South America which killed many people and when
someone was interviewed about this, they said it was good for the people of
China because they were making money!

I don't associate the words "Made in China" with quality, nor good product
instructions/documentation, nor product support, nor software which works
properly.

I suggest before buying, you go to the manufacturer's web site and try
downloading documentation and software updates. See if you can request
warranty service or can report a problem with the product. I would imagine
you will not get far...

Geee. Maybe because the websites are in Cantonese?

Everybody that isn't USanian isn't an idiot because they produce to the spec
given them.

Yes, they do work and it's a way to get started wtihout spending
$,000, some of the 250 watt units are under $00.  From the many
I've seen on You Tube installations, there are some with somewhat
sloppy battery terminals, not the best quality.  Some seem to be
very well made and if you watch the tests done by the users,
they work just fine.  Some have been in use for a year or so, and
some have failed in a month or two, but they are replaced for free
in one case.

I would like to see a graph of power output vs input voltage.

Most are rated at minimum of 14 VDC input, but a few are advertised
as working down to 10.4VDC.  If that is the case, it would work on
a 12v battery system, but how much power out do you get at that
low voltage?  Inquiring minds want to know.

One fellow on You Tube had at least 5 or more running off his panels
with
no problems, and he switched them in and out depending on the
sunlight at the time.

As far as Chinese quality, this IBM laptop (now Lenovo) has not missed
a beat and has been with me around the world many times under rugged
conditions.  Cellphones are made in China, as are many other high tech
items.  Not like it used to be.

I'm hoping HOMEPOWER magazine will do a report on them and which are
the best to buy, but unfortunately they don't advertise in
Homepower....
