[Elecraft] Solar Charging Controller

Ok.. you have a square wave doing the charging.  This puppy is going to be VERY noisy electrically.  Probably good for lead-acid flavored batteries, but not for the new lighter varieties.

Hi All,

I like to "haunt" the bargain and close-out websites.  This item showed up 
on Rakuten's website (formerly Buy.com).  A 30 amp solar charger for about 
$20.00!  Here's a link:

http://patazon.shop.rakuten.com/p/patazon-30a-solar-panel-power-battery-charge-controller-regulator-12v/264381220.html?scid=em_Promotional_20140909DAILY&adid=17653

I'm not familiar with the product, but it seems to be something that could 
be useful for those of us who like/want to do solar panel charging from time 
to time.

I have a couple of different sets of solar panels--one set I keep in my 
motorhome, and the other is at home.  Since I only have one controller, this 
might be a good opportunity to eliminate the need for carrying the one 
controller back and forth.  I'm curious, though, if anyone else has ever 
seen/used this particular controller, or one from the same manufacturer.

More and more I hear about others who have gone to solar charging, and I 
have lots of opportunities to do the same.  Dry camping is something I do a 
good bit of, and keeping the rigs running on battery power usually means 
needing a generator along.  If I'm running QRP it isn't a big deal, but if I 
want to run a bit higher power, then battery consumption gets to be an 
issue.

Anyway, I thought I'd pass this on in case anyone else might find it to be 
of interest.
