22. Control method PWM pulse-duration modulation charge mode
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.

Subject: [Elecraft] Solar Charging Controller
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_20140909DAILYadid=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.
