I am going to install a solar panel with charge controller but with 2
battery banks, it seems I have to use a duo controller so I feed each
bank separately. If I hook a single controller downstream of the
selector switch, the switch would have to always be in the both
position, which is not desirable.
What say you all?
The price difference between a single and a duo is $45 vs $169.

Two singles for complete redundency and isolation.

But you had already figured that out, right?

After a ton of research, I've come to the conclusion that solar on a
sailboat is nearly worthless unless you can mount huge arrays pointing
all different directions with multiple controllers.
That said, the new tech stuff coming down the road may prove somewhat
effective.

There are many who would probably disagree with your conclusion. It
probably depends more upon what you need power for, and how you use
your boat. Solar panels are generally just part of the charging
system, not a complete solution by itself. It sure can reduce engine
run time, though!

What kind of boat do you have? Do you live aboard? Only sail on
weekends? Cruise for extended periods? Do you have refrigeration or
other big energy needs?

To that end, in benefit of the cruising community when, not if, they
find it, I'd like to put in a plug for you all to join the world network
of massive computer processing sorting through massive molecules for the
answer to a better solar array for everyone:

http://news.cnet.com/8301-11128_3-10114306-54.html

Go to he
http://www.worldcommunitygrid.org/
click DOWNLOAD NOW and it installs itself on Windows machines. Then,
just leave it run 24/7 using CPU cycles you have no use for with a very
brief data download/upload to the IBM/Harvard mainframe every 12-14
hours to report the last job and get the next one. I've been running it
5 days and it doesn't even cause my TV streaming to balk. It DOES use a
LOT of CPU computing resources, but you have lots more of them than
you'll ever need while waiting for the internet, ZZZZZZ and disk drives
ZZZzzzzZZZzzzzZZZ to access.

There's some kind of prize or braggin' rights, but I don't care about
that. What I'd like is an open source solar cell array to replace South
Carolina Electric and Gouge's meter, some day....(c;]

give it a go....your cost is almost zero.

great you get to load your own spyware. notheing like stupidity to get
you new huristics.

EXACTLY which spyware are you referring to? Nothing has been installed
onto my system except the heavy-loading computational system. It uses
21.4MB of hard drive space for data storage but empties it when it goes
into the report cycle. Looking at the file, there's nothing about me in
it at all and it's not encrypted, unless you consider physics and
chemistry cryptography in your world.

I'm running it wide open on a couple of dual core Intel machines and
there's plenty of CPU left to watch Livestation streaming, type this
nonsense to you and download more movies from alt.binaries.movies.divx
to play on my Nokia Linux tablets.

It also doesn't upset my movie viewing on the same machines. It only
uses internet bandwidth about once ever 28 hours of number crunching to
get the next job from the server and to upload the report of the last
job, about 30 seconds, tops. The current job has been running full bore
for 26 hours and has about an hour and a half left before it uploads its
findings and starts the job it got this afternoon.

If you know of any spyware, I'd be happy to investigate it.....

GOOD GRIEF! "Love Cypress" commercial just came across Euronews and
after seeing the thong-clad model walking through the Mediterranean
white sand beach, I'M READY TO GO!.....How DOES she keep from falling
over on her face?? It defies Physics!

Just went and had a look at the site you quoted.
Looks interesting - I think I've heard of it but not in that detail.
Joined up also and downloaded the stuff.

You'll actually find out that this is based upon the BOINC platform,
which supports many different distributed computing projects. It
actually grew out of the SETI (Search for ExtraTerrestrial Intelligence)
project which was started in the mid-90s, which was when I started using
it.

You can find info on BOINC at http://boinc.berkeley.edu/

There are currently 319,060 active contributors running this on 567,770
computers producing 1,441 Terraflops per hour! I personally have
contributed almost 27,000 hours of computing time, which places me at
the 96% percentile of BOINC contributors and 94% in the US.

http://boincstats.com/stats/boinc_us...de39e8f890005a
30e5de9dfd848a929


Just note that running this does cause your computer to use a lot more
power. On board my laptop draws ~2A @12V when just running, but draws
close to 8A when running BOINC.

When children hear a new word they love to use it, even if they don't know
what it means. Perhaps Gordon never lost that urge.

Huh?
