Sammy,
If they were Platinum Diehard Marine batteries built by the Legendary Odyssey people -
a month without a charge would mean Little if they were full and had no drain on them when
you took off. Hidden away (nice and cool) I might add.
Guess I've seen just a tad too much rip-off and the dark side in my time.
The first thing that goes through my head is how long does this stuff hang around when
your gone. You talk about disco-ing the turbine when you leave. Can you take it with you
or is that not realistic?
A fellow I know is setting up a remote vacation (and some weekends) cabin.
He asked me for my 2 cents worth and I suggested a cheaper 'dummy' battery bank with
some 318 pound Rolls 5000 Series batteries (mamma's) buried nice, neat and clean
for the real show.
Solar enough to keep everything up with some trick wire (that we are working on) going to
the hidden battery bank. If that doesn't pan out he may have another option to keep his
generous sized storage batteries up when gone.
The cool, buried temperature should help a lot. Getting a maximum amount of Ah discharge out
of the hidden bank is not necessary.
It seems that a somewhat over-sized bank can have a number of advantages.
This guy doesn't plan on playing that sorry run them 85% dead song on his juke box.
He plans on taking in a fuel efficient, quiet compared to most, Yamaha Generator with him.
2,000 Watts should meet his needs. If he was there all the time it would be different.
When it comes to 12 Volt systems I follow the RV crowd which I also play at. When it comes
to 24 Volt systems it's time to run after the Yacht crowd. Those boys have some real nice toys
including 24 Volt Universal Battery Chargers that seem to be a good 10% more efficient than
any 48 Volt deal that I can find. Soon I have to run after the Golf crowd to see what their
latest 48 Volt goodies are doing. Last time I looked they talked a good game but
the efficiency figures were too hard to locate.
It's a technique that seems to work in a number of situations.
Jump into a high dollar hobby to see what they have. At least mentally.
