Mac,
I pulled some notes from a thread on the StarOS forums, you might
want to go read the whole thing if this sounds interesting:
===============================================================
(gleaned from "Solar Power" thread on StarOS forum started 6/18/2006

Should power at least 8 WAR2.
Iota DLS-15 12v 15A battery charger (larger available) $116
http://store.solar-electric.com/ioen12vo15am.html
optional Iota IQ4 plugin smart charger $29 (not so important since
there will be a continuous load on the battery)
PowerStream 12v to 24v converter PST-DU700-24 $140 retail price
http://www.powerstream.com/
==============================
I was just thinking about powering a few radios, still trying to
decide between a 24V battery or 12V plus the extra converter.
The Iota plugs into AC and keeps the battery charged.
Oh, could you post some pictures of your tower on top of the grain
elevator sometime? Especially the base of the tower, just curious on
the specifics. (do the guys go all the way to the ground?)

PS - I thought we grew a lot of corn in Michigan, but I see that Iowa
does 8X as much. I think we have 15 ethanol plants built or in the
permit process, I hear those will consume the entire state's corn crop.

I have an 80' Rohn 25G tower on top of a 110' concrete grain

elevators power is giving me fits as they are flipping breakers on
and off
as they are in full swing with all the corn coming in right now out
of the
fields. I do have everything on UPS's, but need to move up the
ranks for
longer run times to 4 larger marine batteries to accomplish longer
run times
when the breakers are flipped off.
Here is my question: Do they make a device that has multiple DC
power output
voltages (12/18/24/48) that connects directly to a set of batteries
with the
ability to connect multiple devices and if so - how do you keep your
batteries charged? I would like to run my gear directly off the DC
power
instead of plugging everything into 120vdc and then have the wall
warts
convert to the DC power. I currently have 10 radios on top of the
elevator
and it is a major distribution point for the North and East legs of
our
network.
Any and all suggestions are welcomed!!
