I hope some folks in this group have the expertise to help me on this
I am an RV'er that likes to dry camp, and I carry (4) 115AH 12VDC
batteries. I am an artist and I use some power, OK?
Up until now, I have always charged my batteries with an AC 2/12/24 Amp
digital smart charger hooked up to my generator. My generator supplies
(2) AC 120V outlets with an average 10-13 Amps each. I have found this
setup to be pathetic in terms of performance, and am looking to set up a
more effecient system.
I will be adding solar panels soon also. But my main question is this:
Technically, all generators make DC power. They have an inverter built
in to convert to AC, since most everything uses AC. Then, my
smart-charger converts back to DC to charge the batteries. Isn't this
inefficient? Wouldn't I be better off with a DC powered smart-charger
that I could hook directly to my generators alternator, or to my 130A
truck alternator? But I need something smart, because I don't want to
ruin my batteries by overcharging.
Would the Solar charge controllers work for my application? I know that
are some DC smart chargers available for sailboats. Is that what I
should be looking for?

Let's see: "Solar Panel size 210 X 210 cm", "10.00 Volts at > 1000 ma"
Thus, size = ~ 83 inches x 83 inches; output = 10 Watts.
Seems a bit impractical for backpacking, or anything else.
Nice way to get a plug in, tho'<G.

I bet that's 210 mm. Or else that's a HUGE backpack.

And every thing else is giant size!
More likely 210 mm.
