House/solar battery opinions
My current battery space is 20"L x 14"w x 10"H Going solar, and want to packs as much AH in there as I can (reasonably). Currently looking at 250 - 300. Price is not THE deciding factor, unless ...

I'm confused here. How'd you jump from amps (480) to watts? Is .06 a magic number of which I don't know the significance lol? Plus, in the Midwest, the charts only show about 3 hours of usable sunlight a day rather than 5.
We're back to the question I posed Almot - which is more important; the wattage of a panel irregardless it's voltage, or the number of amps being put into a battery at its charging voltage?
I'm curious about both of your answers...

Hi seraphim,
I prefer to calculate *grin*
480 x 0.6 = 288 watts minimum.
288 x 5 hours = 1440 watt hours
1440 watt hours /12.8 volts = 112.5 amp hours
parasitic loads are typically 36 amp-hours per day

It seems that 480ah is the most I can squeeze into the available space.
And if I use 100ah a day, then I only have two days of battery power to use, unless I can recharge that amount on a daily basis - which I doubt lol.
