Ok, the payback time is probably two or three centuries, but
I'd like to at leat think about this.
Situation: I've got an apartment whose main power use is
a manual defrost freezer, pulling about 90 watts when in
use and running about 1/3 of the time. In other words, the
total monthly kw-hr usage is something like 25 kw-hr when I'm
not around (and more, of course, when there).
I can put about 30 square feet of solar cells outside
the window, which would get me something or another...
So what I'd like to do is get some sort of "a/b switch"
which will feed the freezer from the battery bank when
it's charged up, or from the utility line at other times.
Should be a simple concept. Solar cells, battery,
power switcher/controller.
Obviously such stuff is out there, but I'm blanking on
the search term for this controller.
Thanks muchly.
(Oh, and all suggestions appreciated. Even the "you're
a moron, this will never make sense" type).
