I'm trying to learn about inverters, and how to put a
system together. I want to use it pretty much just
for my refrigerator (about 800W), and my TV/VCR
etc. It seems like it would be cheaper to get two
less powerful inverters, than one powerful one.
So far getting two of the 1200W for $120 each at:

seems like the best deal for me. That would leave
me plenty of head room--especially on the TV
circuit--for including other things. Does anyone
know of a better deal?

How do I figure what size batteries to use? Should
I keep the batteries separate for each inverter, or
is it better to connect two or more batteries and go
from there? If so, how to connect the batteries
together, and then how to go from there to the
inverters?

I'm lead to believe that any inverters I can afford
would produce a square wave instead of a sine
wave. How to know what influence that would
have on my TV's performance? The TV works
great using the Generac 4000W generator I'm
using now. Can I expect it to be different using
the inverter?

Thanks for any help!
