Certainly that is possible, I have a very basic system at home in the
south of England consisting of a 40w solar panel, charge controller,
two 110 amp leisure batteries and two inverters. One inverter is a
pure sine wave (600w) and the other is a modified sine wave (1200w)
they are basically for emergency power in case of a power failure, but
I do have some 12v lights run into the house and garage which are in
general use. The pure sine wave inverter would run the TV and
computers if necessary. This system copes well over two to three days
as long as the inverters aren't used constantly and sparingly. I do
intend on adding another solar panel a little later for the darkest
and shortest days. Going back to your set up I would be very
interested in hearing how you get on. Good luck for now.
