Though I don't have any plans on running a fridge off any invertor, one of my projects planned for January is this home built 12 volt setup. .

This along with a 3-4 golf cart batteries will allow the use of a few 12V LED lights, laptop etc in the house.

This setup along with solar is sufficient for basic needs and precludes running a big generator all the time. The fridge and freezer depending on the ambient temps only require periodic runs to keep cold.
