I am set up with 2 6v batteries and 300 watts of solar. Gets us a week pretty easily. And that's been in the winter using the heater. However, we use zero 110v appliances. Not even a microwave. No inverter. Some day I will do some leg work to get four 6v batteries. We either cook outside on the BBQ or inside with the stove and oven. I am also in the group that discourages running generators. I will eventually have one, but it will only be used in emergencies. And in our trailer an emergency isn't "needing to use a hair drier"!
