Solar is great in theory, but 2 problems 1) I'm driving during the day and stopping after dark and 2) counting on solar in November in this part of the country seems like a bad idea.Solar panels on the roof charge all the time. Can't help you with November.
..a 300w inverter for a couple hours in the evening plus run the furnace all night, I can't imagine I'll get more than 1 day of that with a battery setup up, will I? 300 watts for 2 hours would be about 60 amp hours, wouldn't it? Can I get significantly more than that with a 2 12v parallel or 2 6v series setup?A 300w inverter doesn't mean it always draws 300w. It draws what you ask of it, plus a little bit for itself. If you actually did draw 300w, it's more like 50ah. That's about 1/4 the capacity of 2 6v in series.
