A little clarification
Some members are not specifiying 'watt hours'
A fridge drawling 800ma aka approx 10watts, will use 240 watt hours of power in 24 hours
Your furnace using 8 amps for the blower will use 100w while running if total run time is 4 hours out of 12hrs, 30% duty cycle for the night
It will use 400 watt hours aka 0.4kwHr
A 100watt solar panel might produce 400 watt hours per day
It varies with each person's install and camping location etc
My 600+Watts of solar never produced more that 2200 watt hours in one day
So that is less that 400 watt hours total per 100 Watts of solar
Usually much less
100w is good for extending the week end into a three day affair
I don't think it's enough for a family of five for five days
I think you will be operating at deficit, use more each day than the 100 watt solar creates
I think 200 Watts and the second battery would be a better choice
This is not really an either/or situation, it is a use both for the desired results situation
