leaving the fridge on is NOT storage mode
there is no solar at night
in the 5 hrs of mid-day peak solar you have to replace every ampHr removed from the batteries during the 19hrs of low solar & no solar
also what happens if you have (2) cloudy or rainy days
your down 30ampHrs or more
how much overhead will you have to recharge the battery bank
i would prefer 200 watts of Solar
i assume the fridge has food in it
easy to have a $100 worth of spoiled stinky food in the fridge
when the batteries are dead
you've already experienced this once, don't go short on the solar
