[Travelling Three]

We have a 2017 Montana 3661RL, 40', 5 slide outs with a large 2 french door-1 freezer door Samsung refrigerator. How many solar panels would I need to keep the battery charger charging and providing enough power to the AC inverter thereby keeping the batteries charged and the fridge working when I lose power? How much power does each solar panel provide and how physically large are they? Thanks!!
