Generally, you need one solar watt per battery amp hour but living in Washington you may need 1.5 or 1.75 watts per amp hour. Have you consulted a solar wiring chart to determine proper wiring?

The controller you buy needs to specifically say it works with lithium batteries. You'll love not needing a generator! Seems your current fridge is a power hog.
