In anticipation of a 74l fridge that I am planning on buying, I need to think about powering it. I have a short wheel base 90, with a roof tent. The fridge draws max 5A, so I am trying to work out what I need to power it. I'm thinking that a 100Ah battery with 100w solar panel should be enough. I think I would prefer it to be a stand alone setup. Are there any guidelines to ensure that my beer never becomes warm?
