I forgot to mention that one reason to consider a shorepower based charger is to make sure the beer is always cold. There will be times when your solar can't keep up due to shade, clouds, or batteries discharged overnight with sub optimal solar availability in the morning. I like to plug in the night prior to a trip to pre-cool the refer, and reducing the number of cycles on the batteries will extend their life too. In addition, some charging relays / battery combiners won't close if batttery voltage gets too low, so the only way to recharge is to plug in.
