IF I am reading correctly almost your entire solar output on a sunny summer day is going to the fridge . I am trying to determine the full cost of a compressor fridge . The extra solar plus extra battery . On the other side there is no cost for propane . To be honest I have had better life span out of my RV gas fridges than I have from the ones in my home . One I replaced last year that was 40 years old , and the other is still going at 48 years old . To be fair they have not been running every day for all those years . Still in the learning process .
No, I said the fridge consumes about 800 watt-hr per day max and on a sunny day we get 900 watts PER HOUR at high sun. So the juice to the fridge for an entire 24 hour period is replenished in under an hour. In reality because of limitations on absorption charging of batteries it might take longer than an hour to replace the charge.
