Report Refrigeration in Tech Talk Posted December 10, 2019 +1 on the CFX-40 Did 2 weeks last summer with one of these on the 930, with 170 watts of available solar and 196 amps of deep cycle batteries. Started with all the meat packed in and frozen while on 240v at home, drove to BOI with it running on 12v in the ute, chucked it in the boat and buggered off. Ran it on -18deg C during the day and switched it off at night. came home with still frozen meat. And during the day, as the food ran down I replaced the gaps with water bottles and beers. They went from bilge temp to frosty in an hour... One day I'll have a grown ups boat with charging systems and inoard/icebox and I reckon I'll still rock the Waeco!
