Too many choices.
Steve:There are almost too many choices in the refrig. market (Adler/Barour, Grunert, Norcold, Frigoboat, Isotherm, Kenyon . The most popular is probably A/B. My choice is Technautics Marine. High quality with less power consumption (at a premium in cost). There new unit Cool Blue is suppose to be about 50% of the consumption of the more popular units. They do custom cold plates if required too. You really need to research this issue.Some of the unit have AC and DC options. I do not see the purpose of an AC option. If you have shore power and a battery charger you might as well be on AC power only. You will need at least one battery just for the unit but two (200 amp) is probably more in line. If you do not have an inboard engine you need to figure out how you are going to charge the batteries when away fromt he dock. Then which ever unit you purchase you need to figure out if you add insulation to your ice box and where are you going to add the additional batteries and charging options. Figure that this is going to cost from $1000 - $2500.I got to tell you that it sure is nice to have a cold brew awaiting your arrival to the weekend condo.
