Before our next trip to MX I'm thinking about one of the Engel portable fridges. Last time down we saw a few in service
and the owners raved about them. One guy had two, one used as a freezer
and one as a fridge.
According to the specs the power consumption
varies between 0.5 and 2.5 amps. I don't know why there is such a range. Here is a link to the one I'm interested in.Engel Australia - Portable Fridge-Freezers
system is this, one group24 starting and one group27 house.
Engel running 2amp 12 hours = 24 amp/hours (based on users statement of run times)
lights 2amp 4 hours = 8amp/hours
and CD a guess at 4 amp/hours
fans another guess at 6 amp/hours
various pumps 4 amp/hours
Total daily demand 42 amp/hours
Our boat is small, 27 feet, we have very few electrical
items, the fridge is a huge splurge for us.
105 amp/hours from the G27 house battery
So this puts me at about a 40% discharge rate, the current battery
is a new deep cycle.
We also have a Kyocera
panel, using these assumptions
5 amp/hours 8 hours of sun 40 amp minus a fudge factor of 25% equals 30 amp/hours.

Here is the question, is the one Group 27 big enough to run everything with the solar
and say 30 minutes of engine
run every morning?
Or should I get another battery in parralell for the house bank? I have the room to add one if I relocate the engine
battery, easily done.
