Re: [Electric Boats] Re: 12V DC -> 120V AC vs. 48V DC -> 120V AC

 

I am pretty sure RV fridges are not designed to work at an angle that sailboats operate at. The up and down motion in waves may also be a problem.

RV's have fridges with 120AC, 12V DC, and propane.
Any reason why not to use one of these, and skip the propane connection?

Hi Bob 
I am new here but I have a little
experience with this kind of issue. 
I was a regional technical advisor
for West Marine for many years and a yacht broker among
other things.
I think
your 100% right that a 48 volt inverter will be more
efficient. 
A few
years ago a 48 volt inverter might have been dramatically
more expensive but I have seen that gap narrow
significantly. 
For
example  AIMS Power inverters have 48 volt units for just
$50 more then a 12 volt model with the same capacity and
also can recharge your batteries with a powerful
charger. 
You can
also use smaller lighter wire to connect it then you would
need with a 12 volt set up so the compete 48 volt system
might actually be cheaper!
Check out www.aimscorp.net
(I am not affiliated with them in
anyway)
On the other
hand if you really want to keep it simple and save some
money you could just get a high quality cooler like a Yeti
and some dry ice and you will be able to keep block ice or
food cold or even frozen for a week or more.
Have fun and enjoy your cold
beer!Ken
Here is a unit I would recommend for
you.
