FRIDGE
SELECTION FOR MOBILE HOMES
For mobile
homes and off road vehicles, there are several
options to meet your refrigeration needs.
1) A Standard
240V fridge: In our opinion, this is the worst
option if you wish to run the fridge from your
battery. After allowing for inverter inefficiency,
we generally have found that a 240V fridge will
use about double the power of a 12 - 24 Volt compression
driven fridge. This means more batteries and more
solar panels. For a more detailed discussion of
this point, see the Fridges section in our FAQ
Articles.
2) Esky
with Ice: This works pretty effectively for the
occasional camping trip but buying ice all year
round is going to be rather costly.
3) LP
Gas Fridge: These generally work pretty good, however,
you are not allowed to run them while the vehicle
is moving. Some models can struggle to keep cold
in tropical weather.
4) LP
Gas with 12 Volt and/or 240V Options: You can run
this fridge on gas or on 240 Volts (if available)
while you are stationary. When the vehicle is moving,
you can run it from your battery. However, do not
expect to run this type of fridge on solar power
as they use too much power.
5) A 12/24
Volt DC Compressor driven fridge: This is the most
efficient type of fridge to run from an auxiliary
battery. If you drive the vehicle for at least
a few hours every day or two, you should be able
to keep it charged from your vehicle. However,
if you wish to camp for more than a couple of days
without power, you will need to use solar panels
(or some sort of generator) to keep your batteries
charged. In general terms, select a fridge with
a Danfoss compressor. A chest or smaller fridge
will use less power than a front opening and/or
a larger fridge. Contact an experienced solar shop
to work out your solar panel and battery requirements.
6) A 12/24
Volt Eutectic fridge: This type of fridge has eutectic
fluid (rather than conventional insulation). Once
run for 4-6 hours, it will then hold its temperature
for some 2 days. Using our 73 Litre Eutectic Chest
Fridge in conjunction with a good deep cycle battery
could allow you to maintain your fridge for 4-6
days without solar or other power input.
In conclusion,
we would advise that selecting a fridge for your
mobile home is perhaps the most important decision
you make. We suggest you seek good advice to help
you make this decision.
