R600 can be harder to service NA. A client bought a Korean brand (can't
remember which one) last year and it had a leak. There was not any service
for them in California and they gave him his money back.

actually Isobutane, and if anyone wants me to extol the virtues of these
refrigerants for use in North America, don't stop me from ranting. Europe
has been using these (R600-R601 and other blends) hydrocarbon based
refrigerants for well over twenty years now with good success. They are
more environmentally benign as well.

AC fridges using 1.2A for the smaller unit to 1.9A full size. Both have
freezers. LED interior lightning and use R600 which is alcohol. My clients
LOVE these units and my batteries based systems do too!

It's also worth
mentioning SunDanzer; they has upright AC & DC fridges, plus chest models.
David Bergeron is very responsive & helpful. While I agree w/ the advice
for most people to go conventional & AC, there is still a place for Sun
Frost-like products. My SF RF-12 is still running from 1984, & a SunDanzer
freezer for at least 10 years now. DC can still make sense in specific
applications, -) Ian

I know this isn't what Will is looking for, but just in case anyone
still needs a 12/24vdc model frig, I got an ARB 60 qt at the beginning of
the summer, and it's been a champ. Especially for mobile applications, it
doesn't need to be level.

Temp setable from zero up, I'm using it as a frig set at 33 degrees F. It's
been in a hot van running all summer, using about 100 to 150 watthrs per
day, less than rated, pulls about 3 amps at 12 volts. I tested out deep
freeze mode and it was closer to 400 wh/day, but starting with hot water
and freezing it solid. I really like the design of the ARB too. It's got
good dimensions for food and beverages. 90 beers! I've got a 24v
Novakool at home that's been running solid for about 15 years. But when it
putters off for good I'm replacing it with an ARB... Rebekah

Off-grid refrigerator
Almost 25 years ago, when we built our off grid
home, we looked at the limited options then available one of which was the
Sunfrost. After looking into things like relative efficiency, initial
purchase cost and system requirements, it became pretty obvious that the
Sunfrost was an overpriced option that had too many problems. For half the
cost we bought a Vestfrost and then simply added a bit more generating
capacity to our array at far less than the difference in cost between the
Vestfrost and the Sunfrost. It was the best decision on appliances we ever
made. The 120 vac Vestfrost was a bit less efficient but since we were
generating our own power that difference was irrelevant as the cost to
provide the necessary capacity to handle the efficiency difference actually
resulted in us saving money and also gaining a very reliable appliance.
That was then and the Vestfrost was massively more efficient than the
standard refrigerators then available. Now, that model of Vestfrost is
nowhere near as efficient as the newest Energy Star compliant refrigerators
available at most appliance stores. Don't waste time or money searching for
another DC refrigerator, there simply isn't any benefit. It will be cheaper
to buy off the shelf and if you have to add a bit of generating capacity
getting another panel on your system will be way cheaper than than it was
for us back in the day...and back then it was still the better option.

Hello Off-grid Wrenches,
After 10+ years my Wife is finally sick of
our Sunfrost RF-12. We'd like to upgrade to something a little more modern
that doesn't leak water all over the floor when it's humid
For you
off-grid installers what's your go to refrigerator recommendation? I'm
going to go through the energy star website but I thought I'd consult with
the experts too. I'd like to find something that has a form factor similar
to the Sunfrost although I know that's going to be hard to find.
Thanks,
Will White
