RE: 12v Fridge's and batteries
I just returned from a full seven days camped in the Central Cascades in
Washington State,  and annual astronomy event I go to every year.  I'm
running a Norcold (installed before the Vitrofrigios was 'discovered').
Temps in the 70's to high 80's most days, no lower than 50 at night.  Like
in the past, my aux battery (100 AH AGM) would drop to about 12.2 V
overnight but two 50 watt solar panels pulled it back up during the day (and
that with one panel going bad the second day there, output on that panel
dropped to about 9v the second day instead of the 19+ V I was seeing from
the other panel.  I've gone up to three to four days on the 100 AH battery
then I'm down to about 11 V, that's w/o the solar panels hooked up.  I'd
expect about the same from the Vitrofrigio, the power consumption specs are
about the same.  There was some interesting info from Vitrofrigio posted a
couple of weeks ago about tweaking the thermostat so that the 'fridge
doesn't cycle on with small drop in internal temps.
BTW, I was trying to keep the 'fridge temp at about 40-42 F but it kept
wanting to pull itself down to about 38 F, kept turning it down.
