The results of the cool down test are chilling.
Cooling 2.5 gallons of water from 39 to 33 took 5 hours and used 4.75 amps or about .95 amps an hour. That is not linear by the hour. It varies. More in the beginning less at the end. But if you run this out for 24 hour you are going to need 25 amps. + what you use in the trailer – In my case 31 amps. BUT that is not the case since after the food reaches the desired temp the energy consumption drops to about a half amp. My two solar panels will have no problem with full sunshine and even clouds. BUT this is no substitute for real world testing. The 55 amp hour batty (25 useable amps) might work with the two solar panels I did would not feel comfortable with that setup. With 115 (50 useable amps) I would be using 31 amps and still have about 20 amps left with no charging. With the solar panels limping along at half capacity on a cloudy day I would be fine. Under trees on a really shadow less day I might need a third panel – time will tell. But I am confident I can do fine with 2 panels. Keep in mind this is the cool down mode. Maybe the first 12 hours after the food purchase. I use very thin solar panels and I could easily carry a third panel with my controller.
For the second test I want to verify the battery drain after the water was cooled to 33 degrees and find how much electric it takes to keep the food there overnight. I am trying to simulate after the restock food and is chilled to the right temp. I am thinking I can get by for several days with the food and want to know what is the drain over 24 hours. For this test I set the fridge temp to 33F I started with the battery freshly charged and ambient temp of 65F
Over 12 hours the fridge used ,47 amps an hour to keep th3 water at 33F. That is truly amazingly low energy consumption. 24 hour consumption would only be 11.28 amps (in my living room).
So under ideal stable lab conditions (I rounded up) at 12 hours of daytime @ one amp an hour - 12 amps consumed. At night 6 amps consumed @ ½ amp an hour. 18 amps is a good starting estimate (for me) until I can get outside in some hot weather.
I think I will be in good shape for fresh food this summer. Only question in my mind is several extremely cloudy days under shade trees. I will pick my campsite with that in mind.
For now, I will load the fridge 24 hours before I leave for a trip and have everything cooled down in advance . That works to my benefit by shortening the time it takes for me to leave. I can now take the trailer to work on Fridays and leave from there with the food keeping cool while I am working!
At this point I SHOULD be able to get about 3 days of fridge/freezer with no recharging. I am guestimating the fridge will average 18 amps a day or .75 (point 75) amps an hour average (more data is needed for different conditions). With this solar panel configuration - full sun or clouds - unlimited refrigeration. MAYBE unlimited refrigeration in shade with clouds.
There is still more meat on this bone.
First one died 4 hours after I received it. Replacement is working fine.
Runs on AC/DC. Good News I can connect to both AC and DC live power sources at the same time The Fridge will automatically switch to AC when it is available. No need for me to swap plugs when changing power sources. Very convenient.
Has a built in pull out basket for convenience. I suspect it helps air flow to. There is no fan on the inside to circulate air. Camco makes a fan for fridges that runs a month on 2 D cells which circulate air should I ordered one to see how much it helps.
There is an LED light inside that lights when the lid is opened and there is a digital display for setting and monitoring temp and features
Direction say to pre cool contents and fridge as you would with an ice chest – but I wanted to get an idea what happens when fridge and contents are not cold I filled some containers with 9 quarts of water – room temp and powered the fridge with a fully charged 35 amp hour AGM battery. Fridge was room temp too.
On DC the fridge draws 4 amps with the compressor running but it does not run long. On AC it only draws .44 amps with the compressor running. Out of an hour the compressor cycled on 3 times for 8 min for a total of 24 min an hour and was off the rest of the time. When it reached shut off temp it drew .06 amps almost nothing. The average draw was 2 amps an hour measured with a meter over 8 hours on the battery (keep in mind this is with room temp water in it – NOT PRE CHILLED). The 35 amp hour battery produced about 15 amps before reaching 11.4 volts which is about right. More testing is needed. The point is with my new battery is 115 amp deep cycle battery I hope to get about 60 amps out of it before reaching 11.4 volts. That would be a few days of cooling.
Today with the food cold and not opening the lid very much it only drew .65 amps an hour which is AMAZINGLY low power usage. If it draws .65 half the day and 2 the other half that’s a total of 31 amps a day. Might be no problem for my solar and 115 amp battery. Again time will tell. On all but the worst cloudy days I should be fine. Couds for a few days in a row might be a problem. I can’t wait to find out.
I noticed the fridge is cycling on less and staying off more now that the contents are cooler. This is not the kind of fridge I expect to throw warm drinks and have them quick cooled.
After 24 Hours. 9 Quarts of water with the fridge set at temp of 31
Top layer was temp of 38.
Middle layer was 35
Bottom was 32.5
Love the whole kit together! Highly recommend!!! I camp in my Tesla Model S and it works perfect for that too!
We decided to invest in the Dometic 95 instead of more panels and I am not disappointed. We have it split between a fridge and freezer and I really like how it uses one compressor to cool two different compartments controlled by two thermostats. It will switch the cooling between compartments.
When running the fridge takes about 65 watts, which is about the same amount of power as a laptop computer. For comparison our standard fridge took 125 or so watts while running. We have managed to make it through the night without losing power for the week or two that we have been using it (in winter in Maine). It seems to work by turning on fairly frequently and staying close to the set temperatures. It sounds a lot like a microwave oven when it runs.
The fridge is very well made, and I appreciate the details such as the interior lights (that turn on even when the fridge is not powered), and the latches. So far it is large enough to store enough food for two people for probably 4-5 days. I would definitely invest in the 95quart model if it is your only fridge.
My only complaint about the fridge is that I wish it was a bit more insulated. One night we shut off our inverter and the temperature did not hold well at all in the fridge. But I suppose I could also buy the insulated blanket that is available.
Update: We have now owned it for about 4 months and are still very happy. It keeps its temperature well and does a nice job with fussy produce. We have yet to lose power in the middle of the night with it running so this indicates that it's power draw is low.
