I purchased this T50 unit for a van conversion I will be doing and the cost for this brands dual zone is significantly less then a Dometic CFX along with it was the only one I could find with dual zone in a 50 quart size I thought I would take the chance. My two concerns were quality and efficient to run off of solar power. When I first started the unit it ran for about a minute then faulted. I reset the fault and let it sit for a while thinking it may have been placed on its side during shipping. I have not had a fault issue since. I have had this unit for just under 2 weeks and have done many tests that follow. On each of these tests I opened the cooler door three times each day for abut 20 seconds each. I ran the cooler in single zone mode from room temp to a set point of 33 degrees F and let it run for a day then shut it down for a day to let the cooler warm back up to room temp then repeated this process 3 times. It ran great and with a set point of 33F the coolers actual inside temp was 36F. It took the cooler about 2 hours to reach temp and it draws about 11 watts every hour, keep in mind that this wattage average was over a 24 hour period and you had the initial pump run (60 watts) for its initial cool down. I then ran the cooler in dual zone mode from room temp to a set point of 40/10F (if using the dual zone mode as a cooler/freezer make sure the L shaped zone is the colder zone) and let it run for a day then shut it down for a day to let the cooler warm back up to room temp then repeated this process 3 times. It ran great again and with a set point of 40F the cooler zones actual inside temp was 36F and with a set point of 10F the freezer zones actual inside temp was 8F and it did freeze a glass of water. It took the cooler zone about 2 hours to reach temp and the freezer zone about 3 hours to reach temp. The cooler draws about 20 watts every hour in dual zone as a cooler/freezer setup, keep in mind that this wattage average was over a 24 hour period and you had the initial pump run (60 watts) for its initial cool down. I wanted to see how long this unit would run on my Yeti Goal Zero 1400 and by math (1400Wh/8W/1h) should be about 175 hours or 7 days. As a note in order to use any of these compressor type coolers that have a low voltage shutoff feature on a 12VDC lithium type battery you need to have a regulator or your cooler will shut off when your lithium battery reaches about 50% capacity. Yet sells a regulator just for this reason. My yeti was at 99% when I started and as of now it is at 40% and has been running the cooler for 89 hours (3.7 days) with 40% more battery to go.
