I'm considering an EdgeStar. Found a 63 qt for $419, free shipping.
To run the fridge I have a goalzero 350 charger with 30 watt panel. Will that be sufficient or should I get another panel to be safe?
Good deal? Enough power to run it?
I Welcome your feedback!
inadequate especially if you get any cloudy days. I have the 43 quart edgestar. I have been running it nonstop 24/7 off of solar power since I got it about a month ago. It's hooked up to a 75 amp hour 12 volt agm battery, that is connected to a 120 watt kycora solar panel (rated 7.45 amp) on the roof of my RV.
My edgestar set at 39 degrees consumes 23 amps of electricity during 24 hours of use. If I set it at 37 degrees it consumes 27 amps of electricity during 24 hours. This I measure with an inline dc wattmeter which is fairly accurate. inside temperature in RV was between 45 and 90 f throughout the day.
The most amp charging I get from the solar panel varies between 3 to 6.5 amps/hour during sunlight hours, this is with an mppt charge controller. About 30/35 amp hours a day total on a good sunny day. Subtract the 23 amp hours and it doesnt leave much to run other things.
I was originally hoping to use the fridge as a freezer and I attempted it but even when I set it to 20 degrees it drain my battery to 11.5 volts after 2 days with the solar panel unable to keep up with it. At 11.5 the yellow light on fridge starts blinking and the fridge will reset to 40 degrees. It took a week to recharge battery back up to 12.5 volts but fridge ran fine set at 39 degrees and keeps my gallon of milk fresh at that temperature.
I already got a larger 240 watt solar panel I just need to install it. I prefer to run the fridge and also power my 17 inch laptop at the same time. The 120 watt solar panel just barely does the job. For me its all off-grid, no gas generators or plugging into wall.
I wouldnt even attempt doing it on a 30 watt panel (rated about 1.75 amp) which might max out at 1.3 amps in full sunlight. Which might get you 11 amps total in a day. 2 X 30 watt panels might get you 22 amps in a day. If the solar panels will just be auxillary charging it might work as long as you have some other source to charge the battery.
The 350 charger might have a 35 amp hour battery (from the weight of the unit) that can at most power the fridge for 24 hours before recharging.
That is from my own use, others may have different results using different size solar panels and batteries.
