Off-Grid Solar Powered Refrigerator
To do their job, fridges and freezers need to be powered on constantly. If you have an unreliable power source, or you’re in a remote location, you’re going to have issues if you have food that need to be kept cool. Industrial Insulation Systems has a solution, which is basically a solar-powered refrigerator kit.
Using the sun’s energy, the solar panel charges an internal battery. Additionally, due to the size of the solar panel, it also provides some shade for the refrigerator. The refrigerator/freezer is able to maintain temperatures down to minus 20 degrees Celsius, which is what’s needed for 99.9% of food typically stored in a fridge or freezer.
A full charge of the batteries gives 24 hours continual chilling time, thanks to a bank of four 12V 100Ah batteries. The batteries are mounted out of the way at the base of the fridge. The solar panel itself is mounted on the frame of the refrigerator, keeping the unit compact and easy to move.
Unfortunately no pricing information is available on the website. A great idea though, and very suitable for remote locations, disaster relief, boats, humanitarian aid and domestic home use.

“A full charge of the batteries gives 24 hours continual chilling time”
I wonder how long it actually takes to charge the batteries. I’m doubting that you can use this thing continually… a full charge will last for 24 hours but after that it probably can’t keep up.
Hi Kevin
My guess is that it’d take 20 to 40 hours for a full charge. Solar charges do tend to take a while to charge up batteries. If the solar panel is used in addition to a standard electricity supply, 24 hours would be enough.
