You might be able to even get your existing refrigerator converted to use DC electricity if there are no sophisticated electronics.
This opens a new avenue for an innovative investor / businessman.
Many years ago I assembled a miniature A/C / Fridge like gadget with the help of refrigerator guy to use in a orchid growing chamber where you need low temperature.
[When you propagate orchids by seeds or mericloning you have to keep them below 25C for many weeks/months continuously. Running an A/C from start to end of this period makes the cost of plants very high.
Hence we tried to give a Solar power solution .]
We used car A/C compressor run by 12 V motor pulley.
Due to high cost of Solar panels we could not make it that good and viable.
I think 40-60W panel was over 60,000/- those days.
Thank you Lokka1 for reminding this again !
12 - 24 V mini refrigerators could become a popular household item in future . 40W = 7,000 is very interesting.
